Yeah, Mercury is just a godly guy. At some point, humans started to discover other bodies in their night sky, the other planets, and started to give them names. A lot of them are named after gods. Some deities have jobs revolving around other celestial bodies, Apollo drives the sun across the sky, and Artemis the moon. Having ridden in the sun chariot, I can attest that it's kind of literal. However it works that a guy could run the sun while, scientifically, the earth rotates around it.
