At the same time, as Marcus Helvius was going home from Farther Spain, with an escort of six thousand men, given him by the praetor, Appius Claudius, the Celtiberians, with a very numerous force, met him near the city of Illiturgi. [2] Valerius says, that they had twenty thousand effective men; that twelve thousand of them were killed, the town of Illiturgi taken, and all the adult males put to the sword. [3] Helvius, soon after, arrived at the camp of Cato; and as the region was now free from enemies, he sent back the escort to Farther Spain, and proceeded to Rome, where, on account of his successful services, he entered the city with an ovation. [4] He carried into the treasury, of silver bullion, fourteen thousand pounds' weight; of coined, seventeen thousand and twenty-three denarii;¹ and Oscan² denarii, one hundred and twenty thousand four hundred and thirty-eight.³ [5] The reason for which the senate refused him a triumph was, because he fought under the auspices, and in the province, of another. He had returned, moreover, two years after the expiration of his office, because after he had resigned the government of the province to Quintus Minucius, he was detained there, during the succeeding year, by a severe and tedious sickness; [6] he therefore entered the city in ovation, only two months before his successor, Quintus Minucius, enjoyed a triumph. [7] The latter also brought into the treasury thirty-four thousand [p. 1503]eight hundred pounds' weight of silver, seventy-eight thousand denarii,⁴ and of Oscan denarii two hundred and seventy-eight thousand.⁵
