Description:

[ca. 500 BCE] King Romus was the first in the western land to discover and conduct four-horse chariot races in honor of the Sun and the Four Elements under him, that is, earth and sea and fire and air. Romus gave names to those four elements. To Earth, the Prasinon faction, that is Green; to Sea, or the waters, the Veneton faction, as Blue; to Fire the Rousion faction, as Red;

§ 7.176 and to Air the Albon faction, as white. And from this he devised the four factions in Rome. He called the Prasinon faction, which in the Roman language is “enduring”, praesenteuein, to take the first seats, because it is said to remain, since the green earth stands for ever with its groves. He called the Veneton from there being a large country under Roman rule called Venetzia, whose metropolis is Aquileia, and from there come the blue, that is Venetzia, dyes for clothes. He joined to the Prasinon faction, Earth, the white, Air he says, since it rains and assists and suits the earth. And to the Veneton faction, the Waters, he joined the Rousion faction, Fire, making it subordinate, since water quenches fire.
So the inhabitants of Rome were divided into factions, and no longer were in concord with each other, because they desired their own victory and devoted themselves to their faction as to some religion. There was a great schism in Rome and the factions felt great enmity for each other in Rome, after Romus thought up the spectacle of horse-racing for them. When, in whatever faction, Romus saw people who favored the demes and senators who were angry and resistant to him on account of his brother’s death or any other cause,
