Hephaestus, the god of fire, was known to be a great blacksmith who created wondrous, magnificent works. Some of them were the golden chariot and the golden cups for the sun-god Helios, a golden shield for the heroes Heracles, Achilles and Diomedes, the scepter and the throne of Zeus, as well as bows for the twin gods Artemis and Apollo.
The Great "Robots" of Hephaestus
Up on Mount Olympus, Hephaestus built a bronze palace for the gods and crafted golden robot-like statues to serve him. Those statues looked similar to teenagers and had their own voice, strength and thought.
Furthermore, Hephaestus created:
-two mechanical, immortal dogs out of gold and silver in order to guard the palace of Alcinous,
-automatic tables that obeyed the voices of the gods, who called the tables to provide them with food and drink,
-two wild bulls with bronze feet, with voices coming out of their nostrils and fire coming out of their mouths...
...and the speedy giant Talos, whom he gave to King Minos in order to guard the island of Crete and oversee the implementation of laws.
