The Sasanian Empire was one of the most important periods in ancient Iran and one that experienced flourishingof the Zoroastrian religion. As the official religion in the Sasanian to post-Sasanian period, Zoroastrianism can beunderstood better by studying evidence of the religion’s impact on artifacts such as glassware, coins, silver vessels,pottery, and textiles. This paper shows the importance of “Zoroastrian sacred numbers” on glass fabrication andits impact on a specific type of glassware. Based on his assumption that glassware designs reflect the beliefsof artisans, the author focuses on the number of the facets on the related glassware. To test this hypothesis, theSasanian glassware is compared to other concomitant objects such as royal necklaces and flower petals used inthe Zoroastrian Pahlavi manuscripts. This religion-inspired decorative technique continued into the Early Islamicperiod, during which Shiism strongly preserved the Zoroastrian legacy in glassware.
