The blood that ran then must have been in rillets too thin to slake Caracalla's thirst, for simultaneously almost, he was in Gaul, in Dacia—wherever there was prey. African by his father, Syrian on his mother's side, Caracalla was not a panther merely; he was a herd of them. He had the cruelty, the treachery and guile of a wilderness of tiger-cats. No man, said a thinker, is wholly base. Caracalla was. He had not a taste, not a vice, even, which was not washed and rewashed in blood. In a moment of excitement Commodus set his guards on the spectators in the amphitheatre; the damage was slight, for the Colosseum was so constructed that in two minutes the eighty or ninety thousand people which it held could escape. Caracalla had the exits closed. Those who escaped were naked; to bribe the guards they were forced to strip themselves to the skin. In the circus a vestal caught his eye. He tried to violate her, and failing impotently, had her buried alive. "Caracalla knows that I am a virgin, and knows why," the girl cried as the earth swallowed her, but there was no one there to aid.

Such things show the trend of a temperament, though not, perhaps, its force. Presently the latter was displayed. For years those arch-enemies of Rome, the unconquerable Parthians, had been quiet; bound, too, by treaties which held Rome's honor. Not Caracalla's, however; he had none. An embassy went out to Artobane, the king. Caracalla wished a bride, and what fairer one could he have than the child of the Parthian monarch? Then, too, the embassy was charged to explain, the marriage of Rome and Parthia would be the union of the Orient and the Occident, peace by land and sea. Artobane hesitated, and with cause; but Caracalla wooed so ardently that finally the king said yes. The news went abroad. The Parthians, delighted, prepared to receive the emperor. When Caracalla crossed the Tigris, the highroad that led to the capital was strewn with sacrifices, with altars covered with flowers, with welcomings of every kind. Caracalla was visibly pleased. Beyond the gates of the capital, there was the king; he had advanced to greet his son-in-law, and that the greeting might be effective, he had assembled his nobles and his troops. The latter were armed with cymbals, with hautbois, and with flutes; and as Caracalla and his army approached, there was music, dancing and song; there were libations too, and as the day was practically the wedding of East and West, there was not a weapon to be seen—gala robes merely, brilliant and long. Caracalla saluted the king, gave an order to an adjutant, and on the smiling defenceless Parthians the Roman eagles pounced. Those who were not killed were made prisoners of war. The next day Caracalla withdrew, charged with booty, firing cities as he went.

A little before, rumor reached him that a group of the citizens of Alexandria had referred to him as a fratricide. After the adventure in Parthia he bethought him of the city which Alexander had founded, and of the temple of Serapis that was there. He wished to honor both, he declared, and presently he was at the gates. The people were enchanted; the avenues were strewn with flowers, lined with musicians. There were illuminations, festivals, sacrifices, torrents of perfumes, and through it all Caracalla passed, a legion at his heels. To see him, to participate in the succession of prodigalities, the surrounding country flocked there too. In recognition of the courtesy with which he was received, Caracalla gave a banquet to the magnates and the clergy. Before his guests could leave him they were killed. Through the streets the legion was at work. Alexandria was turned into a cemetery. Herodian states that the carnage was so great that the Nile was red to its mouth.

In Rome at that time was a prefect, Macrin by name, who had dreamed the purple would be his. He was a swarthy liar, and his promises were such that the pretorians were willing that the dream should come true. Emissaries were despatched, and Caracalla was stabbed. In his luggage poison was found to the value of five million five hundred thousand drachmae. What fresh turpitude he was devising no one knew, and the discovery might serve as an epitaph, were it not that by his legions he was adored. No one had abandoned to the army such booty as he.

Meanwhile, in a chapel at Emissa, a boy was dancing indolently to the kiss of flutes. A handful of Caracalla's soldiers passed that way, and thought him Bacchus. In his face was the enigmatic beauty of gods and girls—the charm of the dissolute and the wayward heightened by the divine. On his head was a diadem; his frail tunic was of purple and gold, but the sleeves, after the Phoenician fashion, were wide, and he was shod with a thin white leather that reached to the thighs. He was fourteen, and priest of the Sun. The chapel was roomy and rich. There was no statue—a black phallus merely, which had fallen from above, and on which, if you looked closely, you could see the image of Elagabal, the Sun.

The rumor of his beauty brought other soldiers that way, and the lad, feeling that Rome was there, ceased to dance, strolling through pauses of the worship, a troop of galli at his heels, surveying the intruders with querulous, feminine eyes.

Presently a whisper filtered that the lad was Caracalla's son. There were centurions there that remembered Semiamire, the lad's mother, very well; they had often seen her, a superb creature with scorching eyes, before whom fire had been carried as though she were empress. It was she who had put it beyond Caracalla's power to violate that vestal when he tried. She was his cousin; her life had been passed at court; it was Macrin who had exiled her. And with the whisper filtered another—that she was rich; that she had lumps of gold, which she would give gladly to whomso aided in placing her Antonin on the throne. There were gossips who said ill-natured things of this lady; who insinuated that she had so many lovers that she herself could not tell who was the father of her child; but the lumps of gold had a language of their own. The disbanded army espoused the young priest's cause; there was a skirmish, Macrin was killed, and Heliogabalus was emperor of Rome.

"I would never have written the life of this Antonin Impurissimus," said Lampridus, "were it not that he had predecessors." Even in Latin the task was difficult. In English it is impossible. There are subjects that permit of a hint, particularly if it be masked to the teeth, but there are others that no art can drape. "The inexpressible does not exist," Gautier remarked, when he finished a notorious romance, nor does it; but even his pen would have balked had he tried it on Heliogabalus.

In his work on the Caesars, Suetonius drew breath but once—he called Nero a monster. Subsequently he must have regretted having done so, not because Nero was not a monster, but because it was sufficient to display the beast without adding a descriptive placard. In that was Suetonius' advantage; he could describe. Nowadays a writer may not, or at least not Heliogabalus. It is not merely that he was depraved, for all of that lot were; it was that he made depravity a pursuit; and, the purple favoring, carried it not only beyond the limits of the imaginable, but beyond the limits of the real. At the feet of that painted boy, Elephantis and Parrhasius could have sat and learned a lesson. Apart from that phase of his sovereignty, he was a little Sardanapalus, an Asiatic mignon, who found himself great.

It would have been curious to have seen him in that wonderful palace, clothed like a Persian queen, insisting that he should be addressed as Imperatrix, and quite living up to the title. It would not only be interesting, it would give one an insight into just how much the Romans could stand. It would have been curious, also, to have assisted at that superb and poetic ceremonial, in which, having got Tanit from Carthage as consort for Elagabal, he presided, girt with the pomp of church and state, over the nuptials of the Sun and Moon.
