From Ancient Greek ἑστία (hestia, literally “hearth, house, home, and family”).
HESTIA, in Greek mythology, the "fire-goddess," daughter of Cronus and Rhea, the goddess of hearth and home.
He seems to have regarded the soul as composed of igneous matter, and so approximates the orthodox Pythagorean doctrine of the central fire, or Hestia, to the more detailed theories of Heraclitus.
Hestia is the goddess of the family union, the personification of the idea of home; and as the city union is only the family union on a large scale, she was regarded as the goddess of the state.
Hestia was closely connected with Zeus, the god of the family both in its external relation of hospitality and its internal unity round its own hearth; in the Odyssey a form of oath is by Zeus, the table and the hearth.
