You may not know it, but you already love Iris. Why? Because she's the goddess of rainbows. And seriously, how can you not like rainbows? For a while, everybody said Iris was a virgin goddess, but she ended up marrying Zephyrus, the West Wind. Sounds like a match made in… Olympus.

In addition to her colorful job as rainbow goddess, Iris is also a messenger of the gods. That means she spends most of her days winging down her multicolored bridge on her golden wings, making sure the mortal world gets an earful of what Olympus has to say. And because her rainbows span from the sea to the sky, she is able to fly back and forth, gathering seawater in a pitcher and refill the clouds with rain. Pretty impressive stuff.
