An acute and practiced eye might be able to trace, step by step, the increase in the number of complete men during the fifteenth century. Whether they had before them as a conscious object the harmonious development of their spiritual and material existence, is hard to say; but several of them attained it, so far as is consistent with the imperfection of all that is earthly. It may be better to renounce the attempt at an estimate of the share which fortune, character, and talent had in the life of Lorenzo il Magnifico. But look at a personality like that of Ariosto, especially as shown in his satires. In what harmony are there expressed the pride of the man and the poet, the irony with which he treats his own enjoyments, the most delicate satire, and the deepest goodwill!
When this impulse to the highest individual development was combined with a powerful and varied nature, which had mastered all the elements of the culture of the age, then arose the 'all-sided man' - 'l'uomo universale' - who belonged to Italy alone. Men there were of encyclopedic knowledge, in many countries during the Middle Ages, for this knowledge was confined within narrow limits; and even in the twelfth century there were universal artists, but the problems of architecture were comparatively simple and uniform, and in sculpture and painting the matter was of more importance than the form. But in Italy at the time of the Renaissance, we find artists who in every branch created new and perfect works, and who also made the greatest impression as men. Others, outside the arts they practiced, were masters of a vast circle of spiritual interests.
