Who was the limping god?

One answer is Hephaestus, or Vulcan (to give his Roman name). When he took sides in an argument between his parents Hera and Zeus (Juno and Jupiter), he was thrown off Olympus. Being immortal, he could not die, but he was injured by the fall, and walked with a limp ever after. Because he was a clever god of the forge, he built servants from metal to assist him and to compensate for his lameness.
