The country deep in the interior, and above the Syrtis and Cyrenæa, a very sterile and dry tract, is in the possession of Libyans. First are the Nasamones, then Psylli, and some Gætuli, then Garamantes; somewhat more towards the east (than the Nasamones) are the Marmaridæ, who are situated for the most part on the boundaries of Cyrenæa, and extend to the temple of Ammon. It is asserted, that persons directing their course from the recess of the Great Syrtis, (namely,) from about the neighbourhood of Automala,1021 in the direction of the winter sunrise, arrive on the fourth day at Augila.1022 This place resembles Ammon, and is productive of palm trees, and is well supplied with water. It is situated beyond Cyrenæa to the south: for 100 stadia the soil produces trees; for another 100 stadia the land is only sown, but from excessive heat does not grow rice.

Above these parts is the district which produces silphium, then follows the uninhabited tract, and the country of the Garamantes. The district which produces silphium is narrow, long, and dry, extending in an easterly direction about 1000 stadia, but in breadth 300 stadia, or rather more, at least as far as has been ascertained. For we may conjecture that all countries which lie on the same parallel (of latitude) have the same climate, and produce the same plants; but since many deserts intervene, we cannot know every place. In like manner, we have no information respecting the country beyond (the temple of) Ammon, nor of the oases, as far as Ethiopia, nor can we state distinctly what are the boundaries of Ethiopia, nor of Africa, nor even of the country close upon Egypt, still less of the parts bordering on the ocean.
