Little is known of Hieronymus Bosch’s life or training. Bosch left behind no letters or diaries, and what has been identified has been taken from brief references to him in the municipal records and in the account books of the local order of the Brotherhood of Our Lady. Nothing is known of his personality or his thoughts on the meaning of his art. Bosch’s date of birth has not been determined with certainty. It is estimated at c. 1450 on the basis of a hand drawn portrait (which may be a self-portrait) made shortly before his death in 1516. The drawing shows the artist at an advanced age, probably in his late sixties
Carl Gustav Jung has him pegged as the master of the monstrous, the discoverer of the unconscious.
This is only a part of the painting and depicts the earthly delights with numerous nude figures and tremendous fruit and birds on the middle panel which most people think was depicting the Garden of Eden. God creating the earth is on another panel on the left and hell with depictions of fantastic punishments of the various types of sinners on the right panel.
Although there is no proof, it has been thought that Bosch was a member of the Brethren of the Free Spirit, a heretical group which flourished throughout Europe for several hundred years after their first appearance in the thirteenth century. Little is known about this sect, but it is supposed that they practiced sexual promiscuity as part of their religious rites, through which they attempted to achieve the state of innocence possessed by Adam before the Fall; hence they are also called Adamites.
Looking at some of the pictures makes one wonder.
Most people say this is nothing but a wondrous and strange fantasy. For a view of most of his painting have a good look and make up your own mind.
