Naos of the Decades
From Wikipedia, the free encyclopedia

Naos of the Decades, also known as the Saft el-Hinna Naos, is a black granite naos preserved in several parts that have been discovered almost two centuries apart.
The naos is dedicated to the god Shu-Sopdu and dates to the reign of Nectanebo I. An astrological calendar is engraved on its sides depicting 36 decades, or 10-day periods marked by small constellations of stars called decans.[1]
