安提柯一世
Ptolemy is the English form of the Ancient Greek name Πτολεμαῖος ("Ptolemaios"), a derivative of πτόλεμος, an Epic form of πόλεμος 'war'. A nephew of Antigonus I Monophthalmus was called "Polemaeus", the normal form of the adjective. "Ptolemaios" is first attested in Homer's Iliad and is the name of an Achaean warrior, son of Piraeus, father of Eurymedon.
