Description of Africa was taken largely from the firsthand geographical work Cosmographia et geographia de Affrica completed by Leo Africanus in 1526 and published under the title Della descrittione dell’Africa et delle cose notabili che ivi sono by Giovanni Battista Ramusio in his collection of travellers' accounts Delle navigationi e viaggi in Venice in 1550. It contained the first detailed descriptions published in Europe of the Barbary Coast and the gold-trading kingdoms of west-central Africa. The book was dictated in Italian by Leo Africanus, the famed Moorish traveler and merchant who had been captured by pirates and sold as a slave. Presented, along with his book, to Pope Leo X, he was baptized and freed. Leo, whose name he took in baptism, suggested that he recast his Arabic work in Italian; it was completed in 1526. It was republished repeatedly by Ramusio in his Delle navigationi e viaggi, translated into French and into Latin for the erudite, both in 1556.
