In this article, we shall elucidate the use of shadow lengths for regulating prayer times among Zoroastrians, focusing on a part of a Zoroastrian religious book entitled Sh yest N sh yest, written in Middle Persian (Pahlav ) language probably around the 9th c. A.D. Then, we will compare this text with a part of another Persian work entitled Yaw q t al-þUl m wa Dar r al-Nuj m which is written in the second half of the 6th century after Hijra (the 12th c. A.D.) by Ab Muammad al-Najj r in Islamic civilization. For this purpose, we will recalculate the given values for the shadow lengths of the gnomon --taken as the height of a man --in both texts and find the best fitted latitudes for them. Finally, we will mention the similarities of the two texts to investigate the possibility of a historical relationship between them. Moreover, the transmission of this timekeeping method among some civilizations will be discussed.
