A Child's History of England by Charles Dickens

King Edward the Second, the first Prince of Wales, was twenty-three years old when his father died. There was a certain favourite of his, a young man from Gascony, named Piers Gaveston, of whom his father had so much disapproved that he had ordered him out of England, and had made his son swear by the side of his sick-bed, never to bring him back. But, the Prince no sooner found himself King, than he broke his oath, as so many other Princes and Kings did (they were far too ready to take oaths), and sent for his dear friend immediately.

Now, this same Gaveston was handsome enough, but was a reckless, insolent, audacious fellow. He was detested by the proud English Lords: not only because he had such power over the King, and made the Court such a dissipated place, but, also, because he could ride better than they at tournaments, and was used, in his impudence, to cut very bad jokes on them; calling one, the old hog; another, the stage-player; another, the Jew; another, the black dog of Ardenne. This was as poor wit as need be, but it made those Lords very wroth; and the surly Earl of Warwick, who was the black dog, swore that the time should come when Piers Gaveston should feel the black dog's teeth.
