Hephaestus (Greek: Ἥ) φαιστος、 Hephaestus is the god of fire, the god of forging and masonry, and the god of sculpture in ancient Greek mythology. One of the twelve main gods of Olympus. The son of Zeus and Hera (or the only child of Hera), and the husband of Aphrodite or Agria.
Hephaestus is adept at building temples, making various weapons and metal articles, and is highly skilled. He is known as the ancestor of craftsmen and the patron saint of forging. In the islands of Limnos and Sicily, he was initially revered as the god of earth fire. It is said that when the earth roars and vibrates and volcanoes erupt, it is he who is forging iron.
Hephaestus corresponds to Vulcan in Roman mythology. Vulcan himself was an ancient Roman god, but at first he had no more deeds, just a simple incarnation of fire. Later, the Romans confused him with Hephaestus, making him gain the identity of a forging god. It is said that the name of this god originated from the island of Crete, and the word "volcano" in Western languages derives from its name.

According to the Homer Epic, Hephaestus was the son of Zeus and Hera (another saying is that Hera alone gave birth to him by his own willpower). However, due to his ugly appearance, Hera threw him to the foot of Mount Olympus. Hephaestus tossed about in the air for a day and landed on the island of Limnos. From then on, he fell lame. Fortunately, he was picked up and adopted by the sea goddess Thetis.
When he grew up, he learned various crafts, and then made an extremely beautiful chair - the throne of Hephaestus. He quietly placed it in the place where his mother Hera, who did not recognize the mother-child relationship, must pass. The vain Hera immediately took the bait. She liked the charming chair and sat down. Then, her joints were locked by the mechanism of the chair, unable to move, and her magic power disappeared. The gods asked Hephaestus to return to Mount Olympus and release Hera, but Hephaestus repeatedly refused.
Dionysus, the god of wine, intoxicated Hephaestus, placed him on the back of a mule, and took him up Mount Olympus. Hephaestus proposed three requirements: first, Hera admitted that he had abandoned his mistake; The second is to acknowledge his identity as the Lord God of Olympus; The third is to marry Aphrodite, the goddess of love, to him. Hera agreed to the three demands of Hephaestus in order to save herself (another way of saying is that the marriage between Hephaestus and Aphrodite was facilitated by Zeus, because Hephaestus was the most exclusive of all gods, and the marriage of Aphrodite to him could avoid any disagreement among the gods caused by Aphrodite). So after marrying Aphrodite, Hephaestus finally released Hera.
After becoming the god of Olympus, Hephaestus built a magnificent palace for the gods. A workshop was also built on the mountain for forging and smelting tools. "He made a shield for Zeus, a staff for Dionysus, a sun carriage for Helios, a gold arrow and silver arrow for Eros, an impenetrable armor for Achilles, the son of the sea goddess Thetis, and made Pandora out of clay, a metal giant Taros, and a chain for Prometheus, forged by Hephaestus, although he was very sad about this.".
Aphrodite certainly did not like the ugly and lame craftsman god, but there was no way she could do it. The marriage promised by Zeus, the god king, and Hera, the queen of heaven, could only be obeyed. In fact, Aphrodite had always liked Ares, the god of war, Hephaestus' younger brother, and often had secret trysts while Hephaestus was not at home. Hephaestus made a delicate gold net to cover them and make them look ridiculous before the gods. From that day on, Aphrodite hid in her temple and refused to go out, neither seeing Hephaestus, because she was ashamed of her own actions and feared that she would be retaliated by Hephaestus.

Hephaestus used to have daily fun making jewelry, cosmetics, and food for Aphrodite to make her happy. Now Aphrodite's refusal to see him troubled him. He went to ask Hera for an idea for him, and Hera said, "As long as we can make unique ornaments in the world, we can definitely make Aphrodite change his mind." So Hephaestus used the stones of the holy mountain and the sacred fire of Olympus to create an exquisite ring, called "The Loyalty of the Rose.". Hephaestus carved the rose representing beauty and love on the ring, and then engraved it with thorns full of thorns, which implied that love requires a price and responsibility. At the same time, he warned Aphrodite with a sign, "Don't forget the humiliation she once suffered. Be loyal and devoted to Hephaestus."
Hephaestus took the ring and went to see Aphrodite, but the goddess of love remained closed. So he had to place the ring on the steps of the temple. Aphrodite saw the ring, understood the intention of the craftsman god, and made peace with him.
Some legends believe that Agria was Hephaestus' first and only wife. Agria married Hephaestus. He also gave birth to four daughters for Hephaestus, namely, Ocretia (good name), Opheme (praise), Othnia (eloquence), and Philophorus (popular).
The Earth Goddess Gaia once prophesied that Zeus would give birth to a pair of children with Matthias, and the boy among them would become the king of the gods and men. "Zeus was afraid of this, so he swallowed Matthias into his stomach.". Towards the time of childbirth, Zeus had a severe headache and had Hephaestus, the god of fire, chop his head open with an axe. Athena jumped out of his head, and Zeus' headache disappeared.
After that, when Athena came to order a new weapon, Hephaestus began to pursue Athena, because he was lame, so it took a lot of effort to finally catch up with Athena. He wanted to marry her, but was severely reprimanded by Athena. However, in the process, Hephaestus' semen stained the goddess's thigh, and she quickly wiped it with wool. And threw the wool down to earth, and the wool fell to the ground, becoming Alectonius.

Although Hephaestus was lame and irascible, his arms and shoulders were powerful, and his craftsmanship was unmatched. He once made a group of metal men to help him work in a blacksmith's shop; They can even speak up and take over the difficult tasks he has entrusted them with. "He also had a set of tripod tables with gold wheels, which were surrounded by the blacksmith's shop, and he could run to the gods' gatherings on his own, before running back on his own.".
