Ascanius seems to have been well disposed to do justice in the case, for he not only sought out Lavinia and induced her to return to the capital with her little son, but he finally concluded to give up Lavinium to her entirely, as her own rightful dominion, while he went away and founded a new city for himself. He accordingly explored the country around for a favorable site, and at length decided upon a spot nearly north of Lavinium, and not many miles distant from it. The place which he marked out for the walls of the city was at the foot of a mountain, on a tract of somewhat elevated ground, which formed one of the lower declivities of it. The mountain, rising abruptly on one side, formed a sure defense on that side: on the other side was a small lake, of clear and pellucid water. In front, and somewhat below, there were extended plains of fertile land. Ascanius, after having determined on this place as the site of his intended city, set his men at work to make the necessary constructions. Some built the walls of the city, and laid out streets and erected houses within. Others were employed in forming the declivity of the mountain above into terraces, for the cultivation of the vine. The slopes which they thus graded had a southern exposure, and the grapes which subsequently grew there were luxurious and delicious in flavor. From the little lake channels were cut leading over the plains below, and by this means a constant supply of water could be conveyed to the fields of grain which were to be sown there, for purposes of irrigation. Thus the place which Ascanius chose furnished all possible facilities both for maintaining, and also for defending the people who were to make it their abode. The town was called Alba Longa, that is long Alba. It was called _long_ to distinguish it from another Alba. It was really long in its form, as the buildings extended for a considerable distance along the border of the lake. Ascanius reigned over thirty years at Alba Longa, while Lavinia reigned at Lavinium, each friendly to the other and governing the country at large, together, in peace and harmony. In process of time both died. Ascanius left a son whose name was Iulus, while Æneas Silvius was Lavinia's heir.
