Nebuchadnezzar

Wolfram says that King Nebuchadnezzar of Babylon was the maternal uncle of King Pompeius of Babylon - one of two brothers who fought with the Baruc of Baghdad and who Perceval’s father Gahmuret died fighting against.

If Wolfram intends to indicate the legendary King Nebuchadnezzar who ruled from 605 b.c. to 562b.c. - and it seems he does - Pompeius must have been a truly ancient man.
