We do not see that all Greece, or even a Greek city, formally asked for this right of citizenship, so much desired; but men worked individually to ac… - Numa Denis Fustel de Coulanges

The symbols of this religion became modified in the course of ages. When the people of Greece and Italy began to represent their gods as persons, and to give each one a proper name and a human form, the old worship of the hearth-fire submitted to the common law which human intelligence, in that period, imposed upon every religion. The altar of the sacred fire was personified. They called it Vesta; the name was the same in Latin and in Greek, and was the same that in the common and primitive language designated an altar. By a process frequent enough, a common noun had become a proper name. By degrees a legend was formed. They pictured this divinity to themselves as wearing a female form, because the word used for altar was of the feminine gender. They even went so far as to represent this goddess in statues. Still they could never efface the primitive belief, according to which this divinity was simply the fire upon the altar and Ovid himself was forced to admit that Vesta was nothing else than a "living flame." If we compare this worship of the sacred fire with the worship of the dead, of which wo have already spoken, we shall perceive a close relation between them. ...It is a chaste fire; the union of the sexes must be removed far from its presence. They pray to it not only for riches and health, but also for purity of heart, temperance, and wisdom. "Render us rich and flourishing," says an Orphic hymn; " make us also wise and chaste." ...Still later, when they made the great Vesta of this myth of the sacred fire, Vesta was the virgin goddess. She represented in the world neither fecundity nor power; she was order, but not rigorous, abstract, mathematical order, the imperious and unchangeable law, which was early perceived in physical nature. She was moral order. They imagined her as a sort of universal soul, which regulated the different movements of worlds, as the human soul keeps order in the human system. Thus are we permitted to look into the way of thinking of primitive generations. The principle of this worship is outside of physical nature, and is found in this little mysterious world, this microcosm — man.

The causes of ... [the city's] destruction may be reduced to two. One was the change that took place in the course of time in ideas, resulting from the natural development of the human mind, and which, in effacing ancient beliefs, at the same time caused the social edifice to crumble, which these beliefs had built, and could alone sustain. The other was a class of men who found themselves placed outside this city organization, and who suffered from it. These men had an interest in destroying it, and made war upon it continually. When, therefore, the beliefs, on which this social regime was founded, became weakened, and the interests of the majority of men were at war with it, the system fell. No city escaped this law of transformation; Sparta no more than Athens, Rome no more than Greece. We have seen that the men of Greece and those of Italy had originally the same beliefs, and that the same series of institutions was developed among both; and we shall now see that all these cities passed through similar revolutions.

It is a strong proof of the antiquity of this belief, and of these practices, to find them at the same time among men on the shores of the Mediterranean and among those of the peninsula of India. Assuredly the Greeks did not borrow this religion from the Hindus, nor the Hindus from the Greeks. But the Greeks, the Italians, and the Hindus belonged to the same race; their ancestors, in a very distant past, lived together in Central Asia. There this creed originated and these rites were established. The religion of the sacred fire dates, therefore, from the distant and dim epoch when there were yet no Greeks, no Italians, no Hindus; when there were only Aryas. When the tribes separated they carried this worship with them, some to the banks of the Ganges, others to the shores of the Mediterranean. Later, when these tribes had no intercourse with each other, some adored Brahma, others Zeus, and still others Janus; each group chose its own gods; but all preserved, as an ancient legacy, the first religion which they had known and practiced in the common cradle of their race.
