In fact the combat was interesting. The secutor, of course, could have disposed of his antagonist in a trice, if he had only been able to reach him. But a clumsy, heavy secutor never could reach a nimble, agile retiarius. The one Brinnaria was watching was more than usually light-footed and skipped about his adversary in a taunting, teasing way. Again and again he cast his net intentionally too short, merely to show how easily he could recover it and escape his opponent’s onset. He danced, capered, pretended to be lame and that he could not avoid being overtaken, led his pursuer on, out-manoeuvred him, derided him; twice he lunged through the flapping straps of his kilt and grazed his thigh. The secutor was barely scratched, but his blood trickled down his shin-guard and he was limping.

Then, all in a flash, the retiarius pirouetted too rashly, slipped on ton the sand, fell sprawling, failed to rise in time, and was slashed deeply all down one calf. He rolled over in a last effort to escape, but the secutor kicked him in the ribs and, before he could recover, sent the trident spinning with a second kick and set his foot upon his victim’s neck. So standing he rolled his eyes over that part of the audience nearest him to discover whether it was the pleasure of the lookers-on that the defeated man should be killed or spared.

Now it so happened that nearly all the spectators in that part of the audience were watching a far more exciting contest farther out in the arena, where two Indian elephants, each manned by a crew of five picked men, were clashing in a terrific struggle No one, except Brinnaria, had any eyes for the plight of the young retiarius below them The secutor beheld indifferent faces gazing over his head The few thumbs he could see pointed outward. Brinnaria, to be sure, was holding out her right arm, thumb flat, and doing her best to attract the secutor’s attention. She failed. He glanced, indeed, at the Vestals, but as three of them sat impassive he missed Brinnaria’s imperious gesture. He prepared to put his foe to death. First, however, he looked further along the front rows to make sure that he had the permission of the general audience, since the occupants of the Imperial box and of the Vestals loge seemed to ignore him.

Brinnaria perceived that he would probably not look again in her direction; that as soon as his roving eyes came back from their unhurried survey of the audience, he would deliver the fatal blow. She quickly knotted the corner of her robe to the arm of her chair, squirmed out of it, and threw it over the parapet. The robe of a Roman lady was sleeveless and seamless, rather like a very long pair of very thin blankets, all in one piece. Tied, as she had tied it, by one corner, it made a sort of rope as it hung. She had acted so quickly that no one noticed her, not even Manlia, who sat next her, staring fascinatedly at the spectacle of the wrestling elephants and their warring crews.

Grasping her robe firmly with both hands, escaping by a hair’s-breadth the despairing clutch of the horrified Manlia, Brinnaria half vaulted, half rolled over the parapet, swung sailor-fashion to the rope her robe formed, went down it, hand over hand, raced across the sand and faced the victorious secutor.

He, although a foreigner and a savage, had been long enough in Rome to know perfectly what a Vestal was and he recoiled from her in a panic no less than he would have felt had the goddess Vesta herself come down from the sky to balk him of his prey.

The next instant no one was regarding the death-struggle of the elephants, nor any other of the scores of fights ended, ending, under way or just begun. Every human being in the audience was staring at the amazing spectacle of a Vestal virgin, clad only in her thin, clinging tunic, standing over a fallen retiarius and facing an appalled and dumbfounded secutor.

The place fell very still. So still that the shrill voice of a street-gamin, a boy from the Via Sacra, was audible throughout the vast enclosure from gallery to gallery. He yelled in his cutting falsetto: “Good for you, Sis!”

But his neighbors silenced him at once and not even any other ragamuffin lifted his voice. The audience were startled mute. They were quite ready to applaud the girl’s daring, but the shocking impropriety of her breach of decorum struck them dumb.

The Emperor, roused from his meditations by the sudden hush, looked about him for the cause of it and saw the situation. He leaned forward, arm out, thumb flat against the extended fingers. The secutor sheathed his sword.
