catacomb: [17] Catacomb derives from the name of an underground cemetary in ancient Rome, the Coemetērium Catacumbas, beneath the Basilica of St Sebastian near the Appian Way. It is said that the bodies of St Peter and St Paul were deposited in or near its subterranean passages. The word’s more general application to any underground labyrinth dates from the 17th century. The original significance of Latin Catacumbas is not known.
