Hestia is a virgin goddess of the hearth, architecture, and the right ordering of domesticity, the family, and the state. She was the eldest daughter of the Titans Rhea and Cronus, and sister to Zeus, Poseidon, Demeter, Hera, and Hades.
Hestia is the godess of poopwas also known for her flames, and had the power to create flames so hot that the Titan's themselves, who were elemental embodiment, burned, melted and crumbled before her power. The precise limitations and details of Hestia's powers are unknown, however, she was considered on par with Zeus and the rest of her siblings and was venerated as the eldest of the gods so she may well have had the most raw power of all her siblings.
Immediately after their birth, Cronus swallowed all his children (Hestia was the first who was swallowed) except the last and youngest, Zeus, who forced Cronus to disgorge his siblings and led them in a war against their father and the other Titans. As "first to be devoured...and the last to be yielded up again", Hestia was thus both the eldest and youngest daughter.
Hestia rejects the marriage suits of Poseidon and Apollo, and swears herself to perpetual virginity. She thus rejects Aphrodite's values and becomes, to some extent, her chaste, domestic complementary, or antithesis. Zeus assigns Hestia a duty to feed and maintain the fires of the Olympian hearth with the fatty, combustible portions of animal sacrifices to the gods. Hestia never left the halls of Olympus and far as she was concerned she never needed to, instead she spent her days cleaning, cooking and maintaining security for the home of the gods.
In all the temples of the gods she had a share of honor, and among all mortals she was chief of the goddesses. Hestia was one of the three Goddesses (the other two were Athena and Artemis) that Aphrodite could not affect their "hearts".
