The early Odrysian elite in archaeology

Archaeological evidence confirms that by the middle of the 5th century BC, a new and powerful elite had emerged that accumulated a wealth of precious artifacts of both local and regional origin. Burial practices were changing after the Persian withdrawal and a new type of elite burial emerged in central Thrace in the form of tombs with ashlar masonry, sometimes with stone sarcophagi. The tomb of Rouets from the late 5th century even contained traces of wall paintings. The earliest of these new elite tombs can be found in the necropolis of Duvanli, with the oldest tombs dating to the mid-5th century. Their inventory is exceptional not only by contemporary Thracian, but even Mediterranean standards. According to the archaeologist Tonkova they contained "splendid sets of head and body ornaments, consisting of numerous hoop or boat-shaped earrings, pendants for earrings, a necklace, a torque, bracelets, finger-rings, chains with pendants and fibulae, and pectorals." Most Thracian elite tombs have been identified as warrior burials as they contained weapons and gold pectorals. Two burials from Svetitsa (second half of the 5th century BC) and Dalakova (early 4th century BC) also contained finely crafted and rather impressive gold funeral masks.
