Dating the Catacombs of Rome

The Christian catacombs of Rome were recorded in church annals and remained alive in tradition, but the Jewish catacombs seem to have been all but forgotten by the early Middle Ages. Since Bosio's discovery of a Jewish catacomb on the Monteverde in 1602, little ancient literary documentation of the Jewish cemeteries has been recovered, and hardly any useful epigraphic dates are available to researchers. Even so, scholars continue to put forth new theories about the dating of the Jewish catacombs. Among the few chronological indicators available from the sites themselves have been the markers' marks on the Roman bricks used in their construction. The marks give clues as to the dates when the bricks were produced, but the cannot be relied upon to furnish exact dates, because the bricks could have been reused even long after their manufacture.(1)

It is difficult as well to establish firm dates based on Latin inscriptions inside the catacombs because the styles of Latin carving often persisted for considerable periods, and some inscriptions might not have ben set in place until well after the earliest use of a catacomb.(2) Thus, neither brick stamps nor epigraphy are considered chronologically definitive by today's scholars.

Other clues for dating have been sought in styles of construction and painted decoration, epigraphic names, coins, glassware and its workmanship, and the shape, design, color, and manufacture of the clay lamps found in the catacombs.(3) Even so, it must be borne in mind that any chronology advanced for the catacombs based on material finds will be affected by accidents of discovery, the recycling of materials, the perpetuation of older styles and techniques, and fragmentation and deterioration, all of which can lead to distorted conclusions.

Rutgers has pointed out, the practice of stamping bricks did not begin until after the reign of Augustus (27 BCE-14 CE): Rutgers, The Jews in Late Ancient Rome: Evidence of Cultural Interaction in the Roman Diaspora, Leiden-New York: Brill, 1995, p. 98.
