Metis (mythology) Metis (Μῆτις, "wisdom," "skill," or "craft"), in ancient Greek religion, was a mythological character belonging to the Titan generation. Like several primordial figures, she was an Oceanid, in the sense that Metis was born of Oceanus and his sister Tethys, of an earlier age than Zeus and his siblings. Metis was the first great spouse of Zeus, and also his cousin. Zeus is himself titled "Mêtieta", "the wise counsellor," in the Homeric poems.
Euterpe In Greek mythology, Euterpe ( ; Greek: Eὐτέρπη , ] , ] ; "rejoicing well" or "delight" from Ancient Greek εὖ 'well' + τέρπειν "terpein" 'to please') was one of the Muses, the daughters of Mnemosyne, fathered by Zeus. Called the "Giver of delight", when later poets assigned roles to each of the Muses, she was the muse of music. In late Classical times she was named muse of lyric poetry and depicted holding a flute. A few say she invented the "aulos" or double-flute, though most mythographers credit Marsyas with its invention.
