are in the macaronic poems of Jalal ad-Din Muhammad Rumi (1207–1273), who lived in Iconium (Konya), and some ghazals by his son Sultan Walad. Interpretation of the Greek language texts is difficult as they are written in Arabic script, and in Rumi's case without vowel points; Dedes' edition (Δέδες) is the most recent edition. By the early 20th century many Cappadocians had shifted to Turkish altogether (written with the Greek alphabet, Karamanlidika). Where Greek was maintained (numerous villages near Kayseri, including Misthi, Malakopea, Prokopion, Karvali, and Anakou), it became heavily influenced by the surrounding Turkish. However, there are next to no written documents in Medieval or early Modern Cappadocian, as the language was, and still essentially is, a spoken language only. Those educated to read and write, such as priests, would do so in the more classicising literary Greek. The earliest outside studies of spoken Cappadocian date from the 19th century, but are generally not very accurate. One of the first documented studies was Modern Greek in Asia Minor: A study of dialect of Silly, Cappadocia and Pharasa (Cambridge: Cambridge University Press, 1916), by Richard MacGillivray Dawkins (1871–1955), then a fellow of Emmanuel College, Cambridge and later the first Bywater and Sotheby Professor of Byzantine and Modern Greek Language and Literature at the University of Oxford, based on fieldwork conducted by the author in Cappadocia in 1909–1911. After the population exchange, several Cappadocian dialects have been described by collaborators of the Center for Asia Minor Studies (Κέντρον Μικρασιατικών Σπουδών) in Athens: Uluağaç (I.I. Kesisoglou, 1951), Aravan (D. Phosteris & I.I. Kesisoglou, 1960), Axo (G. Mavrochalyvidis & I.I. Kesisoglou, 1960) and Anaku (A.P. Costakis, 1964), resulting in a series of grammars. In recent years, the study of Cappadocian has seen a revival following the pioneering work on Language Contact, Creolization, and Genetic Linguistics (Berkeley: University of California Press, 1988) by Sarah Grey Thomason and Terrence Kaufman, and a series of publications on various aspects of Cappadocian linguistics by Mark Janse, professor at Roosevelt Academy, who has also contributed a grammatical survey of Cappadocian to a forthcoming handbook on Modern Greek dialects edited by Christos Tzitzilis (Aristotle University of Thessaloniki). The recent discovery of Cappadocian speakers by Janse and Papazachariou will result in the release of a new dictionary and a compilation of texts. Cappadocian Greek is well known from the linguistic literature as being one of the first well documented cases
