The Good Samaritan, Rembrandt van Rijn
OK, so the defecating dog was a source of some amusement back in art school, but once you get past that, this etching is just mind-bogglingly superb — a tour-de-force of drawing and the mediums of etching and drypoint.
This was made after one of Rembrandt’s own paintings (though there is some question as to whether the painting is entirely by Rembrandt’s hand). The painting, also titled The Good Samaritan, is in the Wallace Collection in London.
This copy of the etching is in the Metropolitan Museum of Art (more info here). It is on a sheet roughly 10×8″ (26x21cm).
Since the etching was drawn from the painting, and then printed, we see a reverse image of the painting. Where the dog came from, I don’t know — neither it nor the other foreground elements appear in the painting — but Rembrandt loved to pick up on those little everyday details of life in his drawings and etchings.
