A drawing of the Mystic Marriage of St Catherine, the Virgin and Child with the infant St John the Baptist on the left, St Catherine kneeling on the right, St Joseph standing in the background. Inscribed at lower centre in an old hand: 'di Federico Zuccaro'.

Bodmer (note on mount) attributed the drawing to Sammacchini. Popham (in P&W) noted a related painting at Dresden (inv. 117) of the same subject then attributed to Sammacchini (perhaps the basis of Bodmer's attribution); a drawing at Budapest by the same hand attributed to Bagnacavallo; and another in the British Museum that he supposed was by the same hand, with an old attribution to Pompeo Cesura dell'Aquila (SL,5223.47; Gere and Pouncey 235, as a copy after PCdA). On that basis Popham attributed both the present drawing and the Dresden painting to Cesura dell'Aquila. 

In his review of P&W, F. Antal attributed the drawing to the Veronese school (Burlington Magazine, 1951, p.32). More recently the drawing has been attributed to Pellegrino Tibaldi (Blunt (Misc), p.74); and to Bagnacavallo (U.V. Fischer Pace, correspondence, 1973; P.L. Leone de Castris, orally, 2000), an attribution that seems convincing.
