This is an edition with introduction and detailed commentary of the Oxyrhynchus Glossary, a lexicon preserved in several papyrus fragments with glosses taken from Greek, Greek dialects and 'foreign languages', especially Near-Eastern languages. In the entries many historians, periegetes, mythographers of Hellenistic time are quoted. The Oxyrhynchus Glossary is a unique document for the history of Greek lexicography as well as for the study of the relationship between Greek and non-Greek languages and the problems related to linguistic exchanges in the Near Eastern areas.
