were at that time ruled by Latinus, the son of Faunus. He came ashore at Laurentum, by the mouth of the river Numicius, where in obedience to some oracle he is said to have made preparations to dwell. The ruler of the land, Latinus, tried to prevent his settling in the land, and joined in battle with him, but was defeated. Then, as the result of dreams that appeared to both leaders, they effected a reconciliation, and Latinus both granted the other a settlement there and gave him his daughter Lavinia in marriage. Thereupon Aeneas founded a city, which he named Lavinium; and the country was called Latium, and the people there were termed Latins.

There his followers ate their tables, which were of parsley or of the harder portions of bread loaves; for they had no real tables. Furthermore, a white sow leaped from his boat and running to the Alban mount, named after her, gave birth to a litter of thirty, which indicated that in the thirtieth year his children should get fuller possession of both land and sovereignty. Since he had heard of these portents beforehand from an oracle he ceased his wanderings, sacrificed the sow, and prepared to found a city. Latinus would not allow him to do this; but after being defeated in war, he gave Aeneas his daughter Lavinia in marriage. Aeneas then founded a city and called it Lavinium.
