CHAPTER IV.
Sejanus, when left alone, motioned to the two troopers. He who had brought Tiberius his horse rode furiously after the Cæsar; the other attended the general, who slowly mounted his own steed, and, pursuing the same direction, began to trot leisurely toward Formiæ. The sun had gone down; the short twilight had passed away; clouds had gathered, and the moon, not having yet risen, the night was very black. In a few minutes Sejanus slackened his horse's pace from a trot to a walk, and the orderly, as his military attendant would in modern times be called, nearly rode against him in the dark. The man made some natural excuse, and fell back again about thirty paces.
Sejanus hardly noticed him.
"At present," he muttered, when again alone, "Tiberius, though a Cæsar, needs me; Germanicus is Cæsar too, and may become emperor. If Germanicus wished it, right or wrong—if per fas et nefas—he would win. He has much of the genius of Caius Julius and his defect of overtrustfulness; but none of his many vices. I doubt if he will ever be emperor; he is too Athenian, and also too honorable, too disinterested. Somehow I feel, too, as if he were going to be assassinated; he believes readily in men. Tiberius has smaller abilities, worse qualities, and better chances. He will rule the world, and Ælius Sejanus will rule him."
As Sejanus said these things to himself in an indistinct murmur, of which none could have heard the precise words, a voice at his elbow astonished him. Said the voice,
"How far is it, illustrious general, to Formiæ?"
The prætorian chief turned with a start, and saw that the speaker was a mounted traveller, attended by two servants, also on horseback; but there was so little light that he could not distinguish the stranger's features, nor more of his dress and appointments than that they were not, as it seemed, Italian.
"About five thousand paces," he answered. "However, there is no inn at Formiæ. Some eight hundred paces from here is a good wayside tavern, (mansio.) But you call me general, for I wear the dress. You do not, however, know me."
"Not know the distinguished chief of the prætorians? Not know the happy and unhappy, the fortunate and unfortunate Sejanus?"
