Polis-Pyrgos Archaeological Project I The material presented here is derived from an extensive survey conducted by the Polis-Pyrgos Archaeological Project (PAP) in 1992-1994, 1996-1997, and 1999 in the area between the western bank of the Chrysochou River and Kato Pyrgos in northwestern Cyprus. This is the first comprehensive publication of ceramics and ground stone artefacts from the neighbouring area of Polis tis Chrysochous (Polis), formerly ancient Marion and Arsinoe. The pottery constitutes the bulk of the material. Because of the number of artefacts the material will be presented in two volumes. The main task of each contribution is to present the artefacts recorded in its local, regional and whole island context, as far as possible. The second volume will contain post-prehistoric ceramics, Chalcolithic to Iron Age ground stone artefacts, as well as contribution on the environment and resources.
