There were plenty of whispered stories current as to his true identity. Some said he was an impoverished landholder whom Commodus had met by accident when traveling in Northern Italy. But it was much more commonly believed he was the emperor's twin brother, spirited away at birth by midwives, and the stories told to account for that were as remarkably unlikely as the tale itself; as for instance, that a soothsayer had prophesied how Commodus should one day mount the throne and that he and his twin brother would wreck Rome in civil war—a warning hardly likely to have had much weight with the father, Marcus Aurelius, although the mother was more likely to have given credence to it.
Whatever the truth of his origin, Pavonius Nasor never ran the risk of telling it. He kept his sinecure by mastering his tongue, preserving almost bovine speechlessness. When he and Commodus met face to face he never seemed to see the joke of the resemblance, never laughed at Commodus' obscenely vivid jibes at his expense, nor once complained of his anomalous position. He appeared to be a man of no ambition other than to get through life as easily as might be—of no personal dignity, no ruling habits, but possessed of imitative talent that enabled him, without the slightest trouble, to adopt the very gait and gesture of the emperor whom he impersonated.
As he strode ahead along the tunnel he received the guards' salute with merely enough nod of recognition to deceive an onlooker not in the secret. (It was Pavonius Nasor's half-indulgent, rather lazy smile that had persuaded Rome and even the praetorian guards that Commodus was an easy-going, sensual, good humored man.)
There was a box at one end of the private arena, over the gate where the horses entered, so placed as to avoid the sun's direct rays. It was reached by a short stairway from an anteroom that opened on the tunnel. There was no other means of access to the box. It's wooden sidewalls, finished to resemble gilded eagle's wings, projected over the arena so that it was well screened and in shadow. There was none, observing from below, who could have sworn it had not been the emperor himself who sat in the box and watched Paulus the gladiator showing off his skill.
The assembled gladiators, perfectly aware of Paulus' true identity, went through the farce of solemnly saluting as the emperor the man who stared down at them from beneath an awning's shadow between golden eagle's wings, and who returned the salute with a wave of the arm that all Rome could have recognized.
Commodus, nearly as naked as when he was born, came running from a dressing room and pranced and leaped over the sand to bring the sweat- beads to his skin; then, snatching at the nearest gladiator, wrestled with him until the breathless victim cried for mercy; dropped him then, as crushed as if a python had left a job half-finished, and shouted for the ashen sword-sticks. In a minute, with a leather buckler on his left arm, he was parrying the thrusts and blows of six men, driving and so crowding them on one another's toes that only two could seriously answer the terrific flailing of his own ash stick. He named them, named his blow, and laid them one by one, half-stunned and bleeding on the sand, until the last one by a quick feint landed on him, raising a great crimson welt across his shoulders.
"Well done!" Commodus exclaimed and smote him on the skull so fiercely that he broke the sword-stick. "You have killed him," said a senator as two men promptly seized the victim's arms to drag him out.
"Possibly," said Commodus. "That blow I landed on him would have killed a horse. But he is fortunate. He dies proud—prouder than you ever will, Varronius! He got past Paulus' guard! Would you like to attempt it? Woman! How I loathe you soft, effeminate, sleek senators! You fear death and you fear life equally! Where is Narcissus? Where are those men who are to try to kill me at my birthday games?"
There was no answer from Narcissus. Commodus forgot him in a moment, called for javelins and hurled them at a target, then at half-a-dozen targets, hitting all six marks exactly in the middle as he spun himself on one heel.
"I am in fettle!" he exclaimed, clapping the back of the senator whom he had scurrilously insulted a moment ago. If he was conscious of applause from the group of courtiers and gladiators he gave no sign of it. What pleased him was his own ability, not their praises.
