Hestia: Greek Goddess of the Hearth and Home
Vesta: Roman Goddess of the Hearth and Home 

Hestia, in the high dwellings of all, both deathless gods and men who walk on earth, you have gained an everlasting abode and highest honor: glorious is your portion and your right. For without you mortals hold no banquet, where one does not duly pour sweet wine in offering to Hestia both first and last.   ~Homeric Hymn to Hestia~

Daughter of Chronos and Rhea, Hestia is Hearth, the first born of the Olympians. Hestia, who discovered how to build houses, extends her power over altars, hearths, and states.

The guardian of innermost thoughts and desires, prayers and sacrifices end with acknowledging Her . Some say the snake here is symbolic of a woman who was complete without a husband or man, while others say the snake is about renewal and regeneration. The snake eats peacefully from Hestia's bowl in this depiction.

A virgin goddess, Hestia can never be ensnared by the goddess of love. Instead of marriage, Zeus granted that her place should be in the very midst of the house. For that reason mortals did not hold banquet without offering to Hestia both first and last, and many homes naturally included an altar to Hestia.

Her Roman name was Vesta, and her Vestal Virgins tended the sacred flame of Rome.
