Alessandro Nova. Letter to Keith Christiansen. July 21, 1989, bases the date of 1540 on the work's similarity to Romanino's organ shutters in San Giorgio in Braida, Verona, of that date; after having seen the work, believes that an assistant may have collaborated with Romanino on the reverse of the picture; mentions documents indicating that Alessandro Romanino collaborated with his cousin Girolamo on a processional banner made for the confraternity of Santa Maria delle Grazie e di San Girolamo, Brescia, in 1537, and others recording the existence of a Franciscan confraternity in Brescia.
Keith Christiansen in "Recent Acquisitions, A Selection: 1989–1990." Metropolitan Museum of Art Bulletin 48 (Fall 1990), pp. 36–37, ill. in color (obverse) and black and white (reverse) [repr. in "Master Paintings," exh. cat., Algranti, London, 1994, unpaginated, unnumbered, ill. (color, obverse)], dates it about 1540, "shortly after his fresco cycle in the village of Pisogne"; calls it a processional standard made for a Franciscan lay confraternity and "probably removed from its original location . . . following the Napoleonic suppression of religious orders in Italy"; states that the obverse was painted entirely by Romanino but that the reverse reveals workshop participation; suggests that the figures of the torturers may be influenced by Dürer's prints and that the figure of Christ may be inspired by Hans Baldung Grien's woodcut of Christ at the column; notes that Caravaggio later made reference to the figure of Christ in his painting of the same subject of 1607 (Museo di Capodimonte, Naples), and that Caravaggio's familiarity with the work supports the hypothesis that it was made for a major Brescian church such as San Francesco.
