EXPLORATIONS OF TUMULUS NO. 4 NEAR DEULTUM (Petar Balabanov – p_balabanov@abv.bg) Sixteen burials were discovered and so, their total number within the tumulus reached 22. Constructions of boulders and broken stones were excavated below three of the primary small mounds incorporated within the tumular embankment. The first construction is situated in the tumular center. Skeletons of adults in a Hocker position were discovered within the first and the second construction, which is located to the northeast of the first one. Single human bones were found in the third construction. The sherds found in the constructions show that they date to the Roman period. The deceased persons were oriented to the west. Four platforms of boulders and broken stones in the southern part of the tumulus and a ritual pit were related to the graves. Single human bones of two individuals (a man and a woman) were found in a small trench dug into the bedrock on the bottom of the ritual pit. Seven burials of the 1st – 2nd centuries AD were discovered in the southern and southeastern part of the tumulus. Three of them were cremations on pyres and contain rich grave goods: a bronze anthropomorphic unguentarium decorated with the faces of Dionysos, Pan and Silenos, a pair of gold earrings and an open-work gold pendant, two bronze strigiles (one of them decorated), glass and terracotta unguentaria, etc. The coins found in the graves allow us to date the burials between AD 96 and 150. The other four graves excavated in the same part of the tumulus were inhumations and date between AD 70 and 170. Four inhumation burials were explored in the northern part of the tumulus. The deceased were rested in burial pits with their heads oriented to the west. Iron nails were driven in the bodies of the deceased in two of the burials: a nail was driven in the crown of the skull and ten nails were symmetrically driven in the both sides of the bodies.
