Hera is totally my favorite goddess.
I think she gets a bum rap in a lot of the stories, especially in the myths of Heracles. Anyone who's studied the ancient world knows that Hera was an incredibly important goddess; Zeus himself seems to have been overshadowed in actual cult back in the day. Starting with Homer and later chroniclers she begins to be depicted as the jealous, shrewish wife; Homer was sexist.
Heracles, incidentally, translates to "The Glory of Hera", which will be the name of volume of The Olympians that deals with Hera. I'm going to explore Hera's relationship to the heroes, both antagonistic (Heracles) and protective(Jason), as well as a look into what it's like to be married to the most infamous philanderer in mythology. I think it should be very illuminating, and more than a little redemptive for a misunderstood goddess.
For Hera's appearance, I wanted her to be extremely beautiful (Zeus did choose her as his queen) and also a little arch and severe. To that end, I gave her the tightly-drawn back hair, evocative of a peacock's crest. The peacock is one of her symbols in ancient depictions, so I additionally wanted an echo of that.
