But the Rhodians on their part made a vigorous resistance, and Demetrius, although he was accomplishing nothing worthy of mention, nevertheless kept up the fight against them in a rage, because, when Phila his wife sent him letters, bedding, and clothing, the Rhodians had captured the vessel containing them, and had sent it, just as it was, to Ptolemy. In this they did not imitate the considerate kindness of the Athenians, who, having captured Philip’s letter-carriers when he was making war upon them, read all the other letters, indeed, but one of them, which was from Olympias, they would not open; instead, they sent it back to the king with its seal unbroken. However, although Demetrius was exceedingly exasperated by this when the Rhodians soon after gave him a chance to retaliate, he would not allow himself to do so. It happened, namely, that Protogenes the Caunian had been making a painting for them which illustrated the story of Ialysus, and this picture, nearly finished, had been captured by Demetrius in one of the suburbs of the city. The Rhodians sent a herald and, begged Demetrius to spare and not destroy the work, whereupon he replied that he would rather burn the likenesses of his father than so great a labour of art.
