When they had climbed the attic ladder (they called it 'the mainmast tree', out of the ballad of Sir Andrew Barton, and Dan 'swarved it with might and main', as the ballad says) they saw a man sitting on Duck Window-sill. He was dressed in a plum-coloured doublet and tight plum-coloured hose, and he drew busily in a red-edged book. 'Sit ye! Sit ye!' Puck cried from a rafter overhead. 'See what it is to be beautiful! Sir Harry Dawe--pardon, Hal--says I am the very image of a head for a gargoyle.' The man laughed and raised his dark velvet cap to the children, and his grizzled hair bristled out in a stormy fringe. He was old--forty at least--but his eyes were young, with funny little wrinkles all round them. A satchel of embroidered leather hung from his broad belt, which looked interesting. 'May we see?' said Una, coming forward. 'Surely--sure-ly!' he said, moving up on the window-seat, and returned to his work with a silver-pointed pencil. Puck sat as though the grin were fixed for ever on his broad face, while they watched the quick, certain fingers that copied it. Presently the man took a reed pen from his satchel, and trimmed it with a little ivory knife, carved in the semblance of a fish. 'Oh, what a beauty!' cried Dan. ''Ware fingers! That blade is perilous sharp. I made it myself of the best Low Country cross-bow steel. And so, too, this fish. When his back-fin travels to his tail--so--he swallows up the blade, even as the whale swallowed Gaffer Jonah ... Yes, and that's my ink-horn. I made the four silver saints round it. Press Barnabas's head. It opens, and then----' He dipped the trimmed pen, and with careful boldness began to put in the essential lines of Puck's rugged face, that had been but faintly revealed by the silver-point. The children gasped, for it fairly leaped from the page. As he worked, and the rain fell on the tiles, he talked--now clearly, now muttering, now breaking off to frown or smile at his work. He told them he was born at Little Lindens Farm, and his father used to beat him for drawing things instead of doing things, till an old priest called Father Roger, who drew illuminated letters in rich people's books, coaxed the parents to let him take the boy as a sort of painter's apprentice. Then he went with Father Roger to Oxford, where he cleaned plates and carried cloaks and shoes for the scholars of a College called Merton. 'Didn't you hate that?' said Dan after a great many other questions. 'I never thought on't. Half Oxford was building new colleges or beautifying the old, and she had called to her aid the master-craftsmen of all Christendie--kings in their trade and honoured of Kings. I knew them. I worked for them: that was enough. No wonder----' He stopped and laughed. 'You became a great man, Hal,' said Puck. 'They said so, Robin. Even Bramante said so.' 'Why? What did you do?' Dan asked.
