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.
