Now, the trouble of Patrasche was this. Into these great, sad piles of stones, that reared their melancholy majesty above the crowded roofs, the child Nello would many and many a time enter, and disappear through their dark arched portals, whilst Patrasche, left without upon the pavement, would wearily and vainly ponder on what could be the charm which thus allured from him his inseparable and beloved companion. Once or twice he did essay to see for himself, clattering up the steps with his milk-cart behind him; but thereon he had been always sent back again summarily by a tall custodian in black clothes and silver chains of office; and fearful of bringing his little master into trouble, he desisted, and remained couched patiently before the churches until such time as the boy reappeared. It was not the fact of his going into them which disturbed Patrasche: he knew that people went to church: all the village went to the small, tumbledown, gray pile opposite the red windmill. What troubled him was that little Nello always looked strangely when he came out, always very flushed or very pale; and whenever he returned home after such visitations would sit silent and dreaming, not caring to play, but gazing out at the evening skies beyond the line of the canal, very subdued and almost sad. What was it? wondered Patrasche. He thought it could not be good or natural for the little lad to be so grave, and in his dumb fashion he tried all he could to keep Nello by him in the sunny fields or in the busy market-place. But to the churches Nello would go: most often of all would he go to the great cathedral; and Patrasche, left without on the stones by the iron fragments of Quentin Matsys's gate, would stretch himself and yawn and sigh, and even howl now and then, all in vain, until the doors closed and the child perforce came forth again, and winding his arms about the dog's neck would kiss him on his broad, tawney-colored forehead, and murmur always the same words: "If I could only see them, Patrasche!--if I could only see them!" What were they? pondered Patrasche, looking up with large, wistful, sympathetic eyes. One day, when the custodian was out of the way and the doors left ajar, he got in for a moment after his little friend and saw. "They" were two great covered pictures on either side of the choir.
