Commercially, the 17th century was an age of silver, tobacco and slaves, and Brook shows how the three interconnect to form an intricate economic network. This new international economy is revealed in every aspect of life, not only in the account books of the VOC and the histories of the Jesuit missionaries in China and Latin America, but also in the items depicted in paintings by a Delft artist who died young. All our experience is global. As Brook writes in his final chapter, "If we can see that the history of any one place links us to all places, and ultimately to the history of the entire world, then there is no part of the past -- no holocaust and no achievement -- that is not our collective heritage." Vermeer's Hat shows how this is true of the 17th century and by so doing provides not only valuable historical insight but also enthralling intellectual entertainment.
