As for the day they began to build the city, it is universally agreed to have been the twenty-first of April, and that day the Romans annually keep holy, calling it their country's birthday. At first, they say, they sacrificed no living creatures on this day, thinking it fit to preserve the feast of their country's birthday pure and without stain of blood. Yet before ever the city was built, there was a feast of herdsmen and shepherds kept on this day, which went by the name of Palilia. The Roman and Greek months have now little or no agreement; they say, however, the day on which Romulus began to build was quite certainly the thirtieth of the month, at which time there was an eclipse of the sun which they conceive to be that seen by Antimachus, the Teian poet, in the third year of the sixth Olympiad. In the times of Varro the philosopher, a man deeply read in Roman history, lived one Tarrutius, his familiar acquaintance, a good philosopher and mathematician, and one, too, that out of curiosity had studied the way of drawing schemes and tables, and was thought to be a proficient in the art; to him Varro propounded to cast Romulus's nativity, even to the first day and hour, making his deductions from the several events of the man's life which he should be informed of, exactly as in working back a geometrical problem; for it belonged, he said, to the same science both to foretell a man's life by knowing the time of his birth, and also to find out his birth by the knowledge of his life. This task Tarrutius undertook, and first looking into the actions and casualties of the man, together with the time of his life and manner of his death, and then comparing all these remarks together, he very confidently and positively pronounced that Romulus was born the twenty-first day of the month Thoth, about sun-rising; and that the first stone of Rome was laid by him the ninth day of the month Pharmuthi, between the second and third hour. For the fortunes of cities as well as of men, they think, have their certain periods of time prefixed, which may be collected and foreknown from the position of the stars at their first foundation. But these and the like relations may perhaps not so much take and delight the reader with their novelty and curiosity as offend him by their extravagance. The city now being built, Romulus enlisted all that were of age to bear arms into military companies, each company consisting of three thousand footmen and three hundred horse. These companies were called legions, because they were the choicest and most select of the people for fighting men. The rest of the multitude he called the people; an hundred of the most eminent he chose for counselors; these he styled patricians, and their assembly the senate, which signifies a council of elders.
