Stevenson, since dead, discovered in 1896 a small subterranean basilica in the catacomb of Santi Pietro e Marcellino on the Via Labicana, with pious acclamations on the plaster similar to those in the Papal crypt in St Calixtus.
This catacomb contains an unquestionable example of a church, divided into a nave and chancel, with a rude stone altar and bishop's seat behind it.
In 5890 the first Christian catacomb bearing a distinct date (491) was discovered.
19, 20), from Agincourt, of the catacomb and of one of the circular halls, show how widely this cemetery differs in arrangement from the Roman catacombs.
At Taormina in Sicily is a Saracenic catacomb, also Taornlna.
