IV

Right above the scaffolding of the unfinished cathedral, up a narrow stair of rope to one of the slender pinnacles, not far from the principal tower, a certain young mason clomb, bearing a small statue of St. Catharine, to be fixed on the very top of the little spire. Around him rose a perfect forest of pinnacles, sharp-pointed like stalactites; spires, flying arches, stone lacework of unexampled flowers and foliage, prophets, martyrs, and angels, the grinning masks of devils, monstrous birds, sirens, harpies, dragons with scaly wings and gaping mouths, every sort of gargoyle at the terminals of the water-pipes. All was of marble very pure and white, upon which the shadows showed blue as smoke, the whole suggesting a winter wood clothed in sparkling frost. It was quiet, save that the swallows and swifts made joyous cries as they continually circled above and around the building. The hum of the crowd in the square reached the young mason like the low murmur of an ant-hill. At times he fancied organ-notes and prayerful sighs rose from the interior of the temple as from the depth of its stony heart; and then it seemed as if the whole vast edifice breathed and grew and heaved to the sky like the eternal praise of the birth of Mary; like the glad hymn of all ages and of all peoples to the Immaculate Virgin.

Suddenly the hum from the square increased in volume, and an uproar became plain to the ear. The mason paused in his work and looked down. Then his head swam and his eyes grew dim. He felt the edifice rocking under him, and the slender pinnacle towards which he was climbing bent like a reed.

'It is all over!' he said. 'I am falling. Lord receive my spirit.'

He clung desperately to the rope, closed his eyes, and murmured:—

'Ave Maria, piena di grazia.'

Then he felt more at ease. From above swept a breath of cool wind; he recovered himself, collected his strength and climbed higher, listening no longer to the humming of earth, but ascending towards the serene and quiet heaven, saying with great unction:—

'Ave, dolce Maria, di grazia piena.'

At this moment, traversing the broad marble roof, came the members of the building committee, Council of the Fabric, architects both native and foreign, summoned by the duke to consult about the Tiburio, the principal tower, which was to rise even higher than the cupola. Among them was Leonardo da Vinci; he had submitted his plan, but the council had rejected it as too daring, too extravagant, and not sufficiently in accord with the traditions of church architecture. The council quarrelled over the matter, and could not arrive at an agreement. Some said the building had been commenced by ignorant people, and that the inner columns were not stable enough to carry the Tiburio and all the lesser towers and pinnacles. According to others the cathedral was like to stand firm till Doomsday.

Leonardo took no part in the dispute, but stood aside, silent and alone. One of the workmen approached and handed him a letter.

'Messere,' he said, 'it has been brought to Your Magnificence by a messenger from Pavia.'

Leonardo read the letter:—

'Leonardo, I need thee. Come to me at once. October 14.
Gian Galeazzo, the Duke.'

The Master excused himself to his fellow-councillors, descended to the square, mounted, and rode off to the Castle of Pavia, a few hours' distant from Milan.
