The work includes Strabo's geographical treatise, in the version of the text already printed "in aedibus Aldi et Andreae soceri" in 1516. For the printing in question, the text transcribed and translated by Guarino da Verona and Gregorio Trifernate was corrected, as the scholar Graesse informs, by M. Hopper, with the help of C. Heresbach, H. Gemusaeus, H. Glareanus and J. Hartung. The dedicatory letter, dated in Basel on 26 August 1549, is followed by an extensive thematic index. The Greek historian and geographer Strabo, who arrived in Rome in about 45 AD, was a student of the Peripatetic philosopher Xenarchus and the grammarian Tyrannion. His vast geographical treatise in 17 books, of which the seventh has survived incomplete, is a fundamental text for understanding the territories, history, uses and customs of the ancient world; In composing the work, Strabo consulted numerous sources, providing us with a wealth of erudite information on the lands then known.
