Letter of Zenon dealing with the affairs of Palestine. One of the most valuable sources of information about conditions in Palestine in the middle of the third century is the correspondence of Zenon, an official of the finance minister Apollonius who served under Ptolemy II. Zenon’s archives were found in the Fayoum, Egypt, in 1915, where he retired after the completion of his service. Several of his letters deal with his travels and business in Palestine.
