Two very important influences were wisely utilized by Charlemagne in his work of civilization, namely, the political ideas of the Teutons, and the adhering power of the Christian church. He cherished German customs, and left, in various parts of Germany, many monuments of his love for that people. He was of commanding presence, being seven feet in height, and of good proportions, blond in type, and of genial manners. His real capital was at Aix-la-Chapelle, but Rome was a nominal capital. Bulfinch says of Charlemagne: "Whether we regard him as a warrior or legislator, as a patron of learning or as the civilizer of a barbarous nation, he is entitled to our warmest admiration." If his successors had possessed the ability, enterprise, and breadth of view that characterized him, the world might never have known the period in history commonly called the "Dark Ages." =Personal Education.=--When Charlemagne arrived at the estate of manhood and ascended the throne, he was ignorant of letters and lacked any considerable intellectual training. His education had been that of the knight who believed that skill in the use of arms and physical prowess were of far more importance than a knowledge of letters.[39] After he had come to the throne, and especially after he had conquered his foes and had leisure to study the welfare of his people, he realized his deficiencies, and sought to overcome them by diligent study. He called to his court the most learned men of the world, received personal instruction from them, and had them read to him and converse with him while at his meals. In this way he overcame, in a measure, the defects of his early education. He thoroughly mastered Latin, became familiar with Greek, and learned also grammar, rhetoric, logic, music, astronomy, and natural history. He never learned to write well, owing to the late period of life at which he began, and to the clumsiness of the hand accustomed to wielding the sword rather than the pen. Among his instructors was _Alcuin of England_, the most celebrated teacher of his time. Charlemagne established the "School of the Palace," and placed Alcuin at its head. Here the children of the emperor as well as his courtiers were taught. He had his own daughters learn Latin and Greek. France is indebted to Alcuin for its polite learning. Alcuin was also the counselor of the emperor in the educational matters of the empire, and it was probably his influence that led Charlemagne to adopt such broad views concerning the culture of his people.
