It is reputed that Maso, called Giottino, of whom there will be mention below, was the son of this Stefano; and although many, by reason of the suggestiveness of the name, hold him the son of Giotto, I, by reason of certain records that I have seen, and of certain memoirs of good authority written by Lorenzo Ghiberti and by Domenico del Ghirlandajo, hold it as true that he was rather the son of Stefano than of Giotto. Be this as it may, returning to Stefano, it can be credited to him that he did more than anyone after Giotto to improve painting, for, besides being more varied in invention, he was also more harmonious, more mellow, and better blended in colouring than all the others; and above all he had no peer in diligence. And as for those foreshortenings that he made, although, as I have said, he showed a faulty manner in them by reason of the difficulty of making them, none the less he who is the pioneer in the difficulties of any exercise deserves a much greater name than those who follow with a somewhat more ordered and regular manner. Truly great, therefore, is the debt that should be acknowledged to Stefano, because he who walks in darkness and gives heart to others, by showing them the way, brings it about that its difficult steps are made easy, so that with lapse of time men leave the false road and attain to the desired goal. At Perugia, too, in the Church of S. Domenico, he began in fresco the Chapel of S. Caterina, which remained unfinished. [Illustration: _Berlin Photo. Co._ SS.
