Agamemnon was a hero in Greek mythology, leader of the Greek army which conquered Troy.
Henry Janeway remarked in December 2000, that the great Greek heroes like Hercules, Agamemnon and Odysseus had all been raised by single parents. (VOY: "11:59")
According to Apollo, Agamemnon was "proud and arrogant" and originally defied him, but after Apollo struck him this changed. Apollo considered Captain Kirk to be the same way when the USS Enterprise found Apollo in 2267. (TOS: "Who Mourns for Adonais?")
