[Charles’ Education] Charles had the gift of ready and fluent speech, and could express whatever he had to say with the utmost clearness. He was not satisfied with command of his native language merely, but gave attention to the study of foreign ones, and in particular was such a master of Latin that he could speak it as well as his native tongue; but he could understand Greek better than he could speak it.
