Jason's quest for the Golden Fleece required him to bypass a fearsome dragon, which he was able to do with a sleeping potion given to him by the witch Medea. Rosa selected classical narratives to prove he was a great and learned painter of histories, and he showcased the novelty of being among the first 16th- or 17th-century artists to portray this particular story. Rosa turned the ancient epic into a moody struggle by transmitting the mystery and magic of his earlier witchcraft imagery. Utilizing the energetic and spontaneous qualities of his draftsmanship, the violence of Jason's feat is emphasized by a claustrophobic and savage environment of crags and "blasted" trees that frames the dynamic diagonals of the hero and recoiling dragon.
