Hestia (the Roman Vesta) is the goddess of the hearth. She was the eldest daughter of Cronus and Rhea, and the sister of Zeus and Hera. Zeus gave her permission not to marry. She gave her throne on Olympus to Hermes, but remained there by the hearth. All other gods traveled and had many adventures, Hestia always remained home and kept fire in the Olympian hearth to welcome all her relatives back. She is a symbol of a warm friendly home.
