Read this: One of the first recorded instances of translation in the West was the rendering of the Old Testament into Greek in the 3rd century BCE. The translation is known as the "Septuagint", a name that refers to the seventy translators (seventy-two, in some versions) who were commissioned to translate the Bible at Alexandria, Egypt. Each translator worked in solitary confinement in his own cell, and according to legend all seventy versions proved identical. The Septuagint became the source text for later translations into many languages, including Latin, Coptic, Armenian and Georgian.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): When was the Old Testament translated into Greek?
