Romans did not like the smell of blood, though they enjoyed the sight of it, and all the solid stonework was pierced with tubes, through which was conducted the stream of spices and saffron, boiled in wine, that the perfume might overpower the scent of slaughter below. Wild beasts tearing each other to pieces might, one would think, satisfy any taste of horror; but the spectators needed even nobler game to be set before their favorite monsters--men were brought forward to confront them. Some of these were at first in full armor, and fought hard, generally with success; and there was a revolving machine, something like a squirrel's cage, in which the bear was always climbing after his enemy, and then rolling over by his own weight. Or hunters came, almost unarmed, and gaining the victory by swiftness and dexterity, throwing a piece of cloth over a lion's head, or disconcerting him by putting their fist down his throat. But it was not only skill, but death, that the Romans loved to see; and condemned criminals and deserters were reserved to feast the lions, and to entertain the populace with their various kinds of death. Among these condemned was many a Christian martyr, who witnessed a good confession before the savage-eyed multitude around the arena, and 'met the lion's gory mane' with a calm resolution and hopeful joy that the lookers-on could not understand. To see a Christian die, with upward gaze and hymns of joy on his tongue, was the most strange unaccountable sight the Coliseum could offer, and it was therefore the choicest, and reserved for the last part of the spectacles in which the brute creation had a part. The carcasses were dragged off with hooks, and bloodstained sand was covered with a fresh clean layer, the perfume wafted in stronger clouds, and a procession came forward--tall, well-made men, in the prime of their strength. Some carried a sword and a lasso, others a trident and a net; some were in light armor, others in the full heavy equipment of a soldier; some on horseback, some in chariots, some on foot. They marched in, and made their obeisance to the Emperor; and with one voice, their greeting sounded through the building, Ave, Caesar, morituri te salutant! 'Hail, Caesar, those about to die salute thee!' They were the gladiators--the swordsmen trained to fight to the death to amuse the populace. They were usually slaves placed in schools of arms under the care of a master; but sometimes persons would voluntarily hire themselves out to fight by way of a profession: and both these, and such slave gladiators as did not die in the arena, would sometimes retire, and spend an old age of quiet; but there was little hope of this, for the Romans were not apt to have mercy on the fallen. Fights of all sorts took place--the light-armed soldier and the netsman --the lasso and the javelin--the two heavy-armed warriors--all combinations of single combat, and sometimes a general melee. When a gladiator wounded his adversary, he shouted to the spectators, Hoc habet! 'He has it!' and looked up to know whether he should kill or spare. If the people held up their thumbs, the conquered was left to recover, if he could; if they turned them down, he was to die: and if he
