The excavations were sponsored by the Graeco-Roman branch and thus were concerned with recovering papyri from the Graeco-Roman period rather than objects or material from different time periods.
The extensive Ptolemaic cemetery contained large amounts of Greek and demotic papyri from the 3rd cenntury BCE which was well preserved.
