In the 20th century, Jean-Léon Gérôme depicted Androcles in a painting tentatively dated 1902 and now in the Museo Nacional de Bellas Artes (Buenos Aires). There Androcles is sitting cross-legged on the floor of the cave as he draws the thorn from the lion's paw while it roars in agony. Briton Riviere's 1908 painting of him standing to perform the same task is in the Auckland Art Gallery. Another approach was to show the earlier incident of Androcles surprised in the cave by the lion's entrance. This was the subject chosen by Vassily Rotschev (d.1803) soon after returning to Russia from training in Rome. It was also the choice of the Chinese painter Xu Beihong. His "Slave and Lion" dates from a stay in Berlin during the early 1920s and shows the lion entering the mouth of a cave while Androcles cowers against the wall.
