EXPLORATIONS OF TUMULUS NO. 4 AT DEULTUM (Peter Balabanov – p_balabanov@abv.bg) Two burials were discovered in the central part of the tumulus under the stone pavement. Grave No. 10 lies below the southeastern periphery of the pavement. An inhumation burial in Hocker position lying on the right side, with head pointing to the west, was discovered inside the burial pit. Grave No. 12 lies below the southwestern periphery of the pavement. The deceased was placed in a burial pit, in Hocker position lying on the right side, with head pointing to the west. Ash layer spread over the stone pavement was discovered in square No. 16. A ridge-roofed grave covered with tegulae and oriented southeast – northwest was explored in square No. 25. An inhumation burial of an adult, lying on his back and with head pointed to the northwest, was discovered in a burial pit, oriented southeast – northwest, located to the north. The burial cuts an earlier grave pit containing an inhumation burial in Hocker position. A burial of a child was explored in a grave pit, oriented east – west, in square No. 16. Another inhumation burial of a child, oriented southeast – northwest, was discovered in square No. 65. Five single-type graves (shallow burial pits dug into the ground) were discovered below the stone constructions in the northern part of the tumular embankment. Four of the burials contained deceased persons in Hocker position, while one of them was decapitated. The fifth burial contained a young person lying on his back with hands stretched alongside the body. Four ritual pits were explored. One of the pits contained human bones of two adults, while another two contained hand-made sherds. The burials dug into the ground below the tumulus date to the Late Bronze and Early Iron Ages (from c. 1500 to 500 BC), while the rest of the burials date to the 1st – 4th centuries AD. The tumulus was constructed at the end of the 4th century AD.
