Vittorino found it difficult to govern his school at Padua as strictly as he wished. The public Gymnasium was ill-ordered, and great license of life was permitted to its students. He therefore removed to Venice in 1423, where he continued his work as private tutor. By this time, however, he had acquired considerable reputation as an educator, to whose care the youth of both sexes might be entrusted with implicit confidence--no small testimony to his goodness in that age of ungoverned passions and indescribable vices. The Marchese Gian Francesco Gonzaga was looking out for a master for his children, and his choice fell on Vittorino. The admiration of antiquity was no mere matter of fashion with this prince. He loved history for its own sake, and professed a special reverence for the Roman Camillus. His practical good sense made him understand that, if he wished his sons and daughters to become thoroughly educated, not only in the humanities and mathematics, but also in the republican virtues of the ancients, which then formed the ideal of life in Italy, he must be willing to commit them wholly to the charge of their appointed governor. Vittorino, who would have undertaken the duty on no other condition, obtained full control of the young princes and their servants. An appointment of twenty sequins per month was assigned to him, together with a general order on the treasury of Mantua. A villa, called Casa Zojosa, which we may translate Joyous Gard, was allotted to the new household, and there Vittorino established himself as master in 1425. He had much to do before this dwelling could be converted from the pleasure house of a mediæval sovereign into the semi-monastic resort of earnest students. Through its open galleries and painted banquet chambers the young Gonzaghi lounged with favourite friends selected from the Mantuan nobility. The tables groaned under gold and silver plate, while perfumed lacqueys handed round rich wines and highly seasoned dishes, and the garden alleys echoed to the sound of lute and viol. Without making any brusque or sudden reformation, Vittorino managed, by degrees, and on various pretexts, to dismiss the more dangerous friends and servants of his pupils. A strict house-porter was engaged, with orders to exclude suspicious visitors. Plain clothes, simple habits, and frugal meals became the rule of the household, Vittorino contriving to render these changes no less agreeable than salutary to his pupils. When complaints arose from the former companions of the princes and their parents, he laid his plan of training clearly before the Marquis, who had the good sense to approve of all that he had done.
