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.
Gaia (mythology) In Greek mythology, Gaia ( or from Ancient Greek Γαῖα , a poetical form of Γῆ "Gē", "land" or "earth"), also spelled Gaea, is the personification of the Earth and one of the Greek primordial deities. Gaia is the ancestral mother of all life: the primal Mother Earth goddess. She is the immediate parent of Uranus (the sky), from whose sexual union she bore the Titans (themselves parents of many of the Olympian gods) and the Giants, and of Pontus (the sea), from whose union she bore the primordial sea gods. Her equivalent in the Roman pantheon was Terra.
