Hebe
Hebe, the youngest child of Zeus and Hera, was revered as the celestial embodiment of youth and beauty that never aged. She is known as the goddess of youth in Greek mythology because she is the mistress of perpetual beauty and grace. In the Greek language, her name itself meant "youth," and many people thought she could even make the aged seem young again. While many have looked for the Fountain of Youth for many years, the Greeks would have thought that receiving a benediction from Hebe may grant youth. She was believed to possess the ability to resurrect youth in general.
She was responsible for serving the nectar that gave the Olympian gods immortality on Mount Olympus. Hebe was revered as a goddess who could provide youth, although she was more involved in Olympus' everyday tasks, such as serving as Hera's handmaiden and even preparing the king's chariot. She later wed the well-known demigod Hercules, with whom she had two children, Alexiares and Anicetus.
