A ruler from Babylon and brother of Pompeius.
The brothers’ ancestral city of Niniveh was seized by the Baruc of Baghdad. In response, Ipomidon and Pompeius invaded the Baruc’s country, where they had to contend with Gahmuret, Perceval’s father, who was serving the Baruc.
In their second invasion, Ipomidon killed Gahmuret in combat.
