Hieronymus Bosch (1450 - 1516) is a widely celebrated Dutch painter (from the small town s'Hertogenbosch, from which he adopted his surname). His art is considered late Gothic - early Renaissance. Overwhelmingly religious in theme, his works are imaginative, symbolic in nature and often disturbing. Bosch had a truly unique artistic vision.
