 Similarly, James Bruce in 1835 published "Travels through part of Africa, Syria, Egypt, and Arabia".On the other hand, as early as 1670 John Ogilby under the title "Africa" published ""an accurate Description of the Regions of Egypt, Barbary, Libya, and Billedulgerid, the Land of Negroes, Guinea, Æthiopia, and the Abyssines, with all the adjacent Islands, either in the Mediterranean, Atlantic, Southern, or Oriental Seas, belonging thereunto"".The usual line taken to divide Africa from Asia today is at the Isthmus of Suez, the narrowest gap between the Mediterranean and Gulf of Suez, the route today followed by the Suez Canal.
