Once attributed to Petrus Christus (1410-1472/73), this drawing on vellum has since been reassigned to an artist in the Circle of Jan van Eyck. It is one of two extant drawings in a series of the twelve Apostles. The vellum is so transparent that it is conceivable that the straight pen lines defining the contours and folds of the drapery were traced from a model and the hatching filled in afterward with point of brush. It is likely that the Lehman drawing and its prototype related to a painting, possibly a grisaille painting, rather than to sculpture.
