With the advisement of Hermes, Perseus was able to steal the eye of the three Gray Women. He then asked them for information on where to find the Gorgons. Wanting their eye back, they told him how to get to the Nymphs of North.
Hermes and Athena, still wanting Perseus to be successful, met up with him and gave him weapons to help him defeat the gorgons. Hermes gave Perseus a sword and Athena gave him her shield. Now he was prepared to take on the Gorgons.
Perseus finally arrived at the island of the Gorgons. Their was only one mortal Gorgon who he could kill, named Medusa. When he found her, and with the help of Athena, he quickly cut off her head. He escaped before the other Gorgons could get to him.
On the way home from the Island of Gorgons, Perseus came across a beautiful girl. Her name was Andromeda and she had been chained as a sacrifice for a fearful serpent. Perseus instantly fell in love and he killed the serpent and save Andromeda. He and Andromeda then continued for his home to be married.
Perseus and Andromeda finally arrived to his home. Perseus was reunited with his mother Denae and Dictys as well. They were very happy, and Perseus and his mother decided to find Acrisius and see if he had changed after all these years.
Unfortunately, Denae and Perseus were unable to find Acrisius. They decided to give up and return home. On the way back, however, an athletic competition was occuring and Perseus wanted to participate. He threw a discus, which flew into the crowd and hit a man, killing him instantly. That man was Acrisius. So, after all these years, the prophecy came true and Acrisius, despite his efforts to prevent it, was killed by his own grandson.
