The Last of the Barons, Book III by Edward Bulwer-lytton

William Lord Hastings was one of the most remarkable men of the age. Philip de Comines bears testimony to his high repute for wisdom and virtue. Born the son of a knight of ancient lineage but scanty lands, he had risen, while yet in the prime of life, to a rank and an influence second, perhaps, only to the House of Nevile. Like Lord Montagu, he united in happy combination the talents of a soldier and a courtier. But as a statesman, a schemer, a thinker, Montagu, with all his craft, was inferior to Hastings. In this, the latter had but two equals, -- namely, George, the youngest of the Nevile brothers, Archbishop of York; and a boy, whose intellect was not yet fully developed, but in whom was already apparent to the observant the dawn of a restless, fearless, calculating, and subtle genius.

That boy, whom the philosophers of Utrecht had taught to reason, whom the lessons of Warwick had trained to arms, was Richard, Duke of Gloucester, famous even now for his skill in the tilt-yard and his ingenuity in the rhetoric of the schools.
