PERSEUS AND ANDROMEDE

Perseus and his mother Danae, who managed to escape from the cruelty of his grandfather Acrisios with the help of Zeus, took refuge with Polydektes, King of Seriphos. While the young and legendary Perseus quickly became like the King's own son, his mother Danae blew Polydectes' mind and the King wanted to marry him.
However, Polydectes thought that Perseus would make a mishap due to the impetuosity of his youth and wanted to eliminate his son Perseus. 
A long time has passed. The king spread the news around that he would marry Hippodameia, one of the most well-known and beautiful girls of his country. And according to custom, everyone had to give gifts to the King during the festivities. Perseus asked what the King wanted as a gift. The king said he liked horses. Perseus said that he wanted to offer a more honorable gift and that he could bring Medusa's head to him. When the king left this offer unanswered at first, Perseus brought a horse as a gift like everyone else. However, the King did not accept this gift.
"Since you promised me, you must bring Medusa's head," he said.
His aim was to throw off Perseus by giving him this impossible task and to make his young mother Danae, whom he was in love with, his mistress. Medusa was truly an invincible and very scary creature. His huge and disgusting face had a flat nose and two wide ears, long teeth resembling wild boars in his mouth, and on his tanned forehead, instead of hair, coiled snakes spewing venom. The voice of this helpless woman, equipped with bronze arms, resembled wild animals, and those who looked into her terrifying eyes were immediately turned to stone.
When Perseus realized that he had to keep this great promise, he fell into thought. Hermes came to him and said that he could achieve this task with the help of Athena, the goddess of Intelligence. With the genius ideas he received from Athena, he managed to buy from the old Grai a pair of winged sandals, a saddlebag, and a makeshift hair that makes the wearer invisible.
Perseus, who tied the winged sandals to his two feet, put on the artificial hair that made him invisible, and took the saddlebag on his back, set out towards the place where Medusa was. He found the three hideous sisters, the Gorgons, asleep. The mortal approached Medusa. He turned around and swung his sword at Medusa's head so that she would not look at him and petrify him. He put his severed head in his saddlebag. From the blood of Medusa spilled on the ground, the winged horse Pegasus was born.
Perseus flew away. The poisonous snakes seen all over the world today were born from Medusa's blood dripping from the saddlebag on the road.
When Perseus approached the eastern country in the evening, he encountered a new adventure.
A King named Kepheus was ruling in the country he reached. Cassiepeia, the wife of Cepheus, was carried away by her pride and thought that she was more beautiful than the Nereids. God Posseidon, enraged by the disdain of his daughters, sent an irresistible sea monster to haunt Kepheus's homeland.
King Kepheus, who consulted the gods, learned that the only way to escape this disaster was to sacrifice his beautiful daughter Andromede to this sea monster.
When Perseus came to Abyssinia, he found Andromede tied to a huge rock. After learning the truth about the incident, he fell in love with this beautiful girl. Just then the terrible sea monster appeared. As he opened his huge mouth to swallow Andromede, who was tied to the rocks, Perseus jumped out like an arrow and plunged his iron-tipped spear into the monster's chest. Perseus released Andromede's bonds. She took her to her father, King Kepheus, and said that she wanted to get married. The King, who got out of trouble, accepted this offer. The couple, who got married in a magnificent wedding, then took Medusa's severed head and set out for the island of Seriphos.
However, King Polydectes of Seriphos took advantage of Perseus' absence and wanted to possess his mother Danae, and Danae, who resisted, had to take shelter in a temple.
At this very moment and unaware of what was happening, Perseus appeared before King Polydectes and said that he had brought Medusa's head. But King Polydectes, whose heart was full of hatred, told Perseus that he was lying and doubted his victory.
Angered by this attitude of the King, Perseus took Medusa's head out of the bag and handed it to the King. As soon as Polydectes saw Medusa's severed head, he was turned to stone on his throne.
