AMPHITHEATRUM SERDICAENSE (Zharin Velichkov – zharin@abv.bg) Strata of the 2nd – 3rd centuries AD were explored. Fragments of pottery, terracotta lamps, glass vessels, marble tiling, red and brown plasters, beads and slag were found. A marble statuette of Asclepius and a woman’s head from a bronze statuette were discovered. More than 40 coins were found, including sestertius minted during the reign of Claudius. Roman trade buildings and a dung-hill existed in this part of Serdica. The wall enclosing the arena of the amphitheater was discovered. Remains of the entrances to the arena were explored. The cavea was discovered. The arched double wall constructed in opus mixtum and 2.20 m in total width was traced out. The wall enclosing the arena and the arched wall were connected to each other with three radial walls constructed in opus mixtum that framed separate sectors covered with vaults. Two of the radial walls have entrances connecting the separate sectors. The earliest coins found in the amphitheater belong to Licinius I, Licinius II and Constantine I, while the latest ones were minted by Theodosius I, Arcadius and Honorius. The amphitheater stopped functioning during the second half of the 4th century AD and parts of it were reused for dwellings. Two dwellings located in the sectors of the cavea were explored. More than 40 coins of Anastasius I, Justinus I, Justinianus I, Justinus II and Phocas were found, in addition to bone plates of arches, fragmentary ceramic and glass vessels, fibulae, belt buckles and points, bone hair-combs and a medallion of Antinous minted in AD 134 – 137 that was used as a pendant during the 5th – 6th centuries AD. Two ovens and 20 coins from the end of the 10th to the first half of the 12th centuries were found in the upper strata. Buildings of the 16th – 17th centuries, ceramic and glass vessels, porcelain, terracotta tobacco-pipes and coins minted during the 15th – 18th centuries were found, too.
