Passio sanctorum Petri et Pauli no relation Linus pope
Origins
The Passio, which appears in numerous medieval manuscripts, was known to Jacobus de Voragine who noted in his vita of the Apostle Peter, "His martyrdom wrote Marcellus, Linus pope, Hegesippus, and Leo the pope." There are two Old English analogues, Ælfric's Passio Apostolorum Petri et Pauli  and the anonymous Blickling Homily 15, Spel Be Petrus & Paulus.The work appears to have been based on the Acts of Peter, with the addition of Paul's presence where before it was only Peter's. The work is dated to around 450 to 550. Latin as well as Greek versions survive, with the latter usually being longer. The Latin versions sometimes end with "I, Marcellus, have written what I saw." This Marcellus is identified as a disciple of Simon Magus, who lived in the 1st century. Because of this obvious anachronism, since the text is clearly written centuries later, scholars have dubbed him Pseudo-Marcellus.
