EARLY CHRISTIAN CHURCH ARCHITECTRURE
1) Propylaeum- the entrance building of a sacred precinct, whether
church or imperial palace.
2) Atrium- the forecourt of a church; as a rule enveloped by four
colonnaded porticoes.
3) Narthex- the entrance hall or porch proceeding the nave of a
church.
4) Nave- the great central space in a church. In longitudinal
churches, it extends from the entrance to the apse (or only to the
crossing if the church has one) and is usually flanked by side aisles.
5) Aisle- one of the corridors running parallel to the nave of a church
and separated from it by an arcade or colonnade.
6) Crossing- the area in a church where the transept and the nave
intersect.
7) Transept- in a cruciform church, the whole arm set at right angles to
the nave.
8) Apse- a recess, sometimes rectangular but usually semicircular, in the
wall at the end of a Roman basilica or Christian church. The apse in the
Roman basilica frequently contained an image of the Emperor and was
where the magistrate dispensed laws. In the Early Christian basilica, the
apses contained the "cathedra" or throne of the bishop and the altar.
9) Clerestory- a clear story, i.e. a row of windows in the upper part of a
wall. In churches, the clerestory windows above the roofs of the side
aisles permit direct illumination of the nave
The term early Christian architecture refers to the architecture of the early
Christian churches of the roman era
This is further divided into two types; the basilica church and the alternative
church plans
With Christianity accepted as a state religion in Rome and expanding in
influence, it became necessary for architecture to respond to the space demands
of the new religion
A building used for Christian worship had to provide a path for the processional
entry and exit of the clergy, an alter area, where the clergy celebrated mass, a
space for the segregation of the clergy from congregation during the procession
and communion
The architecture of the church that developed was not a completely new
style, but the use of available Roman forms to satisfy a new program need
The form chosen for the early church was the Roman basilica
It was suitable for use as a church with no serious modification and it could
be easily and rapidly built at low cost
The Basilica was also preferred because of the emphasis on participation in
mass.
The most common form of the early churches had a rectangular hall with a
timber trussed roof
It also had one or two isles on each side of a central nave and an apse at one
end facing the principal entrance located at the other end
Most of the early churches had clerestory lighting
Clerestory windows were developed to give light to the central part of the
interior
Gradually, the clerestory windows became a symbol of the transcendence
and grace of god
St Peter was the most important of the basilica churches built by Constantine
The church has a triple entrance gate leading to an atrium
The Basilica had a wooden roof of interlocking rafters
The nave did not lead directly to the apse but instead ends in a transverse
space that is as high as the naveThe nave terminated in a triumphal arch that
framed the curve of the apse
S. Peters, Rome AD 333
Some of the early churches were built over the tomb of martyrs and are
known as martyrium
St Peters is one of the earliest and most important of the matyrium churches
It was built over what was believed to be the tomb of Saint Peter who was a
disciple of Jesus
