EXPLORATIONS IN DEULTUM (Krasimira Kostova – kr.kostova@mail.bg, Elka Docheva, Maria Manolova-Voikova) The explorations continued in front of the eastern Early Byzantine fortification wall and inside the fortified area. In 2006, a stratum with a semi-dug sunken-floored house of the 9th – 10th century AD was explored on the inner side of the fortification wall. A stratum with traces of fire of the end of the 6th century AD, dated by coins minted by Emperors Justin II and Sophia, was reached. In 2007, two parallel walls, built of stones bonded with mud, were discovered under the stratum. Four drain pipes, which led the waste water out of the fortification walls, were discovered under the foundation of the western wall. Pieces of mortar and fragmentary plaster painted in Pompeian red were found in a destruction deposit 60 – 83 cm thick. The mortar floor of the baths was discovered under the destruction deposit. Fragmentary plaster painted in Pompeian red was found fallen on the floor. In 2006, the eastern face of the fortification wall, built over a room with hypocaust belonging to the baths, was explored. In 2007, a stratum 60 – 85 cm thick, containing amphorae sherds, was explored. In 2005, the stratum was dated to the 8th century AD by a coin of Emperor Leo III. The level of the fortification wall was reached. An occupation level of the middle of the 5th century AD with traces of fire, dated by coins of Emperors Theodosius II and Valentinian III, was explored below the level of the fortification wall. A place for mixing mortar, containing coins of Emperor Valens, was discovered. The stratum contained pottery, amphorae, including a Gaza amphora, and terracotta lamps, including a Corinthian lamp showing Serapis with two cobras and a male personage. The baths were destroyed at the end of the 4th – beginning of the 5th century AD. The exploration of the room located to the west of the nymphaeum, which was excavated in 1988, was resumed. The finds include sherds, terracotta lamps, an amphora of Dressel 24 type and a carnelian gem.
