The twenty-first of April was a festal day among the shepherds, and it was chosen as the one on which the new city should be begun (753 B.C.). In the morning of the day, it was customary, so they say, for the country people to purify themselves by fire and smoke, by sprinkling themselves with spring water, by formal washing of their hands, and by drinking milk mixed with grape-juice. During the day they offered sacrifices, consisting of cakes, milk, and other eatables, to Pales, the god of the shepherds. Three times, with faces turned to the east, a long prayer was repeated to Pales, asking blessings upon the flocks and herds, and pardon for any offences committed against the nymphs of the streams, the dryads of the woods, and the other deities of the Italian Olympus. This over, bonfires of hay and straw were lighted, music was made with cymbal and flute, and shepherds and sheep were purified by passing through the flames. A feast followed, the simple folk lying on benches of turf, and indulging in generous draughts of their homely wines, such, probably, as the visitor to-day may regale himself with in the same region. Towards evening, the flocks were fed, the stables were cleansed and sprinkled with water with laurel brooms, and laurel boughs were hung about them as adornments. Sulphur, incense, rosemary, and fir-wood were burned, and the smoke made to pass through the stalls to purify them, and even the flocks themselves were submitted to the same cleansing fumes. The beginning of a city in the olden time was a serious matter, and Romulus felt the solemnity of the acts in which he was about to engage. He sent men to Etruria, from which land the religious customs of the Romans largely came, to obtain for him the minute details of the rites suitable for the occasion. At the proper moment he began the Etrurian ceremonies, by digging a circular pit down to the hard clay, into which were cast with great solemnity some of the first-fruits of the season, and also handfuls of earth, each man throwing in a little from the country from which he had come. The pit was then filled up, and over it an altar was erected, upon the hearth of which a fire was kindled. Thus the centre of the new city was settled and consecrated. Romulus then harnessed a white cow and a snow-white bull to a plow with a brazen share, and holding the handle himself, traced the line of the future walls with a furrow (called the pomoerium [Footnote: _Pomoerium_ is composed of _post_, behind, and _murus_, a wall. The word is often used as meaning simply a boundary or limit of jurisdiction. The _pomoerium_ of Rome was several times enlarged.]), carrying the plow over the places where gates were to be left, and causing those who followed to see that every furrow as it fell was turned inwards toward the city. As he plowed, Romulus uttered the following prayer:
