king of Mycenae, leader of the Greeks in the Trojan War, his name perhaps represents Greek *Aga-med-mon, literally "ruling mightily," from intensifying prefix aga- "very much" + medon "ruler" (from PIE root *med- "take appropriate measures"). But others (Liddell & Scott) connect the second part with menein "to stay, abide, remain," for a literal sense "very steadfast."
