Hieronymus Bosch was an Early Netherlandish painter. His work is known for its use of fantastic imagery to illustrate moral and religious concepts and narratives.
Bosch's thematology does not differ much from that of his contemporary artists; the subjects of most of his works are religious: Heaven and Hell, saints, hermits, the Passion of Christ, sin and its punishment. His depictions of evil spirits are nothing more than a product of the Middle Age, visible evidence of the fear of witchcraft and devilry that was so common to people of that era. However, one could say that the style of the individual figures on Bosch' s paintings foretells Realism that was to come a couple of centuries later.
