"New map of the costs of Holland, Zeeland, Flanders, Picardy, & Normandy, from the Brille, to Dieppe, with part of the costs of England, from the mouth of the Thames, and the neighbouring isles to Bevesier, where we see all the seaports, sandbanks & rocks, for the use of the armies of his British Majesty". Amsterdam P. Mortar 1693 Gr. 59 x 94,5 cm assembled from 2 pl. hand-coloured. Framed. Chart of British origin designed and etched by Romein de Hooghe who was at that time in the service of King William III of England. With 2 inset views of Calais and Dunkirk. From Pierre Mortier's "Cartes marines à l'usage du Roy de la Grande Bretagne" that was the most expensive sea-atlas published in 17th-c. Amsterdam. Contrary to Mortier's counterfeited "Neptune François", published jointly with H. Jaillot, this work was not based on a printed French prototype, but on ms. charts. The magnificient work was intended as a showpiece rather than as something being used by pilots at sea. Ref. Koeman IV, M. Mor 5/1.
