I thought this was interesting, from the introduction of Five Modern No Plays by Yukio Mishima (transl. Donald Keene)

“In some respects Nō suggests ancient Greek drama: there are few characters; there is a chorus, dances, and masks (worn by the principal dancer in many cases), and an abundant use of traditional or legendary themes. How-ever, unlike Greek drama, which became increasingly realistic, Nō developed into an essentially symbolic theatre, where both the texts of the plays and the gestures of the actors were intended to suggest unspoken, indefinable realities.”
