Arabic background in a movie depicting Greece's Archaic period?
Throughout this 3-hour long movie, I heard Classical Arabic language spoken in the background and sometimes Moroccan Arabic. I also noticed that some of the music played during the feast celebrations in Penelope's house was of Berber Moroccan origin including the Rhaita flutes.
The Question is:
Why did the director choose to include Arabic in a movie depicting a city in Greece (Ελλάδα) during its Archaic period if not even earlier times since Homer (author of The Odyssey) existed before 800 BC (or 1200 BC - disputed) while Classic Arabic started to be spoken around 4th century AD and old North Arabic started around 6th century BC in the Arabia region.
Can someone help me?
