The Acts of Peter were originally composed in
Koine Greek during the second half of the 2nd century, probably in
Asia Minor. The style of the Acts' writing is quite similar to that of four other apocryphal Acts –
Acts of Andrew,
Acts of John,
Acts of Paul, and
Acts of Thomas. For this reason, all five of these works were traditionally attributed to a single author;
Photios I () identified this author as
Leucius Charinus.
Epiphanius () had earlier identified Leucius as a companion of
John the Apostle. The
Manicheans are believed to have collected these five apocryphals Acts into a single corpus by the end of the 4th century. Despite this, the works are still frequently referred to as the "Manichean Acts of Leucius Charinus", or simply the "Leucian Acts". The earliest extant manuscript of the Acts of Peter is a
Late Latin translation contained in the
Codex Vercellensis, which is believed to be the earliest manuscript of the . This
codex is preserved in the Capitulary Library of the
Vercelli Cathedral. The chapters describing
Peter's crucifixion (XXXIII–XLI) are preserved separately as 'Martyrdom of the Holy Apostle Peter' in various manuscripts in Latin,
Greek,
Coptic,
Slavonic,
Syriac,
Ethiopic,
Armenian, and
Arabic. It has been proposed that the martyrdom account was an earlier, separate text to which the preceding chapters were affixed. ==Content==
