Not for the easily spooked, the crypt under the Church of Santa Maria della Concezione holds the bones of some 4,000 dead Capuchin monks. Arranged in odd decorative designs around the shriveled and decayed skeletons of their kinsmen, a macabre reminder of the impermanence of earthly life, the crypt is strangely touching and beautiful. As one sign proclaims: "What you are, we once were. What we are, you someday will be." After a recent renovation, the crypt was reopened to the public with a new museum devoted to teaching visitors about the Capuchin order; the crypt is now located at the end of the museum circuit. Upstairs in the church, the first chapel on the right contains Guido Reni's mid-17th-century St. Michael Trampling the Devil. The painting caused great scandal after an astute contemporary observer remarked that the face of the devil bore a surprising resemblance to the Pamphili Pope Innocent X, archenemy of Reni's Barberini patrons. Compare the devil with the bust of the pope that you saw in the Palazzo Doria Pamphilj and judge for yourself.
