A ruler from Babylon and brother of Ipomidon in Wolframís Parzival.

The brothersí ancestral city of Niniveh was seized by the Baruc of Baghdad. In response, Pompeius and Ipomidon invaded the Barucís country, where they had to contend with Gahmuret, Percevalís father, who was serving the Baruc.

Wolfram says that Pompeiusís maternal uncle was King Nebuchadnezzar.
