Or Agathos Deos, the "Good God," a divinity in honour of whom the Greeks drank a cup of unmixed wine at the end of every repast. A temple dedicated to him was situated on the road from Megalopolis to Maenalus in Arcadia. Pausanias (viii. 36. § 3) conjectures that the name is a mere epithet of Zeus. (Comp. Lobeck, ad Phrynich. p. 603.)
