Romulus

Now it is agreed that the city was founded on the twenty-first of April, and this day the Romans celebrate with a festival, calling it the birthday of their country. And at first, as it is said, they sacrificed no living creature at that festival, but thought they ought to keep it pure and without stain of blood, since it commemorated the birth of their country. However, even before the founding of the city, they had a pastoral festival on that day, and called it Parilia.

At the present time, indeed, there is no agreement between the Roman and Greek months, but they say that the day on which Romulus founded his city was precisely the thirtieth of the month, and that on that day there was a conjunction of the sun and moon, with an eclipse, which they think was the one seen by Antimachus, the epic poet of Teos, in the third year of the sixth Olympiad.[*](754 B.C.)

And in the times of Varro the philosopher, a Roman who was most deeply versed in history, there lived Tarutius, a companion of his, who, besides being a philosopher and a mathematician, had applied himself to the art of casting nativities, in order to indulge a speculative turn of mind, and was thought to excel in it.
