More stress was laid on pure scholarship by Guarino of Verona (1370- 1460), who in the year 1429 was called to Ferrara by Niccolo d'Este to educate his son Lionello, and who, when his pupil was nearly grown up in 1436, began to teach at the university of eloquence and of the ancient languages. While still acting as tutor to Lionello, he had many other pupils from various parts of the country, and in his own house a select class of poor scholars, whom he partly or wholly supported. His evening hours till far into the night were devoted to hearing lessons or to instructive conversation. His house, too, was the home of a strict religion and morality. It signified little to him or to Vittorino that most of the humanists of their day deserved small praise in the matter of morals or religion. It is inconceivable how Guarino, with all the daily work which fell upon him, still found time to write translations from the Greek and voluminous original works.
Not only in these two courts, but generally throughout Italy, the education of the princely families was in part and for certain years in the hands of the humanists, who thereby mounted a step higher in the aristocratic world. The writing of treatises on the education of princes, formerly the business of theologians, fell now within their province.
