“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. […] 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. The fifteenth century is above all that of the many-sided men. There is no biography which does not, besides the chief work of its hero, speak of other pursuits all passing beyond the limits of dilettantism.”
