Abraham and Isaac
by COECKE VAN AELST, Pieter, Pen, brown ink, black chalk, 235 x 386 mm
The foreground of this drawing was executed in pen and ink, and the rest of it in black chalk. The main scene of the Old Testament story in which Isaac is about to be sacrificed on the hilltop is missing since it was painted over with wash imitating clouds either by the artist himself or someone else.
