was to be completed. In this instance he had to paint not on a flat surface but on a semicircular one; and the correspondence of the squares which the curved lines of the net formed on the concave surface, with the straight ones of the sketch, together with accuracy in the architectural proportions which were to be brought forward in perspective, could not be otherwise obtained than by that simple and ingenious contrivance. I was cautious enough not to step before the taper, lest I might betray myself by my shadow, but I stood near enough to his side to observe the painter closely. He appeared to me quite another man. Perhaps it was the effect of the taper, but his face had a good colour, his eyes sparkled with internal satisfaction, and when he had completed the lines he placed himself before the screen, with his hands resting on his sides, and looking at his work, whistled a merry tune. He now turned round, and tore down the net. Suddenly he was struck by my figure, and cried aloud:
"Halloah! halloah! is that you, Christian?"
I went up to him, explained how I had been attracted into the church, and praising the ingenious contrivance of the net, gave him to understand that I was but a connoisseur and practiser of the noble art of painting. Without making me any further answer, Berthold said:
"Christian is neither more nor less than a sluggard. He was to have kept with me faithfully through the whole night, and now he is certainly snoring somewhere! I must get on with my work, for probably it will be bad to paint here on the screen to-morrow—and yet I can do nothing by myself."
I offered my assistance, upon which he laughed aloud, laid hold of both my shoulders, and cried:
"That is a capital joke! What will Christian say, when he finds to-morrow that he is an ass, and that I have done without him? So, come hither, stranger, help me to build a little."
He lit several tapers, we ran through the church, pulled together a number of blocks and planks, and a lofty scaffold was soon raised within the screen.
"Now hand up quickly," cried Berthold, as he ascended.
I was astonished at the rapidity with which Berthold made a large copy of the drawing; he drew his lines boldly, and always clearly and correctly, without a single fault. Having been accustomed to such matters in my early youth, I was of good service to him, for standing, now above him, now below him, I fixed the long rulers at the points he indicated, and held them fast, pointed the charcoal, and handed it to him, and so on.
"You are a capital assistant," cried Berthold, quite delighted.
"And you," I retorted, "are one of the best architectural painters possible. But tell me, have you applied your bold, ready hand to no sort of painting but this?—Pardon the question."
"What do you mean?" said Berthold.
"Why, I mean," replied I, "that you are fit for something better
