"This book contains the edition of texts from the archive of Kleon and Theodoros, the engineers who were responsible for the upkeep of the large scale irrigation system in the Fayum during the reigns of Ptolemy II and III between 260 and 237 BC. The Kleon archive is contemporaneous with the famous Zenon archive and offers a window on the same society from a different angle. The edition contains the texts with translation and commentary of 124 Greek papyri, of which 37 are published here for the first time; for the others there are numerous new readings and interpretations. The former edition in the Petrie papyri was over a hundred years old, difficult to consult and in need of revision. In the new edition papyrological studies of the last century are incorporated, and the persons are situated in their historical context, including a royal visit to the province in 253 BC."--Back cover.
