Hephaestus was the blacksmith/metalsmith/anythingsmith of Mt. Olympus. This drawing's concept turned out differently than I originally envisioned, but I like it nonetheless.
Zeus was always sleeping with various mortal women; understandably Hera got a little jealous of his promiscuity and all the amazing demigods he was spawning like Hercules. She decided to have an affair so she could have her own child to rival Zeus' beautiful offspring. However, the baby was ugly, so she got mad and hurled it off of Mt. Olympus--Godly maternity I think not. However he landed near the ocean so the sea-nymphs took him. Eventually he came back to Olympus and, ironically, married the goddess of beauty, Aphrodite.
Cool stuff. I've never come across any version of the myth where he gets back at his birth mother...that would've been interesting.
