Hestia is one of the three goddesses of the first Olympian generation, along with Demeter and Hera. She was described as the oldest and youngest of the three daughters of Rhea and Cronus, sisters to three brothers Zeus, Poseidon, and Hades, in that she was the first to be eaten by Kronos. Originally listed as one of the Twelve Olympians, Hestia gave up her seat in favor of newcomer Dionysus to tend to the fire on Mount Olympus. However, there is no ancient source for this claim. Every family hearth was her altar. Of the Olympian gods, Hestia has the fewest exploits, Hestia is unable to take part even in the procession of the gods, let alone the other antics of the Olympians. This nature is illustrated by her giving up her seat in the Olympian twelve to prevent conflict. She is considered to be the first-born of Rhea and Cronus; this is evidenced by the fact that in Greek culture ritual offerings to all gods began with a small offering to Hestia; the phrase "Hestia comes first" from ancient Greek culture denotes this. Immediately after their birth, Kronos swallowed Hestia and her siblings except for the last and youngest, Zeus, who later rescued them and led them in a war against Kronos and the other Titans. Hestia, the oldest daughter "became their youngest child, since she was the first to be eaten by their father and the last to be thrown up again". Poseidon, and Apollo of the younger generation, each aspired to court Hestia, but the goddess was unmoved by Aphrodite's works and swore on the head of Zeus to retain her virginity. A measure of the goddess's ancient primacy—"queenly maid...among all mortal men she is rule of the goddesses", in the words of the Homeric hymn—is that she was owed the first as well as the last sacrifice at every ceremonial assembly of Hellenes, a pious duty related by the mythographers as the gift of Zeus: another mythic inversion if, as is likely, the ritual was too deep-seated and essential for the Olympian reordering to overturn. There are theories that Hestia, as goddess of "home and hearth", was one of the most ancient of the gods later worshiped as Olympians; as a maternal goddess of humans finding safety and homes in caves around a fire, worship of Hestia, by other names, may literally be hundreds of thousands of years old and has continued through classical Greek times to the present day." Hestia evolved into a minor goddess in the same ranks of Pan and Dionysus, who was incorporated into the Olympian order in Hestia's place. At Athens notes "there was a discrepancy in the list of the twelve chief gods, as to whether Hestia or Dionysus was included with the other eleven. The altar to them at the agora, for example, included Hestia, but the east frieze of the Parthenon had Dionysus instead. Her Roman name is Vesta.
