The messengers of Agnias were hastening away from Kittim, bearing to their master the promise of the inhabitants that Yaniah should become his wife, when Turnus, king of Benevento, arrived on the same errand. His suit was rejected, for the people of Kittim were afraid-to break the promise given to Agnias. In his anger, Turnus went to Sardinia to make war upon King Lucus, a brother of Agnias, intending to deal with the latter as soon as the other was rendered harmless.
Hearing of the design hatched by Turnus, Agnias hastened to Sardinia to the assistance of his brother, and a battle took place in the Valley of Campania. Against Turnus were arrayed Agnias, his brother Lucus, and the son of the latter, Niblos, whom his father had appointed commander-in-chief of the Sardinian troops. In the first encounter, Turnus was the victor, and the Sardinians lost their general Niblos.
But in the second engagement the army of Turnus was routed completely, and he himself was left dead on the field. His army fled, pursued closely by Agnias as far as the cross-road between Rome and Albano. Niblos' body was put inside of a golden statue, and his father erected a high tower over his grave, and another over the grave of Turnus, and these two buildings, connected by a marble pavement, stand opposite to each other, on the cross-road at which Agnias left off from following after the fugitive army.
