The repentant Judas returns the money to the high priests to whom he betrayed Christ. This is derived from a work by the Dutch painter Rembrandt, although it is a different composition than the best-known painting he did of that subject in 1629.
Robert Dunkarton was a London mezzotint engraver active from 1770 to 1811. He began as a portrait painter, exhibiting at the Society of Artists and the Royal Academy between 1768 and 1779, whereupon he stopped exhibiting, presumably concentrating on engraving.
Benjamin Beale Evans (died c. 1824) was a London printseller and engraver, also associated with the renowned Boydells printsellers. Evans engraved the portraits of American participants at the Versailles peace congress in 1783.
