Hestia & Demeter

Hestia/Vesta

She was Zeus's sister, and like Athena and Artemis a virgin goddess. She has no distinct personality and she plays no part in the myths. She was the Goddess of the Hearth, the symbol of the home, around which the newborn child must be carried before it could be received into the family. Every meal began and ended with an offering to her.
