Mark Janse has spent an entire career being a philhellene. His passion for the Greek language has carried him from the inner workings of the Homeric hexameter to eschatology in Aristophanes, and from diglossia in the Ancient Greek world to clitic doubling in the history of Greek. Among his broad spectrum of interest, two things stand out: one is his enthusiasm for variation and change across time and space in the Hellenic universe; another is his love for the Asia Minor dialects of Cappadocia.

This two-volume book, which is intended as a tribute to Mark from his colleagues, addresses precisely these two topics: the first volume has a broader scope, and addresses different types of varieties in Ancient and Medieval Greek, such as dialects, regiolects and idiolects, also including indepth studies of specific features. The second volume brings together a variety of studies that underline Mark's contribution to Cappadocian and more broadly the Asia Minor Greek dialects. While most contributions focus specifically on Cappadocian, some scholars look into other modern Greek dialects, including Pontic and Cypriot Greek.
