"This picture is terrible for dark and effective expression; it is just one of those subjects in which the Caravaggio school delighted."—Jameson's Sacred Art.

33. Martyrdom of St. Peter: Guido Reni.

"This has the heavy powerful forms of Caravaggio, but wants the passionate feeling which sustains such subjects,—it is a martyrdom and nothing more,—it might pass for an enormous and horrible genre picture."—Kugler.

34. Martyrdom of St. Erasmus: N. Poussin. A most horrible picture of the disembowelment of the saint upon a wheel. It was copied in mosaic in St Peter's when the picture was removed from thence.

35. The Annunciation: Baroccio. From Sta. Maria di Loreto, detained in the Vatican in exchange for a mosaic, after it was sent back by the French.

36. St. Gregory the Great—the miracle of the Brandeum: Andrea Sacchi.

"The Empress Constantia sent to St. Gregory requesting some of the relics of St. Peter and St. Paul. He excused himself, saying that he dared not disturb their sacred remains for such a purpose,—but he sent her part of a consecrated cloth (Brandeum) which had enfolded the body of St. John the Evangelist. The empress rejected this gift with contempt: whereupon Gregory, to show that such things are hallowed not so much in themselves as by the faith of believers, laid the Brandeum on the altar, and after praying he took up a knife and pierced it, and blood flowed as from a living body."—Jameson's Sacred Art, p. 321.

37. The Ecstasy of Sta. Michelina: Baroccio. This picture is mentioned by Lanzi as "Sta. Michelina estatica sul Calvario." The story appears to be lost.
