When was the Greek Septuagint's translation begun?

The translation of the Greek Septuagint began in the 3rd century BCE, around 250 BCE, during the reign of Ptolemy II Philadelphus in Alexandria, Egypt. It was initiated to make the Hebrew scriptures accessible to Greek-speaking Jews and eventually became an important text for early Christians. The translation process continued over several decades, resulting in a collection of texts rather than a single, uniform work.
