Ptolemy II Philadelphus
The construction of the settlement of "Philadelphia" under Ptolemy II Philadelphus was recorded in detail by a 3rd-century BC Greek public official named Zeno (or Zenon, ). Zeno, a native of Kaunos in lower Asia Minor, came to Faiyum to work as private secretary to Apollonius, the finance minister to Ptolemy II Philadelphus (and later to Ptolemy III Euergetes). During his employment, Zeno wrote detailed descriptions of the construction of theatres, gymnasiums, palaces and baths in the 250s and 240s BC, as well as making copious written records of various legal and financial transactions between citizens.
