Vulcan carefully shut this precious coal in a clam shell and took it back to his underwater grotto and made a fire with it. On the first day after, Vulcan stared at this fire for hours on end. On the second day, he discovered that when he made the fire hotter with bellows, certain stones sweated iron, silver or gold. On the third day he beat the cooled metal into shapes: bracelets, chains, swords and shields. Vulcan made pearl-handled knives and spoons for his foster mother, he made a silver chariot for himself, and bridles so that seahorses could transport him quickly. He even made slave-girls of gold to wait on him and do his bidding. From then on, Vulcan and Thetis lived like royalty.
