buried there. The latter detail is evidently an error, for the fourth-century Roman calendar of feasts says that Pope Felix was interred in the Catacomb of Callixtus on the Via Appia. The statement of the Liber Pontificalis concerning the pope's martyrdom results obviously from a confusion with a Roman martyr of the same name buried on the Via Aurelia, and over whose grave a church was built. In the Roman "Feriale" or calendar of feasts, referred to above, the name of Felix occurs in the list of Roman bishops (Depositio episcoporum), and not in that of the martyrs. According to the above-mentioned detail of the Depositio episcoporum, Felix was interred in the catacomb of Callixtus on 30 December, "III Kal. Jan." (third day to the calends of January) in the Roman dating system. Saint Felix I is mentioned as Pope and Martyr, with a simple feast, on 30 May. This date, given in the Liber Pontificalis as that of his death (III Kal. Jun.), is probably an error which could easily occur through a transcriber writing "Jun." for "Jan." This error persisted in the General Roman Calendar until 1969 (see General Roman Calendar of 1960), by which time the mention of Saint Felix I was reduced to a commemoration in the weekday Mass by decision of Pope Pius XII (see General Roman Calendar of Pope Pius XII). Thereafter, the feast of Saint Felix I, no longer mentioned in the General Roman Calendar, is celebrated on his true day of death, 30 December, and without the qualification of "martyr". According to more recent studies, the oldest liturgical books indicate that the saint honoured on 30 May was a little-known martyr buried on the Via Aurelia, who was mistakenly identified with Pope Felix I, an error similar to but less curious than the identification in the liturgical books, until the mid-1950s, of the martyr saint celebrated on 30 July with the antipope Felix II.
