Zenon of Kaunos
Zeno, son of Agreophon, was a native of the Greek town of Kaunos in lower Asia Minor. He moved to the village of Philadelphia on the edge of the Faiyum in Egypt and became a private secretary to Apollonius, the finance minister to Ptolemy II Philadelphus and Ptolemy III Euergetes.
A cache of over 2,000 Greek and Demotic letters and documents written on papyri by Zeno were discovered in the 1900s and are referred to as the Zenon Archive or Zenon Papyri.
A substantial part of the Zenon Papyri are now online and grammatically tagged at the Perseus Project hosted at Tufts University.
Drimylus and Dionysius, two Greek employees under Zeno, were known for their involvement in selling women as sex-slaves in the areas that Zeno was visiting.
