AQUAE CALIDAE – THERMA (Dimcho Momchilov – karnobat.muzey@mail.bg, Miroslav Klasnakov, Yavor Rusev) The explorations in the southeastern part of the Roman and Early Byzantine thermae continued. The exploration of the wall, 2.50 m wide and discovered in 2012, continued. A patch of burned roof structure was partly explored in front to the south of the wall. A marble slab with inscription of the AD 20s by Apollonios son of Eptaikenthos, was discovered. It was devoted to the Thracian King Rhoimetalkas II (c. AD 19 – 36) and his wife Pythoris at the altar of Demeter. Another fragment of a marble slab with partly preserved Greek inscription was found, containing the Thracian name Eptaikenthos. A marble votive relief of the Thracian Horseman of the Roman period was discovered in a Late Antique layer of building material. The extension of the Roman or Late Antique water-conduit No. 4 was documented in Trench D6. The exploration of the pool discovered in 2013, was completed. It was 1.30 m deep, with marble steps and bottom paved with marble tiles. The pool in Trench A3 was entirely explored. It measured 3.60 m by 1.20 m and was 54 cm deep. Judging from the sherds and a gold tremissis of Justin II, the pool dated to AD 550 – 575. A pool with marble steps was partly discovered in Trench B3. It belonged to the earliest baths. A fragment from a building inscription dated to AD 60 – 68 probably featured the building of baths on behalf of Nero. The explorations showed several reconstructions of the thermae during the Early Byzantine period.
