This is an excellent example of Jean Covens' and Corneille Mortier's 1742 edition of Guillaume Delisle's influential map of western Africa. This map was issued at the height of the Atlantic Slave Trade. It covers the Barbary Coast and the Kingdoms of Fez, Tunis, and Tripoli (Morocco, Algeria, Tunisia, Libya) on the top to the Gulf of Guinea and the Kingdom of Benin (Nigeria, Cameroon) on the bottom and from the Atlantic Ocean on the left to Niger and Chad on the right. The whole offers extensive detail on the tribes and kingdoms of central and west Africa, noting numerous groups based upon both firsthand accounts from explorers, slave and ivory traders, and missionaries, as well as speculative hearsay picked up by these same groups from the African indigini. Of interest is Delisle's curious mapping of the Niger River, which includes a great lake, called Lac de Guarde or Lac de Sigismes formed by the Niger – an embryonic attempt to map the important and unusual Niger Inland Delta. The river, moreover, runs directly eastward rather than correctly to the northeast. Delisle's Niger eventually peters out in the Royaume de Medra rather than correctly turning southwards to rejoin the Atlantic in the Gulf of Guinea. This map also includes the Azores, the Canary Islands, and the Cape Verde Islands.
This map was published by Jean Covens and Corneille Mortier in their 1742 edition of Delisle's Atlas Nouveau in Amsterdam.
The Amsterdam publishing firm of Covens and Mortier (1721 - c. 1862) was the successor to the extensive publishing empire built by Frenchman Pierre Mortier (1661 - 1711). Upon Mortier's death in 1711 his firm was taken over by his son, Cornelius Mortier (1699 - 1783). Cornelius married the sister of Johannes Covens (1697 - 1774) in 1821 and, partnering with his brother in law, established the Covens and Mortier firm. Under the Covens and Mortier imprint, Cornelius and Pierre republished the works of the great 17th and early 18th century Dutch and French cartographers De L'Isle, Allard, Jansson, De Wit, and Ottens among others. They quickly became one of the largest and most prolific Dutch publishing concerns of the 18th century. The firm and its successors published thousands of maps over a 120 year period from 1721 to the mid-1800s. During their long lifespan the Covens and Mortier firm published as Covens and Mortier (1721-1778), J. Covens and Son (1778 - 94) and Mortier, Covens and Son (1794 - c. 1862).
