Remarkably, this is the most detailed map of Vietnam in Joan Blaeu’s famous Atlas maior of the 1660’s. The map appeared in earlier Blaeu-atlases from 1634 onwards. The map is dedicated to Laurens Reael, governor-general of the VOC from 1616 to 1619 and at the time that the map was published one of the directors of the Amsterdam chamber of the company. The dedication with his coat-of-arms is depicted in the lower left corner of the map. The map covers Asia from India to Japan and the Australian north coasts. Indochina is in the top of the map.
