Archelaus , supposed bp. of Carchar (perhaps Carrhoe Harrom in Mesopotamia). A work is attributed to him called Acta Disputationis Archel. Ep. Mesop. et Manetis haeresiarchae. It is extant in a Latin translation from a Greek text, but some think the Greek is derived from a Syriac original. The author was probably (cf. Phot. Cod. 85) a certain Hegemonius. The disputation and Archelaus himself seem to be fictitious; but the work affords valuable information respecting the Manichean system (cf. Bardenhewer, 1908, pp. 208–269).
