Excellent

"Excellent," said Tiberius, drily, "and now what about your own?"
Thrasyllus made another set of calculations, and then looked up in real or pretended terror. "Great Heavens!" he exclaimed, "an appalling danger threatens me from air and water."
"Any chance of circumventing it?" asked Tiberius.
"I cannot say. If I could survive the next twelve hours, my fortune would be, in its degree, as happy even as yours; but nearly all the malevolent planets are in conjunction against me and the danger seems all but unavoidable. Only Venus can save me."
"What was that you said just now about her? I forget."
"That she is moving into Scorpio, which is your sign, portending a marvellously happy change in your fortunes. Let me venture a further deduction from this all-important movement: you are soon to be engrafted into the Julian house, which, I need hardly remind you, traces direct descent from Venus, the mother of Eneas. Tiberius, my humble fate is curiously bound up with your illustrious one. If good news comes to you before dawn tomorrow, it is a sign that I have almost as many fortunate years before me as yourself."
They were sitting out on the porch and suddenly a wren or some such small bird hopped on Thrasyllus's knee and, cocking its head on one side, began to chirp at him. Thrasyllus said to the bird, "Thank you, sister! It came only just in time." Then he turned to Tiberius: "Heaven be praised! That ship has good news for you, the bird says, and I am saved. The danger is averted."
Tiberius sprang up and embraced Thrasyllus, confessing what his intentions had been. And, sure enough, the ship carried Imperial dispatches from Augustus informing Tiberius of Lucius's death and saying that in the circumstances he was graciously permitted to return to Rome, though for the present only as a private citizen.
As for Gaius, Augustus had been anxious that he should have no task assigned to him for which he was not fitted, and that the East should remain quiet during his governorship. Unfortunately the King of Armenia revolted and the King of Parthia threatened to join forces with him; which put Augustus in a quandary. Though Gaius had shown himself an able peace-time governor, Augustus did not believe him capable of conducting so important a war as this; and he himself was too old to go campaigning and had too many affairs to attend to at Rome, besides. Yet he could not send out anybody else to take over the Eastern regiments from Gaius because Gaius was Consul and should never have been allowed to enter upon the office if he was incapable of high military command. There was nothing to be done but to let Gaius be and hope for the best.
Gaius was lucky at first. The danger from the Armenians was removed by an invasion of their Eastern border by a wandering tribe of barbarians. The King of Armenia was killed while chasing them away. The King of Parthia, hearing of this and also of the large army that Gaius was getting together, then came to terms with him: to the great relief of Augustus. But Augustus's new nominee to the throne of Armenia, a Mede, was not acceptable to the Armenian nobles, and when Gaius had sent home his extra forces as no longer necessary they declared war after all. Gaius reassembled his army, and marched to Armenia, where a few months later he was treacherously wounded by one of the enemy generals who had invited him to a parley. It was not a serious wound. He thought little of it at the time and concluded the campaign successfully. But somehow he was given the wrong medical treatment, and his health, which from no apparent cause had been failing him for the last two years, became seriously affected: he lost all power of mental concentration. Finally he wrote to Augustus for permission to retire into private life. Augustus was grieved, but granted his plea. Gaius died on his way home. Thus of Julia's sons only fifteen year old Postumus now remained and Augustus was so far reconciled to Tiberius that, as Thrasyllus foretold, he engrafted him into the Julian house by adopting him, jointly with Postumus, as his son and heir.
