Romulus

When the city was built, in the first place, Romulus divided all the multitude that were of age to bear arms into military companies, each company consisting of three thousand footmen and three hundred horsemen. Such a company was called a legion, because the warlike were selected out of all. In the second place, he treated the remainder as a people, and this multitude was called populus; a hundred of them, who were the most eminent, he appointed to be councillors, calling the individuals themselves patricians, and their body a senate.
Now the word senate means literally a Council of Elders, and the councillors were called patricians, as some say, because they were fathers of lawful children[*](Cf. Livy, i. 8, 7.); or rather, according to others, because they could tell who their own fathers were, which not many could do of those who first streamed into the city; according to others still, from patronage, which was their word for the protection of inferiors, and is so to this day; and they suppose that a certain Patron, one of those who came to Italy with Evander, was a protector and defender of the poor and needy, and left his own name in the word which designates such activity.
But the most reasonable opinion for any one to hold is that Romulus thought it the duty of the foremost and most influential citizens to watch over the more lowly with fatherly care and concern, while he taught the multitude not to fear their superiors nor be vexed at their honours, but to exercise goodwill towards them, considering them and addressing them as fathers, whence their name of Patricii.
