They had before their eyes all that paraphernalia of the secret rite —the armed priests, the slaughtered remains of men and beasts scattered about indiscriminately, the altars sprinkled with the blood of the victims and of their murdered countrymen, the awful imprecations, the frightful curses which they had invoked on their family and race —these were the chains which bound them so that they could not flee.
They dreaded their own countrymen more than the enemy. The Romans pressed on from both wings and from the centre and cut down men who were paralysed by fear of gods and men. Only a feeble resistance could be offered by those who were only kept from flight by fear.
The carnage had almost extended to the second line where the standards were stationed when there appeared in the side distance a cloud of dust as though raised by the tread of an immense army. It was Sp. Nautius —some say Octavius Maecius —the commander of the auxiliary cohorts.
They raised a dust out of all proportion to their numbers, for the camp-followers mounted upon the mules were dragging leafy boughs along the ground. At first the arms and standards gradually became visible through the beclouded light, and then a loftier and thicker Cloud of dust gave the appearance of cavalry closing the column.
