An oracle had announced Acrisius, king of Argos, that he would die at the hands of his own grandson. To avoid this, Acrisius had his daughter Danae locked up in a bronze tower to prevent him from dealing with any male. However, the king of the gods, Zeus, was transformed into a rain of gold that fell on Danae from the roof and left her pregnant. Thus, the princess conceived Perseus. Upon hearing, Acrisus, not believing the birth of the child as divine, threw him with Danae into the sea in a wooden chest. The sea was calmed by Poseidon at the request of Zeus, and the mother and son survived and reached the coast of the island of Serifos. King Polidectes ruled that island, and his brother Dictis picked up the woman and the child, whom he would raise as his son.
Later, Polidectes fell in love with Danae. Thinking that the young Perseus could be a hindrance to his plans, he tried to get rid of him by a stratagem: he made everyone believe that he wanted to conquer Princess Hippodamia and asked each of the inhabitants of the island to give him a gift as present, to be able to offer it in turn to the princess. Perseus said he would not hesitate to hand over anything: even if it was to be the head of Medusa, which was one of the three Gorgons and could turn men to stone just by looking. Polidectes accepted as gifts the horses of other inhabitants of the island, but he did not accept those of Perseus, and ordered him to bring him the head of the Gorgon that he had promised him.
Perseus left, guided by the gods Athena and Hermes, in search of the daughters of Forcis: the grayas, sisters of the gorgons. The grayas were three old women who only had one eye and one tooth for all three, and they passed them to each other. Perseus snatched the eye, and, in exchange for returning it, forced them to confess where the nymphs lived, their sisters.
Thus, Perseus found the nymphs, from which he would obtain a magic bag to contain his head without danger, winged sandals and the helmet of Hades, which made invisible to whoever was wearing it. In addition, he received from Hermes a steel sickle with which he could cut the head of Medusa, and received from Athena a shield that shined like a mirror.
Armed with these objects, Perseus was introduced to the abode of the Gorgons. While the Gorgons were asleep, Perseus approached them. Athena guided the hand of Perseus, who also used as a mirror the bronze shield that the goddess had lent him to see Medusa without looking directly at her. Thus, Perseus managed to cut off the head of the Gorgon, from which the winged horse Pegasus and the giant Crisaor were born. Esteno and Euriale, the immortal sisters of Medusa, sought out Perseus but could not find him because Hades’s helmet made him invisible.
Perseus went to the country where Atlas reigned, to whom, once there, he asked for hospitality. Atlas, however, recalled that an oracle had told him that a son of Zeus would come to steal the fruits of the garden of the Hesperides, and tried to expel Perseus. This one used the head of Medusa, and Atlas was turned into stone.
Arriving in Ethiopia, Perseus found Andromeda chained to a rock: she was left there by her parents, the kings Cepheus and Cassiopeia, to be devoured by a sea monster, Ceto, who had been sent by the gods as punishment for having Cassiopeia boasted of being more beautiful than the Nereids. An oracle of Amun had said that they would only be free of the monster if Andromeda were offered as food. Perseus fell in love with Andromeda and decided to free her. After asking the hand of the princess to Cepheus and Cassiopeia, he killed the monster with his sword.
Afterwards, Perseus returned to Serifos. There, Dictis and Danae had taken refuge in a temple fleeing the harassment of Polidectes. Perseus appeared before Polidectes and before all his court, took out the head of Medusa and showed it to all the audience, which was petrified. Then he made Dictis king of Serifos, returned to Hermes the winged sandals and gave him the pouch and helmet of Hades, and handed the head of Medusa to Athena, who would put it on his shield.
Finally, Perseus decided to return to Argos, with Danae and Andromeda. Acrisius, having learned that his grandson was traveling to meet him, traveled to Larisa to watch some games. Perseus also went to those games and participated in the discus throwing, but he did so with such bad luck that he hit Acrisius in the head and killed him, thus fulfilling the prophecy. Due to this accidental death, Perseus did not want to continue governing in Argos, his legitimate kingdom. His second uncle Megapentes, Danae’s cousin, was king of Tiryns, so they exchanged the kingdom: Perseus became King of Tiryns and Megapentes of Argos.
