I think it actually can be E53, because Hormoz Farhat, “The Dastgah Concept of Persian Music”, p. 12, mentions Aby-Nasr Farabi (10th century) and gives a 17-tone system of Ormavi using Pythagoreans minor seconds (limmas) and commas, and also says that the “comma is close to an eighth of a tone”. Farhat says that the scale of Ormavi has the following intervals, L = limma = minor second, C = comma: L, L, C - L, L, C - L + L, L, C - L, L, C - L + L, L, C He does not explain how to read this list, but I gather that C - L + L means th intervals C, C - L, C + L form the preceding comma in the list.
