(Μόνοικος), a surname of Heracles, signifying the god who lives solitary, perhaps because he alone was worshipped in the temples dedicated to him. (Strab. iv. p.202; Verg. A. 6.831; Plut. Quaest. Rom. 87.) In Liguria there was a temple called Monoecus (now Monaco; Strab. Virg. ll. cc. ; Tac. Hist. 3.42; Steph. Byz. s. v.).
