Agamemnon
2. A surname of Zeus, under which he was worshipped at Sparta. (Lycophr. 335, with the Schol.; Eustath.
ad Il. 2.25.) Eustathius thinks that the god derived this name from the resemblance between him and Agamemnon; while others believe that it is a mere epithet signifying the Eternal, from
ἀγὰν and
μένων.
