The bridge in the village of Blažuj in Ilidža Municipality, near Sarajevo, built in the 16 th century, consists largely of stone spolia from the nearby Roman archaeological site. A stone bearing a relief was built into the parapet, with the relief facing outwards. Though this Roman relief has long been known, it was never the subject of archaeological analysis. This paper determines, from a study of the iconographic content and comparison with other monuments, that it represents the cult of Attis, a Phrygian deity, which reached the province of Dalmatia in the 1 st century. The relief from Blažuj displays most of the typical iconographic features of Attis. These include the crossed legs, the naked belly, the navel, and probably the long curly hair or a Phrygian cap, and a cornucopia or wings. He is leaning on a shepherd's crook, suggesting that the relief is of "Attis tristis." The relief dates from the 2 nd or 3 rd century.
