The ionic metre was particularly associated with Persia; for example, the opening chorus of Aeschylus's Persians was in this metre. The metre re-emerges in Persian poetry of the 10th century and later. The author of The Persian Metres, L. P. Elwell-Sutton, conjectured that there may have been a continuous tradition of this rhythm in Persian music from ancient times; although evidence for this is lacking.Thiesen, Finn (1982).
