Agamemnon or Zeus Agamemnon (Gr.Ἀγαμέμνων) was a cultic epithet of the Greek godZeus,[1] under which he was worshiped at Sparta.[2][3][4][5] Some writers, such as Eustathius, thought that the god derived this name from the resemblance between him and the Greek hero Agamemnon; others that Zeus Agamemnon was merely a synecdoche glorifying the hero, not the god.[6] Still others believed it to be a mere epithet signifying the eternal, from agan (ἀγὰν) and menon (μένων).
