Explanation: Trajan is generally regarded as one of the better Emperors of the Roman Empire, in terms of civic conduct and military success.
When a certain king on the eastern frontier, I believe, screwed over one of Trajan’s plans by not fulfilling his treaty obligations, probably to provide troops or provisions or something. Trajan was fit to blow, and the king in question realized that he was screwed if Trajan’s fury came down on his head. So he sent his son, who was famously handsome, to apologize to Trajan, which Trajan apparently immediately took well - on account of it coming from a pretty young man. The prince then, after a diplomatic feast, danced for Trajan ‘in the barbarian manner’, and Trajan let the kingdom off the hook entirely.
Must have been one hell of a lap dance
