But although the allegorical element in the poetry, the art, and the festivals of Italy is superior both in good taste and in unity of conception to what we find in other countries, yet it is not in these qualities that it is most characteristic and unique. The decisive point of superiority lay rather in the fact that, besides the personifications of abstract qualities, historical representatives of them were introduced in great number - that both poetry and plastic art were accustomed to represent famous men and women. The 'Divine Comedy,' the 'Trionfi' of Petrarch, the 'Amorosa Visione' of Boccaccio - all of them works constructed on this principle - and the great diffusion of culture which took place under the influence of antiquity, had made the nation familiar with this historical element. These figures now appeared at festivals, either individualized, as definite masks, or in groups, as characteristic attendants on some leading allegorical figure. The art of grouping and composition was thus learnt in Italy at a time when the most splendid exhibitions in other countries were made up of unintelligible symbolism or unmeaning puerilities.
