My conquest of Africa is drawn from two French interpreters of Arabic literature, Cardonne (Hist. de l'Afrique et de l'Espagne sous la Domination des Arabes, tom. i. p. 8 - 55) and Otter, (Hist. de l'Academie des Inscriptions, tom. xxi. p. 111 - 125, and 136.) They derive their principal information from Novairi, who composed, A.D. 1331 an Encyclopaedia in more than twenty volumes. The five general parts successively treat of, 1. Physics; 2. Man; 3. Animals; 4. Plants; and, 5. History; and the African affairs are discussed in the vith chapter of the vth section of this last part, (Reiske, Prodidagmata ad Hagji Chalifae Tabulas, p. 232 - 234.) Among the older historians who are quoted by Navairi we may distinguish the original narrative of a soldier who led the van of the Moslems.
