53. But why should four unfortunate masters be dropped out?

Well, I want to drop them out, at any rate; but not in disrespect. In hope, on the contrary, to make you remember them very separately indeed;—for this following reason.

We are in the careless habit of speaking of men who form a great number of pupils, and have a host of inferior satellites round them, as masters of great schools.

But before you call a man a master, you should ask, Are his pupils greater or less than himself? If they are greater than himself, he is a master indeed;—he has been a true teacher. But if all his pupils are less than himself, he may have been a great man, but in all probability has been a bad master, or no master.

Now these men, whom I have signally left out of my groups, are true Masters.

Niccola Pisano taught all Italy; but chiefly his own son, who succeeded, and in some things very much surpassed him.

Orcagna taught all Italy, after him, down to Michael Angelo. And these two—Lippi, the religious schools, Verrocchio, the artist schools, of their century.
