The very beginning of Greek theatre started all the way back in 6th century B.C. still even through it was so long ago we still see its effects today in modern dramas. Little is fully known about early Greek theatre because not much information has survived the centuries. Over time new theories and ideas have arisen around the true nature of Greek theatre but there is a solid basic idea of what Greek theatre involved. However what makes it difficult to understand the entirety of Greek theatre is that it was constantly changing and evolving. The size of the chorus, number of actors, structure of performances, costume style – all of these aspects changed over the years.
