Hestia, the Greek goddess of the hearth and domestic life, embodies the sacred function of fire as a source of warmth, nourishment, and communal unity. Ancient authors such as Homer portray her as the essential guardian of households, emphasizing rituals like offerings and sacrifices to maintain harmony. Plato connects her with the cosmos, presenting her as the "first principle" of existence, while E.
M. Berens highlights her role as the defender of domestic holiness. Later interpretations, including those in the Encyclopaedia Britannica, associate her with universal symbolism, blending her with earth and cosmic order. These diverse viewpoints trace Hestia’s lasting influence from the hearth to the heavens, underscoring her central position in both human and divine spheres.
