One more jigsaw puzzle touched by the malign hand of Jarvis

The jigsaw portraying the ceiling of the Sistine Chapel called for special measures. Yasemin created a numbering system for the alcoves and sorted through the thousand pieces so we could assemble the basic structure. This was a lesson in art education, as we labelled the characters in the painting and examined a clearer image she found online. Alas, Jarvis never misses a trick. Once more he switched a single piece. The last one to go in wouldn't fit because it was from another puzzle.
