Chronographer of a.d.
354. A modern title given to a state directory compiled from fragments of MSS. Its chronicled entries cease at 354, when it might have been compiled by Dionysius Philocalus, the later calligrapher of Damasus I, for the use of Christians at Rome. It contains an illustrated state calendar (Roman holidays); a register of the consuls from a.u.c. 245 to a.d. 354; a list of city prefects from 254 to 354; a description of the fourteen districts of Rome; Easter tables from 312 to 354 (with an extension to 410); a chronicle of the world, called Chronica Horosii, which is a Latin version and extension to a.d. 334 of the chronicle of Hippolytus; a chronicle of the city to the death of Licinius (324/5); anniversaries of Roman bishops from 255 to 352 (= Depositio Episcoporum); the oldest existing list of martyrs (= Depositio Martyrum); a list of bishops of Rome from Peter to Liberius (352-66), defining the length of their episcopates (= ). This differs significantly from the early list in Irenaeus, which distinguishes the apostles Peter and Paul from the first bishop, Linus.
