Plutarch Demetrius 50

[1] When Seleucus heard of it, he declared that it was not the good fortune of Demetrius that brought him safety, but his own, which, in addition to her other blessings, gave him an opportunity to show generosity and kindness. Then he called his overseers and bade them pitch a royal tent, and to make all other arrangements and preparations for a magnificent reception and entertainment.

[2] There was also with Seleucus a certain Apollonides, who had been an intimate friend of Demetrius; this man was at once sent to him by Seleucus, to give him cheerfulness and confidence by reminders that he was coming into the presence of a man who was a friend and relative. When this purpose of Seleucus became evident, first a few of his friends, then the greater part of them, went off hot foot to Demetrius, vying with one another in their efforts to reach him first; for it was expected that he would at once be a very great personage at the court of Seleucus.

[3]
  But this behaviour of his friends turned the king’s pity into jealousy, and gave malicious and mischievous persons an opportunity to thwart and put an end to his generosity. They frightened him by their insinuations that without any delay, but at the first sight of Demetrius, there would be a great revolution in the camp.

[4] And so it came to pass that at the very time when Apollonides had come to Demetrius with a joyful countenance, and while the other courtiers were coming up and telling him wonderful tales about Seleucus and his generosity, and when Demetrius, after all his disasters and misfortunes, even if he had once thought his surrender a disgraceful act, had now changed his mind as a result of his courage and hopefulness, up came Pausanias at the head of a thousand soldiers, foot and horse together.

[5] With these he surrounded Demetrius on a sudden, and after sending off everybody else, conducted him, not into the presence of Seleucus, but away to the Syrian Chersonese. Here, for the rest of his life, a strong guard was set over him, a sufficient number of attendants came to him from Seleucus, while money and maintenance was provided for him day by day which was not to be despised, nay, royal courses for riding and walking, and parks with wild game in them, were set apart for his use;

[6] any friend also who shared his exile and wished to visit him could do so, and notwithstanding his captivity sundry people kept coming to him from Seleucus bringing kindly messages and exhorting him to be of good cheer, since as soon as Antiochus came with Stratonicé, he was to be set at liberty.
