A series of Syriac inscriptions dating to the 2nd and 3rd centuries CE have been found at the site.[4] Inscriptions that refer to the "Lord of the gods," are thought to be references to Sin.[5] In nearby Edessa, worship of Sin, who was also the main deity in Harran, extended back to the beginning of the 1st millennium BCE, and continued until some time in the 4th century CE when solar worship began to predominate.[5]
