University, University of Michigan, Ann Arbor, MI – 48109, USA; E-mail: ppafil@biol.uoa.gr; pafman@umich.edu Abstract. The development of Herpetology in Greece is examined in this paper. After a brief look at the first reports on amphibians and reptiles from antiquity, a short presentation of their deep impact on classical Greek civilization but also on present day traditions is attempted. The main part of the study is dedicated to the presentation of the major herpetol- ogists that studied Greek herpetofauna during the last two centuries through a division into Schools according to researchers’ origin. Trends in herpetological research and changes in the anthropogeography of herpetologists are also discussed. Last- ly the future tasks of Greek herpetology are presented. Climate, geological history, geographic position and the long human presence in the area are responsible for shaping the particular features of Greek herpetofauna. Around 15% of the Greek herpetofauna comprises endemic species while 16% represent the only European populations in their range.
