Selene, madly in love, watched Endymion at any moment that she could. However, one night, she thought of something quite depressing. She realized that since Endymion was a human, he would someday grow old and die. In an attempt to prevent this from happening, Selene approached Zeus (Endymion's father) and asked him to give his son immortality in the form of eternal youth. Zeus granted her wish, but not quite in the way that Selene expected. He placed Endymion into a perpetual slumber, which also prevented him from ever aging.
