While he was acquiring this knowledge he was also learning a language,
the one language besides his own which to a Roman was worth
knowing--Greek. Very possibly he had begun to pick it up in the nursery,
where a Greek slave girl was to be found, just as the French _bonne_ or
the German nursery-governess is among our own wealthier families. He

illustrate his victories. He added to the commission a stipulation that
the artist should also be qualified to take the place of tutor. By good

diligently than before; he had books read to him night and day. These
were studies which he could pursue without his eyes; but he also, and
this seems almost incredible, taught geometry without them, instructing
