LI. Demetrius now despatched letters to his son, and to the commanders of his garrisons at Athens and Corinth, warning them not to pay any attention to any despatches which they might receive in his name, or even to his royal signet, but to regard him as practically dead, and to hold the cities in trust for his heir Antigonus. His son was much grieved at hearing of his father's capture, put on mourning, and sent letters to all the other kings, and to Seleukus himself, begging for his father's liberation. He offered to give up all the places which he still held, and even proposed to surrender himself as a hostage in place of his father. Many cities and princes supported his request, except Lysimachus, who offered to give Seleukus a large sum of money if he would put Demetrius to death. But Seleukus, who had always disliked Lysimachus, now regarded him with abhorrence as a savage villain, and still continued to keep Demetrius in captivity, under the pretext that he was waiting for the arrival of his son Antiochus and Stratonike, that they might have the pleasure of restoring him to liberty. LII. Demetrius at first bore up manfully against his misfortunes, and learned to endure captivity, taking exercise as well as he could, by hunting in the park, and by running; but, little by little, he neglected these amusements, addicted himself to drinking and dicing, and thus spent most of his time; either in order to escape from the thoughts of his present condition by intoxication, or else because he felt that this was the life which he had always wished to lead, and that he had caused great suffering both to himself and to others by fighting by sea and land in order to obtain that comfort which he had now unexpectedly discovered in repose and quiet. What, indeed, is the object of the wars and dangers which bad kings endure, in their folly, unless it be this? although they not only strive after luxury and pleasure, instead of virtue and honour, but do not even understand in what real luxury and enjoyment consist. Be that as it may, Demetrius, after living in confinement in the Chersonese for three years, died of laziness, surfeit and over-indulgence in wine, in the fifty-fourth year of his age.[322] Seleukus was greatly blamed for the suspicions which he had entertained about Demetrius, and greatly repented that he had not imitated the wild Thracian Dromichætes, who dealt so kindly and royally with Lysimachus when he had taken him prisoner.
