Meta Puzzle

Puzzle:

[Solution: Notice that the poem refers to the Last Supper (groups of three, Santa Maria delle Grazie, the religious plot that has followed our entire hunt). Each of the following slides refers to one puzzle, and connects it to the silhouette of one of the apostles. Puzzlers recall the previous puzzles and identify each puzzle answer as one of the apostles, and then match them up left to right. Each group of 3 apostles/puzzles and their answers, along with the Wordle grids, produce four new words: apery, cahen, gauss, piday, which reference four mathematical constants. Puzzlers take the first nonzero digit of each to get the code for the lock on the box, which contained the prizes for this hunt: 1683. As clued by the very end, puzzlers must go back to where they started—Mr. Davis's room—and find, under his desk, the box!]
