Passage: The focus of the project is now mainly on the publication of this vast archive of material: by 2003 4,700 items had been translated, edited and published. Publication continues at the rate of about one new volume each year. Each volume contains a selection of material, covering a wide range of subjects. The editors include senior professionals but also students studying papyrology at the doctoral or undergraduate level. Thus recent volumes offer early fragments of the Gospels and of the Book of Revelation, early witnesses to the texts of Apollonius Rhodius, Aristophanes, Demosthenes, and Euripides, previously unknown texts of Simonides and Menander and of the epigrammatist Nicarchus. Other subjects covered include specimens of Greek music and documents relating to magic and astrology.
