Bulfinch's Mythology: The Age of Fable
“ CEPHALUS AND PROCRIS Cephalus was a beautiful youth and fond of manly sports. He would rise before the dawn to pursue the chase. Aurora saw him when she first looked forth, fell in love with him, and stole him away. But Cephalus was just married to a charming wife whom he loved devotedly. Her name was Procris. She was a favorite of Diana, the goddess of hunting, who had given her a dog which could outrun every rival, and a javelin which would never fail of its mark ”
