Baldung was the first artist to heavily incorporate witches and witchcraft into his artwork (his mentor Albrecht Dürer had sporadically included them but not as prominently as Baldung would). During his lifetime there were few witch trials, therefore, some believe Baldung's depictions of witchcraft to be based on folklore rather than the cultural beliefs of his time. By contrast, throughout the early sixteenth century, humanism became very popular, and within this movement, Latin literature was valorized, particularly poetry and satire, some of which included views on witches that could be combined with witch lore massively accumulated in works such as the Malleus Maleficarum. Baldung partook in this culture, producing not only many works depicting Strasbourg humanists and scenes from ancient art and literature, but what an earlier literature on the artist described as his satirical take on his depiction of witches. Gert von der Osten comments on this aspect of "Baldung his witches humorously, an attitude that reflects the dominant viewpoint of the humanists in Strasbourg at this time who viewed witchcraft as 'lustig,' a matter that was more amusing than serious". However, the separation of a satirical tone from deadly serious vilifying intent proves difficult to maintain for Baldung as it is for many other artists, including his rough contemporary Hieronymus Bosch. Baldung's art simultaneously represents ideals presented in ancient Greek and Roman poetry, such as the pre-16th century notion that witches could control the weather, which Baldung is believed to have alluded to in his 1523 oil painting "Weather Witches", which showcases two attractive and naked witches in front of a stormy sky.
