Hegesippus, also known as Hegesippus the Nazarene, was a Christian writer of the early Church who may, in spite of his Greek name, have been a Jewish convert and certainly wrote against heresies of the Gnostics and of Marcion. The dates that Hegesippus flourished are insecurely fixed by the statement of Eusebius that the death and apotheosis of Antinous (130) occurred in Hegesippus' lifetime, and that he came to Rome under Pope Anicetus and wrote in the time of Pope Eleuterus.
