Long ago, on islands in the Aegean sea, people spoke a language akin to what we call Greek. First the Minoans, then the Melesians, then the Ionians and Dorians passed this language down or were assimilated into it. In the Pelopenesian Wars, Athens may have ultimately lost, but Attic Greek prevailed as the primary dialect, almost solely because of one man, Alexander the Great. When he conquered the known world, he carried Greek and Hellenistic culture from Italy to India. Greek continued as the lingua franca of the Roman Empire well into the fourth century. Soon, however, Greek's worldwide domination was reduced to the Byzantine Empire and ultimately just Greece. Most importantly, though, all the remaining parts of Holy Scripture after the Old Testament were written in Koine, that is "Common", Greek.
