Pope Saint Pontian or Pontianus, was pope from 21 July 230 to 29 September 235. A little more is known of Pontian than his predecessors, apparently from a lost papal chronicle that was available to the compiler of the Liberian Catalogue of bishops of Rome, made in the fourth century (Catholic Encyclopedia). His feast day was 19 November, but he is now celebrated jointly with his erstwhile adversary and rival, Hippolytus of Rome, on 13 August.
