Book 2
5.8
It is true that Pytheas of Marseilles affirms that the farthest country north of the British islands is Thule; for which place he says the summer tropic and the arctic circle is all one. But he records no other particulars concerning it; [he does not say] whether Thule is an island, or whether it continues habitable up to the point where the summer tropic becomes one with the arctic circle.The tropic being placed at 24° from the equator by Strabo, and most probably by Pytheas also, the latitude of Thule, according to the observation of this traveller, would be fixed at 66°, which corresponds with the north of Iceland. For myself, I fancy that the northern boundaries of the habitable earth are greatly south of this. Modern writers tell us of nothing beyond Ierne, which lies just north of Britain, where the people live miserably and like savages on account of the severity of the cold. It is here in my opinion the bounds of the habitable earth ought to be fixed.

If on the one hand the parallels of Byzantium and Marseilles are the same, as Hipparchus asserts on the faith of Pytheas, (for heHipparchus. says that at Byzantium the gnomon indicates the same amount of shadow as Pytheas gives for Marseilles,) and at the same time the parallel of the Dnieper is distant from Byzantium about 3800 stadia, it follows, if we take into consideration the distance between Marseilles and Britain, that the circle which passes over the Dnieper traverses Britain as well.Hipparchus placed Marseilles and Byzantium at 30,142 stadia, or 43° 3′ 38″ of latitude, and estimated the parallel for the centre of Britain at 33,942 stadia, or 48° 29′ 19″. Whereas Strabo only allowed for this latter 32,700 stadia, or 46° 42′ 51″. But the truth is that Pytheas, who so frequently misleads people, deceives in this instance too.
