Dieppe maps
The Dieppe maps are a series of world maps and atlases produced in Dieppe, France, in the 1540s, 1550s, and 1560s. They are large hand-produced works, commissioned for wealthy and royal patrons, including Kings Henry II of France and Henry VIII of England. The Dieppe school of cartographers included Pierre Desceliers, Jean Rotz, Guillaume Le Testu, Guillaume Brouscon and Nicolas Desliens.
The Dieppe Maps known to have existed into modern times include the following:
Sarah Toulouse has published a more detailed and comprehensive list of 37 charts and atlases made between 1542 and 1635 and belonging to the Dieppe or Norman school of marine cartography.
Because many of the inscriptions on the Dieppe maps are written in French, Portuguese or Gallicised Portuguese, it has often been assumed that the Dieppe school of mapmakers were working from Portuguese sources that no longer exist. It has been assumed that Portuguese cartographers were bribed for information of the latest discoveries, despite the official Portuguese ‘Politica de sigilo’ (‘policy of silence’). The Cantino map of 1502 (not a Dieppe school map) shows evidence of second-hand Portuguese sources, and this has been taken by some as supporting evidence for this assumption.
Common features of most of the Dieppe world maps (see Vallard 1547, Desceliers 1550) are the compass roses and navigational rhumb lines, suggestive of a sea-chart. However, the maps are best understood as works of art, clearly intended to be spread out on a table, and containing information on the latest discoveries, side by side with mythological references and illustrations. For example, the Desceliers 1550 map carries descriptions of early French attempts to colonise Canada, the conquests of Peru by the Spanish and the Portuguese sea-trade among the Spice Islands. On the same map can be found descriptions of legendary Cathay, king Prester John in Ethiopia, and the race of Amazons in Russia. Other Dieppe maps also carry fictitious features such as the Marco Polo inspired Zanzibar/Îles des Geanz. (see Vallard 1547, Rotz 1542 and Dauphin c. 1536–42). As with other maps made before the 17th century, the Dieppe maps show no knowledge of longitude. While latitude could be marked in degrees as observed by astrolabe or quadrant, easting could only be given in distance. Mercator's projection first appeared in 1568–9, a development too late to influence the Dieppe cartographers.
Most of the Dieppe maps depict a large land mass entitled Jave la Grande or terre de lucac (Locach) between what is now Indonesia and Antarctica. In the English-speaking world particularly, academic and popular interest in the Dieppe maps over the last 150 years has focused largely on this feature of the maps. This is because Jave la Grande is thought by some writers to provide clues of a possible Portuguese exploration of Australia's coasts in the 1520s. However, the most recent academic writings on the Dieppe maps by Carile (1997), Brunelle (2007) and King (2009) have suggested that the maps need to be considered in their entirety, and consideration needs to be given to what they reveal about various influences on the mapmakers, as well as French aspirations.
This group of writers argue that the maps are not necessarily literal records of voyages of exploration. On the 1543 world chart of Guillaume Brouscon this feature, the northern part of TERRE OSTRALE (Terra Australis), is called terre de lucac (Locach); on this chart, la Jave grande refers to Java, and Jave refers to an island to its east (Bali, Lombok or Sumbawa). Similarly, on the 1570 Carte cosmographique ou Universelle description du monde of Jean Cossin, an originator of the sinusoidal projection, this feature is called Terre de lucac, as it is also by Jacques de Vaulx on his chart. On the so-called Pasterot atlas (British Library MS Egerton 1513) it is called IOCAT, another form of Locach.
It is noteworthy that the Unfortunate Isles (Islas Infortunadas) discovered during Magellan's voyage across the Pacific in 1522 appear on the Dieppe maps, renamed with a corrupted version of his name as ysles de magna and ye de saill or some slight variation thereof, and displaced to the vicinity of Jave la Grande / Lucach.
