The Metrical Unit in Persian and Arabic Poetry

Metricians (or the Arūz specialists) have rightly considered distich as the metrical unit of Arabic poetry. The metricians of Persian poetry following the Arabic Arūz have also considered it as the metrical unit of Persian poetry as well. This has caused some confusion in Persian Arūz or meterology. The confusion lasted forcenturies till the founders of the new Arūz noticed that distich could not be a proper unit of meter for the Persian poetry. They believe that unlike Arabic poetry hemistich is the correct metrical unit in Persian poetry. Besides, some principal differences exist between the metrical units.
