There were actually two Maeras. The first was the daughter of Protus. This Maera was one of the cold Artemis' companions - her bad luck, in this case. For Zeus fell in love, and decided to pursue her. Artemis was NOT about that, and killed Maera (in that god-like logic, that I will never understand). Anyway, in the other version she is just a daughter of Atlas.n
Maia was the oldest of the Pleiades, and she was chillin' in this cave in Arcadia when Zeus came and, skipping what happened in between, she bore Hermes (my favorite masculine God), and raised him in that cave, far away from Hera's jealous eyes. After Hermes' grows up, we don't hear much more about her.
Melissa is greek for "honey bee" and she was the name of Artemis as the moon goddess and the goddess who took suffering away from mothers giving birth. There were also a bunch of priestesses and nymphs with the same name, but you'll have to check on their own pages.n
Metis was another Titaness. She was the Goddess of Prudence, but there is a rather unprudent story about her that tells about the birth of Athena. Metis ends up living inside Zeus' head and giving him advice from there. Her name meant Cunning and she was the personification of it as well as its Goddess. She was also the one who discovered (created) the potion that caused Cronos to vomit up the six OGs, (to all y'all who understand the joke, thank you for not being either too old or too young). Anyway, her daughter eventually burst from Zeus' head fully formed - and fully clothed in the armor her that Metis made for her - but Metis apparently had gotten comfortable in her new pad and stayed there. That painting is of Athena because I can't seem to track one of Metis down. If you are interested in learning more about Metis, I recommend you skip her myths and go straight to the heroes most famous for employing her: Odysseus and Penelope. n
