DEULTUM (Lyudmil Vagalinski – lvagalin@techno-link.com, Ivo Cholakov) The chronology of the excavated sites is based on 155 stratified bronze coins. Site 1. Second Eastern Gate of Deultum. A clay floor level of a fire, which was registered in 2005 and was dated to the first half of the 2nd century AD, was discovered at 4.60 m in depth to the west of the gate. The dates of the structures, located within the gate interior and to the north of it, were clarified. The gate was constructed in the second half of the 5th century AD. A fire, which was registered immediately below the floor of the gate, occurred after AD 457. An earlier fire occurred during the second half of the 5th century AD. A previous fire occurred after AD 425. Most likely, attacks carried out by Huns and Ostrogoths were the reasons for the fires during the 5th century AD. An earlier fire occurred after AD 383. A three-rim arrowhead, typical of the Huns, was found in the debris. A previous fire occurred between AD 351 and 355. Three more layers with traces of fires were explored below. The fires occurred after AD 218, after AD 155 and before AD 156 (during the first half of the 2nd century AD). Site 7. Western Gate of Early Byzantine Deultum. The gate is situated at c. 100 m to the west of the southern one of the two gates on the eastern fortification wall. A square tower, which has a size and construction technique identical to the towers of the opposite eastern gate, was discovered. A rectangular room of the 5th century AD was explored. It was transformed into a cistern and set on fire after AD 498. A wall adjoins the eastern side of the room. It was covered by a layer of fire that occurred after AD 547. The possible reason for the fire was the attack of the Kutrigurs, who were part of the proto-Bulgars, either in AD 552, or in AD 558/559. Oak and ash-tree grew in the region during the 5th – 6th centuries AD. The fauna of the 2nd – 5th centuries AD includes ox, horses, donkeys, sheep, goats, pigs, hens, boars and fallow deer.
