Hephaestus
Automatons

According to Homer, Hephaestus built automatons of metal to work for him or others. This included tripods with golden wheels, able to move at his wish in and out the assembly hall of the celestials; and servant "handmaidens wrought of gold in the semblance of living maids", in them was "understanding in their hearts, and speech and strength", gift of the gods. They moved to support Hephaestus while walking. And he put golden and silver lions and dogs at the entrance of the palace of Alkinoos in such a way that they could bite the invaders, guard dogs that didn't age nor perish.

A similar golden dog (Κυων Χρυσεος) was set by Rhea to guard the infant Zeus and his nurse, the goat Amaltheia, on the island of Krete. Later Tantalus was said to have stolen the automaton when it guarded Zeus' temple, or to have persuaded Pandareos to steal it for him. Later texts attempt to replace the automaton with the idea that the golden dog was actually Rhea, transformed in that way by Hephaestus.
