The mausoleum Chashma Ayub reflects the dynamics of Central Asian architecture. First as a mutual succession of religious values, representing the cult of Ayub and his story that is known in early Christian and Jewish sources as Jove (Job). Second, it was a representative type of mausoleum and architectural decorative art of the period from the reign of the Karakhanids in the 11^thcentury until the middle of the 15^thcentury. At that time, it was a unique form of mausoleum and no other khazira had such a portal. The significant original décor of carved monochrome terracotta tinted with golden ocher is very unique for pre-Mongolian times (the 12^th-13^th centuries). The accents of turquoise glaze are one of the first examples of employment of color and mark. It reflects an important step in the ceramics technology that, in later times, became prevalent along the entire Silk Roads corridor.
