3. Metis. Metis was Zeus's first wife. Her name holds two meanings: widsom and cunning. Her name originally meant magical cunning. It was told that her children with Zeus would grow up to overthrow him, which led to Zeus swallowing her in a failed attempt to prevent this from occcurring.

4. Hephaestus. Hephaestus was well-known for being a blacksmith. He is associated with tongs, a hammer, and an anvil. In one story, it is said that Hera gave birth to him in order to get revenge for her exclusion from Athena's birth. He was exiled from Olympus, but was able to return.
