A drawing of the Crucifixion, with the Virgin fainted at the foot of the Cross, and two figures bringing in a ladder from the right. 

As noted on the old mount by Sir Richard Holmes, Royal Librarian, a large miniature by Apollonio de’ Bonfratelli (a pupil of Giulio Clovio) to this design is among an album of fragments in the British Library (MS Add. 21412, f.39.9). The fragment was cut from a choral book bearing the inscription: ‘Apollonius de Bonfratellis de Capranica / Capellae et Sacristiae Apostolicae miniator / fecit anno Domini MDLXIV / sedente Pio IV Pontif. Opt. Max. / de Medicis Mediolanense’.

The same characters are present in a miniature with the Four Evangelists at the Morgan Library, New York: ‘Gregorius XIII / Pontifex Optimus Maximus / Boncompagnus Bononiensis / Electus anno Domini MDLXXIII’. In the Free Library at Philadelphia is a small miniature of St Luke (M 27:7, J.F. Lewis collection), attributed to Apollonio by M. Harrsen ('Mediaeval and Renaissance Miniatures in the J. F. Lewis Collection in Philadelphia', in Scriptorium, XIV, 1960).

H. Bodmer had suggested Prospero Fontana as the draughtsman, but there is no reason for supposing that it is not Bonfratelli’s own design for his miniature.
