• 25 8 SIR ABO. [CHAP. As the geographer was a native of Asia Minor, it is only natural that he should pay especial attention to that part of Asia Minor, ^ W0rld, and accordingly we find that he devotes to it three books—the twelfth, thirteenth, and fourteenth. The contents of these are of great value, both because the writer is frequently drawing on his own observation, and also on account of the rich store of information which they provide about the physical geography and products of the country, and the re- ligious and political condition of the people. These points may best be illustrated by a few examples. Strabo notices the absence of trees in Cappadocia, a feature of which he furnishes the explanation when he says that this country, though lying further south than Pontus, is the colder of the two1. He also enlarges on the volcanic activity which at that period still existed about the sides and base of Mount Argaeus in that province, and on the strange craters of the Katakekaumene, or Burnt Country, in Western Phrygia2. He mentions the valuable red earth, which was called ' Sinopic earth/ because it was brought down from the interior to Sinope for export8; and the gum of the storax-tree and the c orris-root/ which were found at Selge in Pisidia*. Observa- tions, also, are frequently introduced on the strange religious worship that prevailed in Asia Minor, with its orgiastic rites, the numerous votaries that were attached to the temples, and the elaborate festival processions8. Finally, the study of political constitutions is illustrated by the descriptions that are given of the federation which was known as the Lycian League8, of the tetrarchies of the Galatae with their elaborate system of govern- ment7, and of the municipal organisation that was established at Ephesus8. The remainder of Asia—that is, in the main, the lands which lie to the southward of the dividing mountain chain—is treated of in the fifteenth and sixteenth books; the former embracing the eastern portion— India, Persia, and the intervening districts; the latter the countries 1 12. 2. 7, io. * n. 2. 7; 13. 4. ii. 8 «* *• io. < 13.7.3. 8 12. a. 3; 12. 3. 31, 3*, 36, 37. « I4. 3. 3. 7 ™* 5- *. 8 14. i. -w.
