(Redirected from Baptistry)
In
Christian architecture the 'baptistery' or 'baptistry' (
Latin ''baptisterium'') is the separate centrally-planned structure surrounding the
baptismal font. The baptistery may be incorporated within the body of a church or
cathedral and be provided with an altar as a chapel. In the early
Christian Church, the
catechumens were instructed and the
sacrament of
baptism was administered in the baptistery.
The sacramental importance and sometimes architectural splendor of the baptistry reflect the importance of
baptism to Christians. The octagonal plan of the
Lateran Baptistery, the first structure expressly built as a baptistry, provided a widely-followed model, which might be twelve-sided, or even circular as at Pisa. In a
narthex or ante-room the catechumens were instructed and made their
confession of faith before baptism. The main interior space centered upon the
baptismal font (''piscina''), in which those to be baptized were immersed thrice. Three steps led down to the floor of the font, and over it might be suspended a gold or silver dove. The iconography of
frescos or
mosaics on the walls were commonly of the scenes in the life of
Saint John the Baptist. The font was at first always of stone, but latterly metals were often used.

The Lateran baptistery
The Lateran baptistery's font was fed by a natural spring. When the site had been the palatial dwelling of the Laterani, before Constantine presented it to Bishop Miltiades, the spring formed the water source for the numerous occupants of the ''domus.'' It will be quickly apprehended that as the requirements for Christian baptisteries expanded,
Christianization of sacred pagan springs presented natural opportunities.
Cassiodorus, in a letter written in A.D. 527, described a fair held at a former pagan shrine of
Leucothea, in the still culturally Greek region of south Italy, which had been Christianized by converting it to a baptistery (''Variae'' 8.33). In a
paper read in 1999, Samuel J. Barnish drew examples of the transition from miraculous springs to baptisteries from
Gregory of Tours (died ''c.'' 594) and
Maximus, bishop of Turin (died ''c.'' 466).
Baptisteries belong to a period of the church when great numbers of adult catechumens were baptized, and when immersion was the rule. We find little or no trace of them before
Constantine made
Christianity the
state religion, i.e. before the
4th century; and as early as the
6th century the baptismal font was built in the
porch of the church and then in the church itself. After the
9th century, with infant baptism increasingly the rule, few baptisteries were built. Some of the older baptisteries were very large, so large that we hear of councils and
synods being held in them. It was necessary to make them large, because in the early Church it was customary for the bishop to baptize all the catechumens in his
diocese (and so baptisteries are commonly found attached to the
cathedral and not to the
parish churches), and also because the rite was performed only thrice in the year.
During the months when there were no baptisms the baptistery doors were sealed with the
bishop's
seal, a method of controlling the orthodoxy of all baptism in the diocese. Some baptisteries were divided into two parts to separate the sexes; sometimes the church had two baptisteries, one for each sex. A
fireplace was often provided to warm the neophytes after immersion.

The baptistry of Florence
Though baptisteries were forbidden to be used as
burial-places by the
Council of Auxerre (578) they were not uncommonly used as such. The Florentine
Antipope John XXIII was buried in the
Baptistery facing
Florence's Duomo with great ceremony and a tomb erected. Many of the early
archbishops of Canterbury were buried in the baptistery at Canterbury.
Baptisteries, we find from the records of early councils, were first built and used to correct the evils arising from the practice of private baptism. As soon as Christianity made such progress that baptism became the rule, and as soon as immersion gave place to sprinkling, the ancient baptisteries were no longer necessary. They are still in general use, however, in Florence and Pisa.
The baptistery of the
Lateran must be the earliest ecclesiastical building still in use. (''Main article:
Lateran Baptistery.'') A large part of it remains as built by Constantine. The central area, where is the basin of the font, is an octagon around which stand eight
porphyry columns, with
marble capitals and
entablature of classical form; outside these are an
ambulatory and outer walls forming a larger octagon. Attached to one side, towards the Lateran basilica, is a fine porch with two noble porphyry columns and richly carved capitals, bases and entablatures. The circular church of
Santa Costanza, also of the 4th century, served as a baptistery and contained the tomb of the daughter of Constantine. This is a remarkably perfect structure with a central dome, columns and mosaics of classical fashion. Two side niches contain the earliest known mosaics of distinctively Christian subjects. In one is represented
Moses receiving the Old Law, in the other
Christ delivers to
Saint Peter the New Law charter sealed with the XP monogram.
The earliest surviving structure that was used as a baptistry is the tomb-like baptistry at
Dura-Europas [1]. Another baptistery of the earliest times has been excavated at
Aquileia. Ruins of an early baptistery have also been found at
Salona. At
Ravenna exist two famous baptisteries encrusted with fine
mosaics, one of them built in the middle of the
5th century, and the other in the 6th. To the latter date also belongs a large baptistery decorated with mosaics at
Naples.
In the East the metropolitan baptistery at Constantinople still stands at the side of the mosque which was once the patriarchal
Church of Saint Sophia; and many others, in
Syria, have been made known to us by recent researches, as also have some belonging to the churches of
North Africa. In
France the most famous early baptistery is
Saint Jean at
Poitiers, and other early examples exist at
Riez,
Fréjus and
Aix-en-Provence. In
England, a detached baptistery is known to have been associated with
Canterbury Cathedral.
