AUGUSTA TRAIANA (Dimiter Yankov – dimiter_yankov@yahoo.com) The northern part of the room with the mosaic floor was explored. A panel of the mosaic was discovered in the central part of the room and another panel was found to the east, accommodating an octagonal pool. The mosaic floor shows geometric decoration on the periphery and a Dionysiac scene in the central panel. The geometric decoration included crosses within circles, interweaved swastikas and circles, and Vitruvian scroll. The central panel is 1.16 m wide and shows a Dionysiac procession led by a Satyr holding a shepherd’s crook, followed by two dancing Maenads. The first Maenad is holding music instruments in both hands, and the second one is holding castanets. The pool is 20 cm deep and has marble floor, while the water was provided through a lead pipe. The pool was surrounded by a band of ochre tesserae, depicting four vessels in the corners. The mosaic dated to AD 350 – 375, probably during the reign of Julian, and indicated the power of the pagan traditions during the Early Christian period.
