Apparently a Teniers the Younger

[Paul Ferguson]

"The recurring motifs in Antwerp-born David Teniers the Younger’s (1610- 1690) representations of alchemists are also found in his numerous highly moralising paintings depicting witches and on the traditional religious theme of The Temptations of St. Anthony. Both subjects are represented with numerous demons. These demons known as grotesques were often represented as possessing different animal parts (Gibson, 2006, pp. 30-33). What connects these subjects with the representation of the alchemist are his signature use of hanging animal specimens which often do not explicitly correlate to an identifiable species and horse skulls."
