Jerome’s version of the Chron. agrees with this passage in assigning eight months to the episcopate of Eutychianus, while the Armenian gives him only two months. The Liberian catalogue, however, gives eight years eleven months and three days; and Lipsius accepts these figures as correct, putting his accession on the fifth of January, 275, and his death on the eighth of December, 283. Jerome puts his accession in the fifth year of Probus, which is wide of the mark, the Armenian in the second year, which is also too late by about two years. Lipsius explains the eight months of the Church History and the Chron. as a change, in their original source, of years to mouths. The present error makes up in part for the error in chap. 27, where Xystus is given eleven years instead of eleven months. Eutychianus was not a martyr, but was buried, according to the Liberian catalogue, in the Catacombs of St. Calixtus, a statement which has been confirmed by the discovery of a stone bearing his name.
