Hegemonius (Greek: Ηγεμόνιος) or Pseudo-Hegemonius was a 4th-century Christian who is known only from his presumed authorship of the Acta Archelai,[1] a work on Manichaeism preserved only in Latin.
[2] "Traditionally attributed to Hegemonius, the Acta Archelai is the oldest and most significant anti-Manichaean polemical text.
The Acta gives a fictional account of a debate between Mani and Archelaus, the Christian bishop of the city of Carchar in Roman Mesopotamia as well as an important summary of his teaching on cosmogony and a highly polemical version of Mani's life.
The work would later exercise enormous influence on anti-Manichaean writings in both Late Antiquity and Middle Ages.
"[3] A Latin edition Acta Disputationis Archelai, Episcopi Mesopotamia et Manetis Haresiarch was published by Lorenzo Alessandro Zaccagni, librarian of the Vatican Library, in Collectanea monumentorum veterum Ecclesiae graecae et latinae.
