WE will now proceed to examine the statements made by Posidonius in his Treatise on the Ocean. This Treatise contains much geographical information, sometimes given in a manner conformable to the subject, at others too mathematical. It will not, therefore, be amiss to look into some of his statements, both now and afterwards, as opportunity occurs, taking care to confine ourselves within bounds. He deals simply with geography, when he tells us that the earth is spheroidal and the universe too, and admits the necessary consequences of this hypothesis, one of which is, that the earth contains five zones. 2

Posidonius informs us that Parmenides was the first to make this division of the earth into five zones, but that he almost doubled the size of the torrid zone, which is situated between the tropics, by bringing it beyond these into the temperate zones. ^note But according to Aristotle the torrid zone is contained between the tropics, the temperate zones occupying the whole space between the tropics and the arctic circles. ^note Both of these divisions Posidonius justly condemns, for the torrid zone is properly the space rendered uninhabitable by the heat. Whereas more than half of the space between the tropics is inhabited, as we may judge by the Ethiopians who dwell above Egypt. The equator divides the whole of this space into two equal parts.
