Stolen from Wiki as I am not Hellenistic expert.

Antiochus IV Epiphanes
He assumed divine epithets, which no other Hellenistic king had done, such as Theos Epiphanes("God Manifest") and after his defeat of Egypt, Nikephoros("Bearer of Victory")[2]. But his often eccentric behavior, capricious actions and even insanity led some of his contemporaries to call him Epimanes ("The Mad One"), a word play off of his title Epiphanes.

He was the one invading Ptolomaic Egypt to be met on the way to Alexrandria by an old Roman and his cane...

Easier to be Roman, campaign somewhere and get/take that name, Scipio Africanus most famously.
