Philip Hook takes the lid off the world of art dealing to reveal the brilliance, cunning, greed and daring of its practitioners. In a richly anecdotal narrative he describes the rise and occasional fall of the extraordinary men and women who over the centuries have made it their business to sell art to kings, merchants, nobles, entrepreneurs and museums.From its beginnings in Antwerp, where paintings were sometimes sold by weight, to the rich hauteur of the contemporary gallery in London, Paris and New York, art dealing has been about identifying what is intangible but infinitely desirable, and then finding clients for whom it is irresistible.
