horizon only the half and the twelfth part of a sign ^note [of the zodiac], and this therefore is the greatest distance of the sun below the horizon at midnight. With us when the sun is at this distance from the horizon before sunrise and after sunset, the atmosphere is enlightened to the east and west respectively. In the winter the sun when at the highest is nine cubits above the horizon. ^note These places, according to Eratosthenes, are distant from Meroe rather more than 23,000 stadia, ^note for he says that [from the parallel of Meroe] to the Hellespont ^note there are 18,000 stadia, and thence to the Dnieper 5000 more. In regions distant 6300 stadia from Byzantium, and north of the Maeotis, the sun during the winter time is, when highest, six cubits [above the horizon]. The longest day consists of seventeen hours. 43

The countries beyond this which border upon the regions uninhabitable on account of their cold, have no interest to the geographer. He who desires to learn about them, and the celestial phenomena which Hipparchus has described, but which we pass over as being too much in detail for our present undertaking, must seek for them in that author. The statements of Posidonius concerning the periscii, the amphiscii, and the heteroscii are likewise too detailed. Still we must touch on these points sufficiently to explain his view, and to point out how far such matters are serviceable in geography, and how far not. The terms made use of refer to the shadows cast from the sun. The sun appears to the senses to describe a circle parallel to that of the earth. ^note Of those people for whom each revolution of the earth produces a day and a night, the sun being carried first over, then under, the earth, some are denominated amphiscii, others heteroscii. The amphiscii are the inhabitants of countries in which when a gnomon is placed perpendicularly on a plane surface, the shadow which it casts at mid-day, falls first to one side then to the other, as the sun illumines first this side, then that. This however only occurs in places situated between the tropics. The heteroscii are those amongst whom the shadow always falls to the north, as with us; or to the
