This is a subsidiary post of Lists Earlier Than the Fourth Century.
Until Sundberg and Hahneman, the Muratorian Fragment was considered of late second century vintage, originating in or around Rome. They have argued for a fourth century dating (ca. 350-375), originating in Syria or elsewhere in the East, and have over time swayed other scholars, such as McDonald and Gamble.
