Marcus Annaeus Lucanus, De bello civili IX, 411-14: `Libya is the third continent of the world, if one is willing in all things to trust report; but if you judge by the winds and the sky, you will find it to be part of Europe. For the banks of the Nile are not further than the northern Tanais from Gades [Cadiz] in the far west ...'. Lucan trans. J.D. Duff (Loeb, 1943), 534-7.
