“It lacks still two hours of noon,” said the sculptor to his friend, as they stood under the arch of the gateway, waiting for their passports to be examined; “will you come with me to see some admirable frescos by Perugino?  There is a hall in the Exchange, of no great magnitude, but covered with what must have been—­at the time it was painted—­such magnificence and beauty as the world had not elsewhere to show.”

“It depresses me to look at old frescos,” responded the Count; “it is a pain, yet not enough of a pain to answer as a penance.”

“Will you look at some pictures by Fra Angelico in the Church of San Domenico?” asked Kenyon; “they are full of religious sincerity, When one studies them faithfully, it is like holding a conversation about heavenly things with a tender and devout-minded man.”

“You have shown me some of Fra Angelico’s pictures, I remember,” answered Donatello; “his angels look as if they had never taken a flight out of heaven; and his saints seem to have been born saints, and always to have lived so.  Young maidens, and all innocent persons, I doubt not, may find great delight and profit in looking at such holy pictures.  But they are not for me.”

It happened to be market day in Perugia.  The great square, therefore, presented a far more vivacious spectacle than would have been witnessed in it at any other time of the week, though not so lively as to overcome the gray solemnity of the architectural portion of the scene.  In the shadow of the cathedral and other old Gothic structures—­seeking shelter from the sunshine that fell across the rest of the piazza—­was a crowd of people, engaged as buyers or sellers in the petty traffic of a country fair.  Dealers had erected booths and stalls on the pavement, and overspread them with scanty awnings, beneath which they stood, vociferously crying their merchandise; such as shoes, hats and caps, yarn stockings,
