Map of the Elbe River. 17th-century illustrated map of part of the Elbe River near Hamburg, Germany. Hamburg is shown at upper centre. The Elbe River flows for over 1000 kilometres from its source to its mouth in the North Sea near Hamburg. This map is illustrated with coats-of-arms and pictures of cities, ships, hills, islands and other geographical features. The text annotations and inscriptions are in Latin. This map is from 'Le theatre du monde' or 'Novvel atlas' (Amsterdam, 1647) by Dutch map-makers Willem Janszoon Blaeu (1571-1638) and Joan Blaeu (1596-1673).
