All through the Thirteenth Century this characteristic will be found that genius did not as a rule lack appreciation. The greater the revolution a genuinely progressive thinker and worker tried to accomplish in human progress, the more sure was he to obtain not only a ready audience, but an enthusiastic and encouraging following. This is the greatest compliment that could be paid to the enlightenment of the age. Men's minds were open and they were ready and willing to see things differently from what they had been accustomed to before. This constitutes after all the best possible guarantee of progress. It is, however, very probably the last thing that we would think of attributing to these generations of the Thirteenth Century, who are usually said very frankly to have been wrapped up in their own notions, to have been only too ready to accept things on authority rather than by their own powers of observation and judgment, and to have been clingers to the past rather than lookers to the present and the future. Giotto's life shows better than any other how much this prejudiced view of the Thirteenth Century and perforce of the Middle Age needs to be corrected. During forty years Giotto responded to every demand, and made himself suffice for every call, worked in nearly every important city of Italy, enkindling everywhere he went the new light of art. Before the end of the century he completed a cartoon for the famous picture of the Boat of Peter which was to adorn the Facade of St. Peter's. He was in Rome in 1300, the first jubilee year, arranging the decorations at St. John Lateran. The next year he was at Florence, working in the Palace of the Podesta. And so it went for full two score years. He was at Pisa, at Lucca, at Arezzo, at Padua, at Milan, then he went South to Urbino, to Rome and then even to Naples. Unfortunately the strain of all this work proved too much for him and he was carried away at the comparatively early age of sixty in the midst of his artistic vigor and glory. {opp147} [Illustration] ESPOUSAL OF ST.
