High Quality Content by WIKIPEDIA articles! The Garden of Earthly Delights is a triptych painted by the early Netherlandish master Hieronymus Bosch (c. 1450–1516), housed in the Museo del Prado in Madrid since 1939. Dating from between 1490 and 1510, when Bosch was about 40 or 50 years old, it is his best-known and most ambitious work. It reveals the artist at the height of his powers; in no other painting does he achieve such complexity of meaning or such vivid imagery.
