Hephaestus corresponds to Vulcan in Roman mythology, and Vulcan itself is the god of ancient Rome. But at first, he didn't have any more deeds, just a simple flame incarnation. Later, the Romans confused him with hephaestus, making him a fake god. It is said that the name of this god originated from Crete, and the word "volcano" in western languages is derived from its name.
Myths and legends
According to the description in Homer's epic, hephaestus was the son of Zeus and Hera (another way of saying that Hera gave birth to him by her own will), but because hephaestus was ugly, Hera threw him at the foot of Olympus, and hephaestus tossed him in the air for a day and landed on Lemnos Island. From then on, he became a cripple. Fortunately, he was picked up and adopted by Tethys, the sea god.
When he grew up, he learned all kinds of crafts, and then built an extremely beautiful chair-the throne of hephaestus. He quietly put it in the place where Hera, the mother who denied the mother-child relationship, had to pass.
The vain Hera immediately took the bait. She likes this charming chair and sits on it. Then, her joints were locked by the mechanism of the chair and her magic disappeared. The gods asked hephaestus to return to Olympus and release Hera, but hephaestus refused again and again.
