It was eventually proved to be the latter from which the Nile flowed. Explorers were also active in other parts of the continent. Southern Morocco, the Sahara and the Sudan were traversed in many directions between 1860 and 1875 by Georg Schweinfurth and Gustav Nachtigal. These travellers not only added considerably to geographical knowledge, but obtained invaluable information concerning the people, languages and natural history of the countries in which they sojourned. Among the discoveries
The Book of the Thousand Nights and a Night and appendices have been characterised as “obtrusive, kinky and highly personal”. In 1982, the International Astronomical Union (IAU) began naming features on Saturn's moon Enceladus after characters and places in Burton's translation because “its surface is so strange and mysterious that it was given the "Arabian Nights" as a name bank, linking fantasy landscape with a literary fantasy”.
