Einhard (–840)

He was ready and fluent in speaking, and able to express himself with great clearness. He did not confine himself to his native tongue, but took pains to learn foreign languages, acquiring such knowledge of Latin that he could make an address in that language as well as in his own. Greek he could better understand than speak. Indeed, he was so polished in speech that he might have passed for a learned man.

He was an ardent admirer of the liberal arts, and greatly revered their professors, whom he promoted to high honors. In order to learn grammar, he attended the lectures of the aged Peter of Pisa, a deacon; and for other branches he chose as his preceptor Albinus, otherwise called Alcuin, also a deacon, - a Saxon by race, from Britain, the most learned man of the day, with whom the king spent much time in leaving rhetoric and logic, and more especially astronomy. He learned the art of determining the dates upon which the movable festivals of the Church fall, and with deep thought and skill most carefully calculated the courses of the planets. Charles also tried to learn to write, and used to keep his tablets and writing book under the pillow of his couch, that when he had leisure he might practice his hand in forming letters; but he made little progress in this task, too long deferred and begun too late in life.
