The present work is based on the Bust of an Old Man in the Museum der Bildenden Knste, Leipzig, Inv. no. 804. Recorded by the Rembrandt Research Committee as by an artist in Rembrandt's circle (possibly Paulus Lesire), that painting is dated to circa 1633, the same year in which the Dordrecht engraver Hendrik Dethier's etching of this figure, which he attributed to Rembrandt, was printed. This work and the present painting, in turn, paraphrase the figure of Saint Paul in Saint Paul at his writing-desk of circa 1629-30 in the Germanisches Nationalmuseum, Nuremberg, Inv. no. 392, dated by the Rembrandt Research Committee to 1629-30.
