Titonus

One time Eos (dawn) slept with Ares, the lover of Aphrodite. Aphrodite took her revenge by giving Eos an insatiable appetite for young men. Eos took the Trojan prince Tithonus, among many others, as a lover, and eventually asked Zeus to grant him immortality, but she forgot to ask for eternal youth along with the immortality, so Tithonus was fated to live forever and grow increasingly older. In time he withered into a parody of a man, and his voice grew shrill. Eos shut this loathsome creature away in a closet, where it turned into a cricket.
