Strabo's Geography was not well known in ancient and medieval times. It was never the subject of literary or scientific study. There was no need to write commentaries on it as on the poets, orators, and philosophers. Nevertheless the medieval manuscripts of Strabo do contain meagre scholia, and for one reason or another some of them are valuable. Moreover as a whole they throw light on the history of Greek scholarship in an important but obscure period. It seems desirable therefore to edit them entire, to examine their relationships, and point out their significance.
