A ruler from Babylon and brother of Ipomidon in Wolfram’s Parzival.
The brothers’ ancestral city of Niniveh was seized by the Baruc of Baghdad. In response, Pompeius and Ipomidon invaded the Baruc’s country, where they had to contend with Gahmuret, Perceval’s father, who was serving the Baruc.
Wolfram says that Pompeius’s maternal uncle was King Nebuchadnezzar.
