Several pieces of paper have been glued to the original support by the artist in order to correct the original lines of certain parts of the composition (the angel’s shoulder and Abraham’s head). Isaac appears at the right, lying seminude and blindfolded on the pyre of trunks. Abraham brandishes a knife in his right hand, holding his son’s head with the left and turning to look at the young angel who rests his left hand on the patriarch’s shoulder. With his right, the angel points to the lamb caught in the brambles at the left of the composition (Text from Pérez Sánchez, A. E.: Dibujos españoles, siglos XV-XVII, 1972, pp. 47-48).
