The 12th book commences with a detailed account of Anatolia, and contains the northern part. It was to have been expected that Strabo would have described most of these countries as an eye-witness, lying, as they do, so near his native country, Cappadocia. But this expectation vanishes, when we discover the meagreness of his account. With the exception of Pontus and Cappadocia, he had seen little of the rest, and depends upon historians and oral information. For earlier times, his authorities are Herodotus, Hellanicus, Theopompus, Ephorus, Artemidorus, Apollodorus, and Demetrius of Skepsis; for later times, historians of the wars of Mithridates and Pompey. For the ancient history of the Mysians and Phrygians, he is indebted to the celebrated Lydian historian Xanthus, and Menecrates. The 13th book continues the description of Anatolia. The greater part of the book is occupied with a dissertation on the Troad. Strabo had travelled over the country himself, but his great authority is Homer and Demetrius of Skepsis, the author of a work in twenty-six books, containing an historical and geographical commentary on that part of the second book of the Iliad, in which the forces of the Trojans are enumerated. A learned digression on the Leleges, Cilices, and Pelasgi, who preceded the Æolians and Ionians in the occupation of the country, is principally taken from Menecrates and Demetrius of Skepsis. The description then turns to the interior, and the account of the Æolian cities is probably due to Poseidonius. Throughout this book are evidences of great care and desire for accuracy. The 14th book continues with the remainder of Anatolia, and an account of the islands Samos, Chios, Rhodes, and Cyprus. The authorities followed are, on the whole, the same as in the previous book—Herodotus, Thucydides, Ephorus, Artemidorus, Eratosthenes, and Poseidonius; besides Pherecydes of Syros, who wrote on the Ionian migration, and Anaximenes of Lampsacus, the author of a history in Greek of the Milesian colonies. For Caria, he had the historians of Alexander and an author named Philip, who wrote on the Leleges and Carians. For Cyprus he had Damastes and Eratosthenes.
