Astrolabe - Celestial navigation
an instrument used to make astronomical measurements, typically of the altitudes of celestial bodies, and in navigation for calculating latitude, before the development of the sextant.
Our Astrological perspective
! Our universe ! The fixed stars that surround our solar system
the constellations, the moving signs ! This solar system, the earth in the solar system ! The sun’s movement along the ecliptic plane ! The movement of celestial bodies and planets, ! The rising and setting of stars and constellations
16
88 constellations - one path
21
Fixed stars are all measured by ecliptic plane eg: Sun is conjunct Canopus, Canopus is not on the ecliptic
The Great Circles
! A Great Circle - is any circle whose plane passes through the centre of the Earth
! Great Circles important to astrologyCelestial Equator*EclipticHorizon Prime MeridianPrime Vertical*
26
Ecliptic
! A great circle on the celestial sphere representing the sun's apparent path during the year
! “Apparent“ - Earth is moving around Sun, not the other way around, as seen from our perspective
! Called ecliptic because lunar and solar eclipses can only occur when the moon crosses this pathway of the sun.
! Ecliptic longitude or celestial longitude measures the distance of an object along the ecliptic
! 0° ecliptic longitude is the position of the Sun at the vernal equinox 0° Aries ! 0° to 360°, all signs divided equally into 30° along ecliptic ! Tilted at 23° from equator, the Sun’s movement reaches it peak movement at
the tropics of Cancer(N) and Capricorn(S), for the Solstices, and the celestial Equator at Equinoxes
27
Equator, Celestial Equator
! Equator ! Celestial Equator
-Earth’s equator extended into space-A great circle always perpendicular, to Earth’s polar axis- ecliptic intersects the celestial equator at equinoxes 0° Aries- 0° Libra
29
Horizon
! Horizon is a plane specific to a given location Earth ! Dividing the visible hemisphere from the invisible ! The apparent horizon is a plane tangent to the Earth’s surface at a
specific location ! Where the Horizon and Ecliptic cross, this is known as the
Ascendent and the Descendent ! Ascendant - what rises in east ! Descendant - what sets in the west
30
Prime Vertical and Prime Meridian
! Prime Vertical - The great circle that intersects the horizon, East and west passing through the zenith and nadir at right angles perpendicular 90 ° the horizon,
! The Prime/Local Meridian This intersection with the Ecliptic creates the MC- IC axisMeridian; MC / IC * - Medium Coeli, MC - Middle sky, Midheaven, - Imum Coeli, IC - bottom sky - point at which local meridian intersects with the ecliptic - north and south- Changeable depends on your location
31
Sidereal and Tropical Astrology
! Sidereal - star position, constellation, fixed star- Sidereal Aries begins15th April
! Tropical - zodiac begins with Sun position at vernal equinox - 0 Aries begins, 12 signs of 30 degrees each follow - 12 x 30 =360°-Tropical Aries begins 20th -21st March,
! Now - 25 days/ 25° difference ! Due to Precession of the Equinox -
37
Precession of the Equinox
38
Current Aries Point is at approx 5°
Pisces/constellation
Age of Aquarius begins when Zero Aries point moves into sign of Aquarius
When signs and constellations will overlap be of out of alignment by 30° each(currently 25°)
Constellational zodiac
The wobble
Precession of the Equinox
Both aligned at approx 200 ACE Constellations are not 30° each, vary in size (can’t) be divided into 30 degrees
each Precession moves the Vernal Equinox point against backdrop of stars - 1°
backwards along the ecliptic/zodiac every 72 years, opposite to motion of Sun Age of Pisces to Age of Aquarius Moving the signs out of alignment with the original constellations by 25° Example today Sun at 12° Pisces Tropical - Sidereal /17° Aquarius By moving backwards/ tropical zodiac is nearly a whole sign in fornt of sidereal Movement - credited to Hipparchus and Ptolemy in approx 127 ACE
39
44
-Age of Aquarius 5 degrees away 72° x 5 = 360 years awaybegins approx - 2374 ACE
-According to tropical astrology - of signs being 30 degrees each
-Many variations- orbs(era of influence), many theories exist
The Great Year - 26,000 years
! One complete cycle of moving Aries point/Equinox point around ecliptic ! Zodiacal Ages ! Age of Pisces, Age of Aries, Age of Taurus ! Age of Aquarius, ! 26,000 approx years divided by 12 signs = 2160 years each ! The Platonic Year
