The 5th book commences with a general sketch of Italy, and refers principally to northern Italy. Dividing its history into ancient and modern, his chief reference for the former is Polybius, and for the latter we are indebted to the observations of the author himself, or to accounts received from others. Still the description of Upper Italy is poor and unsatisfactory, from the author not sufficiently availing himself of Roman resources. Then follows some account of Etruria with its neighbouring islands, Umbria, Samnium, Latium, and Rome, chiefly the result of the author’s own researches and observations. The book concludes with some remarks on the inhabitants of the mountainous districts of Samnium and Campania. The 6th book is a continuation of the same subject. Magna Græcia, Sicily, and the adjacent islands, are noticed, and the author concludes with a short discussion on the extent of the Roman Empire. Descriptions of some places are from his own observations; but the sources whence he takes his other account of Italy and the islands are the works of Polybius, Eratosthenes, Artemidorus, Ephorus, Fabius Pictor, Cæcilius (of Cale Acte in Sicily), and some others, besides an anonymous chorographer, supposed to be a Roman, from the circumstance of his distances being given, not in stadia, but in Roman miles. The 7th book relates, first, to the people north of the Danube,—the Germans, Cimbri, Getæ, Dacians (particularly the European Scythians), and the Crimea; secondly, to the people south of the Danube, viz. those inhabiting Illyricum, Pannonia, Dalmatia, the eastern coast of Thrace to the Euxine, Epirus, Macedonia, Thrace, and the Hellespont. The latter part of this book is not preserved entire in any manuscript, but Kramer has, in his own opinion, succeeded in restoring from the epitomes left to us the greater part of what was wanting. Of Germany, Strabo had tolerable information, but he nowhere states whence it is derived; he may have been partly indebted to Asinius Pollio, whose work he had already examined for the Rhine. For the remaining northern countries, he had Poseidonius and the historians of the Mithridatic war. For the southern countries, he had a lost work of Aristotle on forms of government, Polybius, Poseidonius, and his chief disciples, Theopompus and Ephorus. Incidentally also he quotes Homer and his interpreters, and Philochorus.
