All the fighting men of Samnium were ordered to appear at the town of Aquilonia. A tabernacle, two hundred feet square, and covered with linen, was erected in the midst of the camp. Within it a venerable man named Ovius Pacctius offered sacrifice after an ancient ritual contained in an old linen book. The imperator or general then ordered the nobles to be called in separately: each as he entered beheld through the gloom of the tabernacle the altar in the centre, about which lay the bodies of the victims, and around which stood centurions with drawn swords. He was required to swear, imprecating curses on himself, his family, and his race, if he did not in the battle go whithersoever the imperator ordered him; if he fled himself, or did not slay any one whom he saw flying. Some of the first summoned, refusing to swear, were slain, and their bodies lying among those of the victims served as a warning to others. The general selected ten of those who had thus sworn, each of whom was directed to choose a man till the number of sixteen thousand was completed, which was named from the tabernacle the Linen legion. Crested helmets and superior arms were given them for distinction. The rest of the army, upwards of twenty thousand men, was little inferior in any respect to the Linen legion. The Roman armies entered Samnium; and while Papirius advanced to Aquilonia, Carvilius sat down before a fortress named Cominium, about twenty miles from that place. The ardour for battle is said to have been shared to such an extent by all the Roman army, that the pullarius, or keeper of the sacred fowl, made a false report of favourable signs. The truth was told to the consul as he was going into battle; but he said the signs reported to him were good, and only ordered the pullarii to be placed in the front rank; and when the guilty one fell by the chance blow of a _pilum_, he cried that the gods were present, the guilty was punished. A crow was heard to give a loud cry as he spoke; the gods, he then declared, had never shown themselves more propitious, and he ordered the trumpets to sound and the war-cry to be raised.
