A very rare drawing by the Florentine artist, Cosimo Gamberucci, this sheet is preparatory for his painting in the Florentine, Certosa di Galluzzo, dated to 1610 (fig. 1). Gamberucci was an apprentice in the workshop of Santi di Tito and remained mostly faithful to his master's style for his entire career.
We are grateful to Enrico Cortona for this attribution and for suggesting the connection to the Martyrdom of Saint Andrew, at Galluzzo.
