Letter of Aristeas and the Pithom Stele

In the mid-3rd century BC, King Ptolemy II Philadelphus of Egypt ordered a translation of the ancient Hebrew scriptures for the Library of Alexandria, which resulted in the creation of the Septuagint. The Letter of Aristeas, also called the Letter to Philocrates, was written by someone who claimed to have been part of the events that created the original translation of the Septuagint. It was treated as an authentic historical document by ancient Jewish historians, such as Aristobulus of Alexandria circa 150 BC, Philo of Alexandria circa 15 AD, and Josephus circa 93 AD. As Aristobulus quoted the Letter around 150 BC, the letter clearly predates Aristobulus by enough time for him to see it as an authentic document, which would imply prior to 200 BC.
Since the time of Jerome, circa 400 BC, the Letter's authenticity has been debated. It was generally considered authentic until the 1500s when Jerome's views were repeated by the Spanish humanist Luis Vives. The Letter came under attack throughout the 1600s through the 1800s, and by the 1900s was viewed as a fictional document. Most of the arguments levied against it, were based on a lack of understanding of who Ptolemy II Philadelphus was, and why he would be depicted as worshiping the Jewish god. Latin critics did not understand the references to Plato's Cratylus and translated Δία as Dis (Jupiter), which would force the origin of the Letter to a later date after Rome had risen in power. In the time period this Letter is set, Carthage sill dominated the Western Mediterranean and Romans only ruled Italy. The reference to Δία was, in fact, part of a reference to Ζῆνα and Δία found in Plato's Cratylus, which was a reference to the Greek folktales about Zeus being the creator of life. References to the creator god in the letter were traditionally dismissed as being unlikely, as a Greek king would not have worshiped the Jewish god, however, this argument was based on a lack of understanding of Philadelphus. The Pithom Stele, found in the late 1800s shows that Philadelphus embedded himself in the Egyptian religions, portraying himself as the son of Atum, the creator god of ancient Egypt.
The Pithom Stele was discovered at Tell el-Maskhuta, Egypt. It had originally been erected in the Temple of Atum at Pithom (Tell el-Maskhuta), circa 264 BC. The city of Pithom appears to have been moved at least once. Pharaoh Necho II seems to have founded a city of Pithom at the site of El Retaba eight miles west of Tell el-Maskhuta, circa 600 BC, when the Canal of the Pharaohs was dug linking the Nile to the Gulf of Suez. This canal was filled with sand and debris repeatedly and then cleared repeatedly. The Greek historian Herodotus, circa 430 BC claimed it was opened on the orders of the Persian King Darius, circa 490 BC. The Greek philosopher Aristotle, circa 330 BC, claimed the canal was never completed, meaning it was not open during his lifetime. It is generally accepted today that Ptolemy II Philadelphus reopened the canal during his lifetime, and built Heroöpolis, which was called Per-Atum (Pithom), including the Temple of Atum where the Pithom Stele was found.
