The Letter of Aristeas and the Septuagint: Royal Patronage, Alexandria's Library, and the Seventy-Two Translators

The Legend of the Seventy-Two: Summary of the Narrative

The Letter of Aristeas (Epistole Aristeou) is an ancient Hellenistic Jewish pseudepigraphal document composed in literary Greek, purporting to be an eyewitness letter written by a pagan Greek courtier named Aristeas to his brother Philocrates during the reign of Pharaoh Ptolemy II Philadelphus (285–246 BC).

According to the letter, Demetrius of Phalerum, the chief librarian of the royal Library of Alexandria, approached King Ptolemy with an urgent intellectual deficit:

[THE ROYAL ROYAL DECREE FOR A WORLD-CLASS LIBRARY (LETTER OF ARISTEAS 9–11)]
"When Demetrius of Phalerum was placed in charge of the king's library,
 he received large sums of money in order to collect, if possible, all the books
 in the world... He informed the king: 'Information has reached me that the laws
 of the Jews are also worthy of transcription and inclusion in your library.'
 The king replied: 'What is there to prevent you from doing this?
 All necessary resources are placed at your disposal.'"

To secure the Hebrew Torah, King Ptolemy released over 100,000 Jewish slaves in Egypt at his own expense and sent lavish golden gifts to the High Priest Eleazar in Jerusalem.

In return, Eleazar dispatched 72 elder scholars—six from each of the twelve tribes of Israel—bearing master scrolls written in letters of gold on fine parchment.

The translators were housed in a serene retreat on the island of Pharos (connected by a causeway to the mainland). Working collaboratively, they completed the translation of the Pentateuch into Greek in exactly 72 days. When the translation was read before the Jewish community of Alexandria, it was declared so perfect and divinely inspired that a solemn curse was uttered against anyone who would ever alter, add to, or delete a single word.

This foundational narrative gave rise to the historic designation of the Greek translation: The Septuagint (from the Latin septuaginta, meaning "Seventy", abbreviated LXX).

Historical Realities vs. Hellenistic Apologetic Propaganda

Modern textual criticism and historical analysis have established that the Letter of Aristeas is not an authentic 3rd-century BC dispatch by a pagan royal official, but a brilliant piece of Jewish apologetic literature composed around 150–100 BC by an educated Alexandrian Jew.

Critical historical discrepancies include:

1. Demetrius of Phalerum's Exile: Historical records from Hermippus of Smyrna confirm that when Ptolemy II Philadelphus took power in 285 BC, he immediately banished Demetrius to Upper Egypt, where he died of a snakebite. Demetrius could not have supervised the project under Philadelphus.
2. Pseudonymous Pagan Voice: The author adopts a pagan persona to validate Jewish culture in the eyes of the Greco-Roman world. The pagan king repeatedly praises the wisdom, philosophy, and moral legislation of the Jews, presenting Mosaic law as the supreme philosophical constitution on earth.
3. Linguistic Uniformity: The Greek of the Letter of Aristeas is the high literary koine of late 2nd-century BC Alexandria, vastly different from the vernacular translation Greek found in the Septuagint itself.

Demetrius of Phalerum and the Great Library of Alexandria

While the dramatic narrative is embellished, the historical core reflects a monumental truth: The translation of the Hebrew Scriptures into Greek took place in Alexandria, Egypt, during the 3rd century BC.

Alexandria was the intellectual capital of the Hellenistic world. Under the Ptolemaic dynasty, Greek had become the lingua franca of commerce, administration, and philosophy. Within two generations, the massive Jewish diaspora living in Alexandria could no longer speak or read biblical Hebrew.

The true impetus for the Septuagint was twofold:

• Internal Liturgical Necessity: Alexandrian synagogues desperately needed the Torah in Greek so that community members could understand the weekly Scripture readings.
• Ptolemaic Imperial Library Ambitions: The Ptolemies sought to compile a universal repository of human knowledge. Translating the foundational law code of an influential ethnic population residing in Egypt aligned perfectly with Ptolemaic imperial policy.

The Miracle of Seventy-Two Identical Translations: Myth or Fact?

The original Letter of Aristeas does not claim that the 72 translators worked in isolated cells and miraculously produced identical texts word-for-word.

Aristeas describes a collaborative editorial committee: "They accomplished their work through mutual consultation, harmonizing their different interpretations, and the result of this agreement was transcribed by Demetrius" (Letter of Aristeas 302).

The legend of the miraculous isolated cells developed centuries later among early Christian apologists:

• Philo of Alexandria (c. 40 AD): Claimed that the translators worked separately and were divinely inspired, writing "as though dictated by an invisible prompter, the very same words."
• Justin Martyr (c. 150 AD) & Irenaeus (c. 180 AD): Popularized the story across the Christian world, claiming Ptolemy shut each translator into a separate chamber, and when their scrolls were compared, they were identical in every letter.

Textual evidence demonstrates that only the Pentateuch (Genesis to Deuteronomy) was translated in the 3rd century BC. The remaining books (the Prophets and the Writings) were translated gradually over the following two centuries by different translators displaying vastly different translation styles and vocabularies.

Scope of Translation	The entire Jewish Law (sometimes mistaken for whole Bible)	Only the Pentateuch (Torah) was translated at this initial stage
Primary Motivation	Royal initiative by the pagan King for the Library of Alexandria	Internal need of Greek-speaking Jewish diaspora synagogues

Three-Tier Evidentiary Evaluation: The Letter of Aristeas

Tier 1: Material and Physical Archaeology

• Manuscript Transmission: Preserved in over twenty Byzantine Greek manuscripts (such as Codex Parisinus Graecus 128) and cited extensively by Flavius Josephus (Antiquities of the Jews XII.2).
• Archaeological Sites: The Island of Pharos and the foundations of the Ptolemaic harbor works excavated by modern maritime archaeologists corroborate the geographical setting described in the text.

Tier 2: Textual and Internal Epigraphy

• Ptolemaic Court Titles: The letter accurately employs genuine 2nd-century BC Ptolemaic administrative terminology, court titles (archisomatophylax, diadokhoi), and monetary values, reflecting intimate familiarity with the royal Alexandrian court.
• Epigraphical Parallels: Inscriptions discovered at the sanctuary of Didyma and papyri from the Zenon Archive (mid-3rd century BC) verify the administrative procedures of the early Ptolemaic bureaucracy.

Tier 3: Theological and Canonical Transmission

• Historical Monument: Provides the primary literary bridge explaining how the Hebrew Scriptures became the Greek Bible utilized by the Apostles, the New Testament authors, and the early Christian Church.
• Canonical Boundary: Classified uniformly as Hellenistic Jewish pseudepigrapha; valued as an invaluable historical source on the origins of the Septuagint, but never included in any biblical canon.

Frequently Asked Questions

Why is the Septuagint so critical for the New Testament?

Over 80% of the Old Testament quotations found in the New Testament are taken directly from the Septuagint rather than the Hebrew Masoretic text. The early Gentile Christian Church spread throughout the Roman Empire using the Septuagint as their authoritative Bible.

Did the translators really write in letters of gold?

While the Letter of Aristeas mentions scrolls written with gold ink (chrysographia), this was a recognized luxury scribal practice in Hellenistic royal courts. Jewish rabbinic halakhah later specifically forbade writing the Divine Name in gold on kosher liturgical Torah scrolls (Tractate Soferim 1:9).

How did the Letter of Aristeas impact Christian views of the Bible?

Early Christians viewed the story of the 72 translators as historical proof that the Septuagint was directly inspired by the Holy Spirit. This allowed early Church Fathers to defend Septuagintal readings—such as the Greek word parthenos ("virgin") in Isaiah 7:14—as divinely ordained.
