It wasn't a god. According to some accounts, Perseus passed by Atlas on his way to return the sack given to him by the Hesperides. Atlas tried to shoo him away, but Perseus, still heady with his victory, revealed Medusa's head to the Titan, turning him into stone (i.e. the Atlas Mountains of North Africa).
That account, though, doesn't jive with the later account of Heracles, which has the hero interacting with a perfectly mobile and not-at-all-stone Atlas. A more reasonable end to the tale is that after bearing Atlas' burden himself, Heracles decided to help the Titan by building the Pillars of Heracles, thus relieving the Titan of his burden.
