SECTION A - READING

Read the following passage and answer the questions that follow: 12

Servants of People

1. The Father of the Nation wanted ministers and bureaucrats of the new independent India

not to live as „Sahibs‟

2. This is evidence from Gandhiji‟s allusion to the ministers of Bengal when they came to

pay their respects to him on August 15, 1947.

3. He said, „Today you have worn on your head a crown of thorns. The seat of power is a

nasty thing. You have to remain ever wakeful on that seat. You have to be more non-

violent, more humble and more for bearing. You had been put to test during the British

regime. But in a way it was no test at all. But now there will be no end to your being

tested. Do not fall a prey to lure of wealth. May God help you. You are there to serve the

villages and the poor.‟

4. The emphasis on serving the people had always been the cornerstone of Gandhiji's

utterances on the role of public men. These days when the word „public servant‟ is used

so freely, it may be apt to recall Gandhiji‟s concept of the term. In fact, he said in clear

terms in The Harijan of January 12, 1942, „Legislators are not the masters, but the

servants of their electors- the nation‟.

5. Such a public servant or public worker, according to Gandhiji, should place the country

above him and should reduce himself to a „cypher‟. He can have no pride, no power, no

prestige except such as his service gives him.

6. As for their private lives, they should be so simple as to inspire respect or reverence

rather than provide material for tabloids; „An Indian minister or Governor should use as

far as possible only Indian-made goods- bungalows and motor cars should be ruled out.

Of course, if he has to go far on an urgent business, he should certainly use a car, but its

use should be definitely very limited- he should give one hour to productive physical

labour….Members of his family, including children should do all household work

themselves. Servants should be used as sparingly as possible.‟ says Gandhiji.

7. Today, there is a growing demand for greater transparency in spending of money by

political parties and auditing of party accounts, as also the incessant demand for

disclosure of all assets of all candidates standing for elections.

8. It is ironical that such demands be made in the country of Mahatma Gandhi. Gandhiji was

meticulous in keeping accounts and in making these accounts public. Public money

belongs to the poor public of India- there is none poorer on earth. Carefully kept accounts

are in sine qua non for any organization. If we do not account for every single paisa we

receive and do not make a judicious account of the funds, we shall deserve to be blotted

out of public life.

9. Writing in Young India on August 20, 1928, he said, „The safety of the public fund lies

more even in an intelligent vigilance of the public than in the strict integrity of those who

are in charge of funds. Absolute honesty of the trustees is a necessity, but public inertia is

a crime.‟

10. With regard to spending of public money, Gandhiji always exhorted his workers to be as

miserly as he himself was and not become lax or extravagant simply because the money

was not their own! Also he said, „We must learn to make our expenditure commensurate

with our national resources, not with what generous donors may give us.‟

11. Wasteful extravagant expenditure, such as reception committees often indulge in,

amounted to „criminal misappropriation‟ of funds and he laid down a certain conduct and

code: recruit a few volunteers, minimize motor hire for local purpose, maintain separate

account for those who bear their own expenses and collect the same from them, reduce

printing costs, „purse‟ money not be spent on decoration and no addresses be presented

out of „purse‟.

12. He asked the organizers of his tours in provinces to be simple and economical in catering

for the party. He admitted, „I know that of my party I am the costliest member to feed but

let my hosts not ponder on my weakness, by importing, tempting superfluities.‟ Public

men were only trustees of the public and they should not abuse the trust reposed in them

by using the money for personal use.

13. Gandhiji was perhaps the only political leader who owned no property or had no bank

account of his own. Asked how he bore his expenses, he had said, „I draw nothing from

the AICC or Gujarat Committee. Friends fund my travelling expenses including food and

clothing. My hosts cover me with kind attention. People present me with much more

khaddar than I need. The balance goes to clothe those who need it or is put in the general

khaddar stock in Khadi Bhandars.‟

2.1 Read the passage given below: 8

The word „depressed‟ in common usage means sad, frustrated, fed up, bored up and

pessimistic. The mood of a depressed person is much lower at his or her best moments than

the mood of the normal person at his or her worst. Depression is a state of mind. It is

specifically a mental disorder characterized by a lowering of the individual‟s vitality, his

mood, desires, hopes, aspirations and of his self-esteem.

Depression arising out of environmental factors is called reactive depression whereas

depression arising out of some biochemical changes in the brain is called endogenous

depression. If depression is mild or moderate and if the individual is in touch with his

surroundings, it is known as neurotic depression. If the individual is severely disturbed and is

not able to comprehend what is happening around, such a state is called psychotic depression.

At present, social structures and values are undergoing transformation from traditional to

modern. There is a rapid stride in urbanization and industrialization leading to the breaking

up of joint families and property. This has ultimately weakened the traditional families, social

position and status of the aged in the family. From time to time changes in the institutions of

marriage and family have diminished the control of parents over their children. It has

increased the freedom of children and they view the aged as a useless and non-productive

entity. Modernization has eventually led to the degradation of their status and authority.

Consequently the integrity of the family and the existence of the elderly as an integral part of

the family are being uprooted. The importance of their functional positions thus declines and

consequently their authority and much of the respect and prestige that they enjoyed earlier get

faded. These changes generally bring about depression in older people.

As old age advances events at home may also contribute more to their problems. The„empty

nest‟ feeling arising as a result of the grown up children leaving the home, daughters

departing as a result of wedlock and sons leaving station in pursuit of higher education or

jobs may make the aged more lonely. The loneliness also arises because of premature loss of

spouse. This would deprive the person of a long standing emotional bond that had provided

plenty of emotional succour and security. The loss wherever it might occur in the later years

leaves the individual terribly lonely and at the mercy of the sons and daughters-in-law. Added

to these the increasing gap and interactional stress and strain in the family may leave the

elderly without peace of mind. The elderly as a result of these developments feel

marginalised, alienated and left out of the main stream. The foregoing are the common

problems faced by most of the elderly. These either directly or indirectly lead to a state of

depression and make ageing for many an unwanted and unpleasant event to be abhorred.

Usually, the mild depression which is caused due to environmental factors is temporary. The

person reconciles within a short time and tries to forget the loss. Kind words, and timely

support of friends, relatives and family members help one recover from depression.

3. a) What is a tuple? How is a tuple different from a list? (3)

A tuple is an immutable sequence. It is represented by () Where as a list is mutable. It is written in [] (1) A tuple is used when there is no chance of changing the data. T=(1,2,3) l=[5,6,7] T[0]=4 l[0]=0 is valid (1) T=T+(4,) will create a new object of T, old T is inaccesible now. In a list, such an operation will not create a new list object. (1) b) Write a program that will take a list . Create another list by applying the following rules on the first list. (3)

i) If the element is a number and divisible by 3, change it to 1 ii) If the element is a number and divisble by 5, add 10 to it iii) Any other case, add the element as it is

Print the new list. n=int(input(“Limit”)) l=[] nl=[] for i in range(n): num=input(“Number”) l.append(num) for i in range(n): if l[i].isdigit(): (1/2) if int(l[i])%3==0: (1/2) nl.append(1) (1/2) elif int(l[i])%5==0: (1/2) nl.append(int(l[i])+10) (1/2) else: nl[i].append(l[i]) (1/2) print(nl) (1/2) c) Name the function/method required required for (1)

i) Finding the ascii code of a character. - ord() (1/2) ii) To make the first letter capitalized. <string>/capitalize() (1/2)

d) Explain the role of linker and loader in compilation of a program. (2)

Linker – Object code of the program that reaches the linker is a bianry. Still the system cannot execute it because some important libraries needs to be linked to run the program successfully.Linker links the libraries to the object code with the help of OS. (1) Loader is part of the compiler that loads the entire program(source code+libraries) into the memory for execution. (1)

4. a) What is the difference between del and pop()? Give an example of each. (2) - Both statement can be used with lists, dictionaries (1/2) - del will not return the value, where as pop will return the value that is deleted (1/2) - del can delete whole object where as pop() deletes an element (1/2)

4

l=[3,4,5,6] l.pop() - returns 6 and deletes 6 from the list (1/2) del l – deletes the whole list, del l[2] will delete 5, without returning.

b) Write a program to find the sum of the following geometric series for n terms: s= a + ar + ar^2 + ar^3 + ......+ar^n (3) import math a=float(input(“Enter the value”)) n=int(input(“No: of terms:”)) r=float(input(“Enter the value”)) sum=0 (1/2) for i in range(n+1): (1/2) term=a*math.pow(r,i) (1/2) sum+=term (1/2) print(“Sum of the given series is “, sum) (1)

c) Write a program that reads a string and counts the special characters in it. s=input(“The string”) (2) count=0 (1/20 for i in s: if not i.isalnum(): count+=1 print(“Special character”,count) d) Write a program in python to find the sum of first N fibonacci numbers. Input the value of N. (2) n=int(input(“enter the value”)) sum=0 a=1 b=1 sum=a+b for i in range(3,n+1): fib=a+b a,b=b,fib sum+=fib print(“Sum is”,sum)

5. a) What is a state-transition diagram. (2) A state transition diagram describes all the states that a system goes throughalong with the events(triggers) which initates the process at each state and changes the state.

When vehicles go through turnings, they travel along a nearly circular arc. There

must be some force which will produce the required acceleration. If the vehicles

go in a horizontal circular path, this resultant force is also horizontal. Consider

the situation in which a car of weight mg is moving on a horizontal circular road

of radius r with a constant velocity v.

The external forces acting on the car are

weight mg

normal contact force R

friction Fs

The tires have a tendency to slip outwards. Hence, the frictional forces act

towards the center. Thus, for a safe turn we must have

However, there is a limit to the magnitude of the frictional force. If µ S is the

coefficient of friction between the tires and the road, the magnitude of friction

cannot exceed µ S R. We know that

23. Conservative Force: A force is said to be conservative if the work done by the

force (or against the force) in moving a body depends only upon the initial and

final positions of the body and is independent of the path followed between the

initial and final positions.

The gravitational force is a conservative force.

Non conservative Forces: A force is said to be non-conservative, if the work

done by the force, or against the force, in moving a body from one position to

another, depends upon the path followed between the two positions.

The best example for the non-conservative force is friction.

24. Law of conservation of energy states that the energy can neither be created nor

destroyed but can be transformed from one form to another.

Let us now prove that the above law holds good in the case of a freely falling

body.

Let a body of mass 'm' placed at a height 'h' above the ground, start falling down

from rest.

In this case we have to show that the total energy (potential energy + kinetic

energy) of the body A, B and C remains constant i.e, potential energy is

completely transformed into kinetic energy.

Kinetic energy = 0 [the velocity is zero as the object is initially at rest]

Total energy at A = Potential energy + Kinetic energy.

Total energy at A = mgh …1

At B,

Potential energy = mgh

= mg(h - x) [Height from the ground is (h-x)]

Potential energy = mgh - mgx

Kinetic energy = ½ mv2

The body covers the distance x with a velocity v. We make use of the third

equation of motion to obtain velocity of the body.

Here, u=0, a=g and s=x

1 ½ ½

Kinetic energy = mgx

Total energy at B = Potential energy + Kinetic energy

Total energy at B = mgh …2

At C,

Potential energy = m x g x 0

Potential energy = 0

Kinetic energy = ½ mv2

The freely falling body has covered the distance h.

Here, u=0, a=g and s=h

Kinetic energy = ½ mv2

Kinetic energy = mgh

Total energy at C = Potential energy + Kinetic energy

½ ½

Total energy at C = mgh …3

It is clear from equations 1, 2 and 3 that the total energy of the body remains

constant at every point. Thus, we conclude that law of conservation of energy

holds good in the case of a freely falling body.

25. Elastic and Inelastic Collisions. A perfectly elastic collision is defined as one in which there is no loss of kinetic energy in the collision. ... Momentum is conserved in inelastic collisions, but one cannot track the kinetic energy through the collision since some of it is converted to other forms of energy.

27. All gases are made up of molecules which are constantly and persistently

moving in random directions.

The separation between the molecules is much greater than the size of

molecules.

When a gas sample is kept in a container, the molecules of the sample do

not exert any force on the walls of the container during the collision.

The time interval of collision between two molecules, and between a

molecule and the wall is considered to be very small.

All the collisions between molecules and even between molecules and

wall are considered to be elastic.

½ ½ ½ ½ ½ ½

All the molecules in a certain gas sample obey Newton’s laws of motion.

If a gas sample is left for a sufficient time, it eventually comes to a steady

state. The density of molecules and the distribution of molecules are

independent of position, distance and time.

Cost concept: The cost concept requires all assets are recorded in the book of accounts at their price, which includes cost of acquisition, transportation, installation and making the asset ready for the use. Dual aspect : This concept states that every transaction has a dual or two fold effect on various accounts and therefore should be recorded at two places. The duality principle is commonly expressed in terms of fundamental accounting equation is ASSET = LIABILITIES +CAPITAL

a) Viruses are computer programs developed to copy themselves and

infect other files stored on the computer. These are malicious

programs that move from computer to computer by attaching

themselves to files or boot records of disks and diskettes

Worm is a program made to replicate automatically. A worm

replicates continuously until the entire hard disk space and memory

are eaten up and it may do so without any user intervention.

Or

.Unlike a virus, a worm does not need to attach itself to an existing

executable program or code. Worms harm to a computer or a

computer network by consuming bandwidth and slow down the

network speed whereas viruses almost always corrupt or modify

files on a targeted computer.

Interpreter - This language processor converts a high level language

program into machine language line by line as well as executes it. If

there is any error in the program, translation and execution stops and

the error is reported for debugging

Review Paper Answer Key 2018-19

PAINTING

1. The Konark temple was built in the form of a huge and colossal chariot drawn by a team of

seven horses depicted in the galloping mode. The entire temple was fitted with twelve pairs

of exquisitely decorated stone wheels. The horses were conceived in such a way that the Sun

God (Surya) himself drives this chariot, his place being inside the garbhagriha. The Konark

temple also marks the culmination of the temple building architecture in Orissa. Dedicated

to Sun God (Surya) 24 Chakras are seen around the entire structure which denotes the 24

hours of the day (time) and eight spokes within denote the eight fold path or the teachings

of Buddha. It got the name Black Pagoda by the Britishers due to its color and the view one

gets from the sea.

The humble beginning made in temple building activities in the 7th century A.D. The temple

consists of a deul (sanctum sanctorum or the sanctuary), antarala jagmohana (porch or the

mahamandapa) and a bhoga-mandapa, the latter being detached from the main temple

complex as a separate unit, but along the same alignment with the main temple. it stands on

a huge platform, the sidewalls of the platform utilised for the depiction of the richly

embellished stone chariots. The deul is a typical rekhadeula of the Orissan order marked by

the curvilinear sikhara, which could have originally marked with the typical karma-amalakas.

The jagmohana (frontal porch, mahamandapa) is the typical pidhadeul with receding pidhas

resembling a pyramidal roof. Both the rekha and pidhadeuls were crowned by amalaka and

a stupi. The rekha and pidhadeuls are square on plan inside, while the outside is a typical

example of a pancha-ratha structure known as rathas or pagas in Orissan architecture. Main

Extra information - (Temple Complex The temple complex consists of the Temple 1 (main

temple complex), Temple 2 (Mayadevi Temple), Temple 3 (Vaishnava Temple) and many

other subsidiary structures like the gateway, well, kitchen, enclosure wall, etc. the entire

temple was conceived as a huge and colossal chariot drawn by seven horses (three on the

northern side and four on the southern side) over twelve pairs of stone wheels. The twelve

wheels may symbolise the twelve months of the year. The grihas which are depicted include

that of Surya (Sun), Chandra (Moon), Mangala (Mars), Budha (Mercury), Brihaspati (Jupiter),

Sukra (Venus) and Sani (Saturn). The Rahu and Ketu are also depicted nearby.)

2. Indo Islamic architecture and its influence - the introduction of arches and beams, the

arcuate style of construction while the traditional Indian building style is trabeate, using

pillars and beams and lintels. The early buildings of the Slave dynasty did not employ true

Islamic building styles and consisted of false domes and false arches. Later, the introduction

of true arches and true domes start to appear, the earliest example is the Alai Darwaza by

the side of QutbMinar. The different religious beliefs are reflected in the mode of

construction and architectural styles. The Islamic style also incorporated many elements

from the traditional Indian style and a compound style emanated. The introduction of

decorative brackets, balconies, pendentive decorations, etc in the architecture is an example

in this regard. The other distinguishing features of Indo-Islamic architecture are the

utilisation of kiosks (chhatris), tall towers (minars) and halfdomed double portals. The

buildings and other edifices were generally decorated richly in geometrical and arabesque

designs. These designs were carved on stone in low relief, cut on plaster, painted or inlaid.

The use of lime as mortar was also a major element distinct from the traditional building

style.

The tomb architecture: The tomb architecture consisted of a domed chamber (hujra), a

cenotaph in its centre with a mihrab on the western wall and the real grave in the underground

chamber. The Mughals added gardens all around the tomb. The Mughal tombs are generally

placed at the centre of a huge garden complex, the latter being sub-divided into square

compartments, the style is known as char-bagh. The Mughals also built large gardens in various

levels and terraces on the char-bagh pattern. They also introduced the double dome system of

dome architecture and the pietra-dura style of inlay decorations. Indo-Islamic architecture into

three broad classes consisting of monuments erected under patronage of the Sultans such as

Qutubudd in Aibak, monuments erected by governors of independent provinces, and landmark

construction of the Mughals. It was around 610 AD that the prophet Muhammad (c. 570 -632)

heard God's message for the first time in Arabia, in the city of Makka. His teachings disseminated

rapidly as Islam grew into a world religion ruling from Spain to the Central Asia by the 8th

century. Its essence is that God is one and every person is equal before God. As Muslims

worshipped with prostrations before God five times a day It was in 1206 that Islamic political

power was established in India for the first time, by Kutb al-Din Aibak. After that, five dynasties

appeared in succession in Delhi and the kings named themselves Sultans of Delhi, so those

dynasties are called 'Delhi Sultanate' as a whole. Their governing people were Turkish or Afghan

nations, but culturally Persia had been ruling Central Asia from Iran, Islamic architecture brought

to India was Persian Islamic architecture too.

THREE CATEGORIES of ARCHITECTURE

At the end of the 12th century when the first Indian mosque was to be constructed in Delhi, India

had been developing stone construction for thousands of years and its technology and aesthetics

had almost reached the stage of perfection. Their religious backgrounds were Buddhism in ancient

times, Hinduism and Jainism in the medieval period. As they were born in the same region and grew

under the same climate, they did not have architectural differences basically. However, Islamic

architecture had grown under a completely different civilization and was alien architecture to India,

having principles and sense of beauty totally different from Indian traditional architecture.

’Sculptural architecture' treats buildings as massive objects and elaborates their sculptural effect as

architectural expression. As seen in temples in Khajuraho, not only are their walls completely

covered with statues of Gods and other sculptures but also the building itself is regarded as an

enormous sculpture as a whole. Their interior spaces are quite narrow and inferior as compared with

its majestic exterior. 'Membranous architecture' or 'Enclosing architecture' that to the contrary

emphasizes their interior spaces or courtyards above all and relegates their exterior forms to second

place. It is represented by Islamic architecture, well-regulated composition and ornament in

geometric order and worship halls as magnificent interior spaces. 'Framework architecture' or

'Trabeated architecture' that consists of a post-and beam frame and its upper roof, not necessarily

requiring demarcation of space with walls. Inside and outside spaces become continuous as a result

of the lack of walls, and its sculptural effect of an exterior form is not so strong. Sculptural

architecture was the first category and membranous architecture as the second category conflicted

with and influenced each other through trial and error. Here Islamic architecture brought from

Persia would transfigure with Indianisation

WOODEN versus MASONRY PRINCIPLES : Wooden architecture was the mainstream for the

ancient India. As wood decreased monumental edifices came to be constructed of stone.

Indians had been totally involved in the trabeated structure and the aesthetics of wood

continued to persist in trabeation, that is to compose buildings with the post and beam

method, treating stone as if it were wood. Since stone is strong against a compressive force

but weak against a tensile force, it is not suitable to be used as a horizontal structural

member (beam and lintel). Indians persisted in the trabeated structure, eventually ended up

with the development of enormous temples. However they could not build a large span of

interior space with that techniques, having to stand many columns like a grove in large halls.

On the other hand, since there was little wood in the Middle East from its inception, they

erected buildings of brick or stone, inventing the masonry structure of arch and dome since

early in the ancient age. The arch is a device to stride a large span by stacking stone pieces

(voussoir) radially along a circular arc, with which one can cover a large hall of dozens of

meters in diameter without columns. Islamic architecture born in the Middle East made

possible the erection of all kind of buildings in the membranous way freely using that

principle of arch and dome.

Quwwat Ul-Islam Mosque in Delhi, India

The first mosque in India, Quwwat al-Islam Mosque in Delhi, was also built as a series of

arches and domes. But Indian craftsmen who did not know the principles of true arch and

true dome and how to construct them used another method of corbelling, which is to pile up

ashlars horizontally, making progressively higher protruding layers. Consequently, most of

those unstable corbelled arches and domes have collapsed, leaving a few arches and

cloisters constructed in a traditional Indian manner intact up to the pre-set. Indian architects

and craftsmen though gradually became versed in the techniques of true arch and dome,

and consequently built mosques, madrasas (schools), palaces, and caravanserais, using them

freely. At long last they were able to realize an outstanding piece of 'membranous

architecture' as a dome structure in diameter of as large as 38m without even one column.

ISLAMIC ARCHITECTURE under THE MUGHALS During the ages of Delhi Sultanate, enough of

the construction techniques of Islamic architecture were transplanted to India even though

some of the roughness remained. Indian Islamic architecture would reach the summit in the

era of the Mughal dynasty from the 16th to 17th centuries. Its first realization was the

Mausoleum of Humayun, the second emperor, which became the prototype of tomb

architecture for subsequent Mughals. Its formation is such that in the center of a huge

'Charbagh' (four quartered garden) a large square platform is built, on which a mausoleum

with identical facades for its four sides

Jami Masjid (Friday Mosque) in Delhi stands symbolically and is capped with a large dome of white

marble. Persian architecture inherited 'Iwan' from ancient palace architecture as a square shape

framing a large arch opening, inside of which is vaulted half-exterior space, and Persian mosques

have four iwans facing each other around a courtyard, that is the form of 'Four Iwans. 'Indians who

loved 'Sculptural architecture,' developed extroverted building in order to enlarge sculptural effects,

settling those four iwans facing in opposite directions, back to back, and covering the central space

with a symbolic dome. This form is more suitable for mausoleums than mosques and it reached the

peak at the magnificent Taj Mahal in Agra. Akbar tried to merge Indian tradition with Islamic

architecture. For buildings in Fatehpur Sikri he constructed as a new capital and his own mausoleum

at Sikandra, he seldom used arches and domes and deliberately used traditional posts and beams in

spite of being Islamic architecture. A pavilion in Fatehpur Sikri protruding even stone slab eaves

protecting against the rainy season looks as if it were wooden structure. Akbar's Tomb at Sikandra

and a Chatri in the Taj Mahal precinct

As for Akbar's mausoleum at Sikandra, it became an unprecedented unique Islamic building, posts

and beams which were stacked up like a four-storied junglegym as 'Framework architecture' on a

high-rise platform. Its components are 'Chatri' (a turret with an apparently heavy roof supported

with four columns. This came to be used as an ornamental element for all sorts of buildings. It is

these chatris that make the strongest impression in the Indo-Islamic architecture. Even in the age of

Shah Jahan who made his buildings revert to Persian style, chatris continued to indicate that the

structures were still following Indian architecture.

3. Ajanta and Ellora are the highest form of cave temple constructions if the ancient India. It was

not only famous for its structural beauty but also the relief sculptures and the fresoe paintings

found on the wall surfaces. The temples of Ajantha are about 29 in number and were dedicated

to Buddha showing the spread of Buddhism and has lot of relief work showing the Buddhist

symbols . Ellora has temples dedicated to Hindusism Jainism and Buddhism. Kailasnath Temple

is the largest structure among all and the

Ajanta site in western India. It is located in Aurangabad district of Maharashtra.

It has 29 caves, including 4 chaitya caves.

It has the large Chaitya-Vihara and is decorated with sculpture and paintings (murals).

Ajanta is the only surviving example of the painting of the first century BCE and the fifth century BCE.

Vihara caves here are unfinished. The important patrons of Ajanta were Varahadeva,

Major paintings are in cave Nos. 1, 2, 16 and 17. Paintings have a lot of typological variations. Figures

in the paintings are heavy like the sculptures of western India.

Cave excavation and painting were a simultaneous process and dating of the paintings follows the

date of the cave excavation.

Almost in all the finished excavations, pictures have been painted, but very few have survived.

Various skin colours in the paintings represent multi-coloured society.

The themes of the paintings are events from the life of Buddha, the Jatakas and Avadanas.

Events happened in the jungle and events happened in the palace are separated by their locations.

Images of Padmapani and Vajrapani are very common in Ajanta.

STUDY OF PAINTING AND SCULPTURE

Padmapani Bodhisattva - late first century CE.

Considered as the masterpiece of INDIAN Art.

The Bodhisattva is holding a Padma (a BLUE Lotus) in his right hand has large shoulders and has

three bents in the body creating a movement.

The other figures revolve around him.

There is grace though the tilt of his head and gesture of his hand. The elegant features, high

forehead, and downcast eyes giving a feel of dignity, and serene meditation.

The modelling is soft and the outlines are merged with the body volume, creating the effects of

three-dimensionality.

Light red, brown, green and blue colours are used in the picture.

On the other side of the image, Vajrapani Bodhisattva has been painted.

He holds a vajra in his right hand and wears a crown.

Bodhisattvas are painted as shrine guardians.

Sapphire indictates royal birth. He wears a pearl and sapphire necklace.

The drapery on the loin area is a striped silk dhoti worn shown in ascetic style.

pictures in cave no.1 are among the best survived paintings of Ajanta.

Mara Vijaya, Ajanta cave no. 1

The theme of Mara Vijaya has been painted in the caves of Ajanta, but only cave no.26 has a

sculptural representation, sculpted on the right wall. The panel shows the image of the Buddha in

the centre, surrounded by Mara’s army a mixed crowd along with his daughters grotesque

dwarfs, surround him to distract him from meditation.

The event is the part of enlightenment and Mara represents desire. It is the personification of mind

which the Buddha went through at the time of enlightenment. The Buddha is shown with his

right hand indicating towards the earth as a witness to his generosity.

Ellora:

Another important cave site located in Aurangabad is Ellora.

It is located 100kms away from Ajanta.

There are 32 Buddhist, Brahmanical and Jain caves.

dating from fifth century CE onwards to eleventh century CE.

It is also unique, i.e., the confluence of many styles at one place.

There are 12 Buddhist caves having many images belonging to Vajrayana Buddhism.

Buddhist caves are big in size and are of a single, double and triple storey.

The triple storey of Ellora is a unique one.

Pillar designs grow from Buddhist caves and when they reach Jain caves (9th century CE), they

become very ornate and the decorative forms gain heavy protrusion.

Most of the caves of Brahamanical faith are dedicated to Shaivism.

The different avatars of Vishnu are also depicted here.

Cave no.16 is known as Kailas Leni or Kailasa temple.

It is a rock cut temple which is carved out of a single rock. It was built in the 8th century CE.

Indian art.

aisle at the back. Pillars, six in each row, divide the hall into a series of smaller chambers. The

roof of the hall has concealed beams supported by stone columns joined together by

capitals. The cave entrance is aligned with the north–south axis, unusual for a Shiva shrine

(normally east–west). The northern entrance to the cave, which has

1,000 steep steps, is flanked by two panels of Shiva dated to the Gupta period. The left panel

depicts Yogishvara (The Lord of Yoga) and the right shows Nataraja (Shiva as the Lord of

Dance). The central Shiva shrine is a Smaller shrines are located at the east and west ends of

on the south wall and is flanked by Ardhanarisvara (a half-man, half-woman representation

of Shiva) on its left and Gangadhara to its right, which denotes the River Ganges descent

from Shiva's matted locks.

hall at strategic locations in exclusive cubicles; these include Kalyanasundaramurti, depicting

Shiva's marriage to the Goddess Parvati, Andhakasuravadamurti or Andhaka-suramardana,

the slaying of the demon Andhaka by Shiva, Shiva-Parvati on Mount Kailash (the abode of

Shiva), and Ravananugraha, depicting the demonking Ravana shaking Kailash. The main cave

blends Chalukyan architectural features such as massive figures of the divinities, guardians,

and square pillars with custom capitals with Gupta artistic characteristics, like the depiction

of mountains and clouds and female hairstyles.)

5. The structure is composed of a cube, 47.5 metres (156ft) on each side, capped by a dome 44

m (144ft) in external diameter. "Eight intersecting arches created by two rotated squares

that create interlocking pendentives" support the dome. At each of the four corners of the

cube, is a dome-capped octagonal tower seven stories high with a staircase inside. The

upper floor of each opens on to a round gallery which surrounds the dome. Inside the

mausoleum hall, is a square podium with steps on each side. In the middle of the podium, a

cenotaph slab on the ground marks the actual grave below, "the only instance of this

practice" in the architecture of the AdilShahi Dynasty. In the middle of the north side, "a

large semi-octagonal bay" protrudes out. With an area of 1,700m2(18,000sqft) the

mausoleum has one of the biggest single chamber spaces in the world. Running around the

inside of the dome is the "Whispering Gallery" where even the softest sound can be heard

on the other side of the mausoleum due to the acoustics of the space.

6. One of the earliest civilizations of the world, emerged during the second half of the third

millennium (Bronze Age) 2500-1500 B.C. The forms of art found from various sites of

civilization include sculptures, seals, pottery, gold ornaments, terracotta figures, etc. Their

delineation of human and animal figures were highly realistic in nature. Modelling of figures

was done in an extremely careful manner. Two major sites of Indus valley civilization along

the River Indus are North – cities of Harrapa and in South – cities of Mohenjadaro. The site

shown is one of the earliest examples of civic planning. Houses markets storage facilities

office, etc. arranged in a grid – like pattern Roads cut across one another in 90 degree angle

and the city was divided into blocks. There was a highly developed drainage system.
