the ancient world. "The flow of papyri soon became a torrent," Grenfell recalled. "Merely turning up the soil with one's boot would frequently disclose a layer." The classical author who has most benefited from the finds at Oxyrhynchus is the Athenian playwright Menander (342–291 BC), whose comedies were very popular in Hellenistic times and whose works are frequently found in papyrus fragments. Menander's plays found in fragments at Oxyrhynchus include Misoumenos, Dis Exapaton, Epitrepontes, Karchedonios, Dyskolos and Kolax. The works found at Oxyrhynchus have greatly raised Menander's status among classicists and scholars of Greek theatre. There is an on-line table of contents briefly listing the type of contents of each papyrus or fragment. Since the 1930s, work on the papyri has continued. For many years it was under the supervision of Professor Peter Parsons of Oxford. Eighty large volumes of the Oxyrhynchus Papyri have been published, Since the days of Grenfell and Hunt, the focus of attention at Oxyrhynchus has shifted. Modern archaeologists are interested in learning about the social, economic, and political life of the ancient world. This shift in emphasis had made Oxyrhynchus, if anything, even more important, for the very ordinariness of most of its preserved documents makes them most valuable for modern scholars of social history. Many works on Egyptian and Roman social and economic history and on the history of Christianity rely heavily on documents from Oxyrhynchus. A joint project with Brigham Young University using multi-spectral imaging technology has been extremely successful in recovering previously illegible writing. With multi-spectral imaging, many pictures of the illegible papyrus are taken using different filters, finely tuned to capture certain wavelengths of light. Thus, researchers can find the optimum spectral portion for distinguishing ink from paper in order to display otherwise completely illegible papyri. The amount of text potentially to be deciphered by this technique is huge. A selection of the images obtained during the project and more information on the latest discoveries has been provided on the project's website. On June 21, 2005, the Times Literary Supplement published the text and translation of a newly reconstructed poem by Sappho, together with discussion by Martin L. West. Part of this poem was first published in 1922 from an Oxyrhynchus papyrus, no. 1787 (fragment 1). Most of the rest of the poem has now been found on a papyrus kept at Cologne University. In May 2020, an Egyptian-Spanish archaeological mission
