s of
Calixtus and Domitilla, was discovered a crypt with frescoes and the
sanctuary of a martyr: it is thought that this, rather than a
neighbouring crypt brought to light in 1897, may prove to be the
sepulchral crypt of SS. Marcus and Marcellianus. In a cubiculum leading
out of a gallery in the vicinity there was also discovered an
interesting impression in plaster of an inscription of the mother of
Pope Damasus, beginning:

HIC DAMASI MATER POSVIT LAVREN[TIA MEMBRA].

In the same year building operations in the Via di Sant' Onofrio
revealed the presence of catacombs beneath the foundations: examination
of the _loculi_ showed that no martyrs or illustrious persons were
buried here.

In 1903 a new cemetery with frescoes came to light on the Via Latina,
considered by Marucchi to have belonged to a heretical sect. In the same
year the Jewish cemetery on the Via Portuense, known to Bosio but since
forgotten, was rediscovered. The subterranean basilica of SS. Felix and
Adauctus, discovered by Boldetti and afterwards choked up with ruins,
was cleared again: the crypt, begun by Damasus and enlarged by Siricius,
contains frescoes of the 6th-7th centuries.

A good plan of the catacombs at Albano (at the 15th milestone of the
Appian way), discovered by Boldetti and described by De Rossi, has been
published by Marucchi (_Nuovo Bulletino di archeologia cristiana_, 1902,
pp. 89 ff.). In 1904 a small subterranean cemetery was discovered at
Anagnia. Catacombs have also been recently discovered on the site of
Hadrumetum near Sousse in Tunisia. (+ W. R. B.; O. M. D.)

AUTHORITIES.--The classical work on the catacombs of Rome is G.B. De
Rossi's _Roma sotterranea_, on which most of the accounts in other
languages than Italian have been based. The fine volume by Mgr.
Wilpert, _Le Pitture delle catacombe romane_ (Rome, 1903), in which
all the important frescoes are reproduced in colours, is to be
regarded as an addition to the _Roma sotterranea_. All new
discoveries made by the active _Commissione di archeologia sacra_ are
chronicled with as little delay as possible in the _Nuovo Bulletino de
archeologia cristiana_ published in Rome.

The most recent accounts of the catacombs are to be found in the
following books:--Armellini, _Gli Antichi Cimiteri cristiani di Roma e
d' Italia_ (Rome, 1893); O. Marucchi, _Le Catacombe romane_ (Rome,
1903; also translated into French), _Manuale di epigrafia cristiana
