Iron Age

Thracian history and culture are closely connected with the secret teaching of Orphism—sacred knowledge passed down orally among the Thracian aristocrats. This knowledge ensured both the balance and renewal of the world and power over the rest of the population. The Orphics believed in immortality. In their beliefs, the Great Mother Goddess stands at the foundation of everything. From her, the Sun God (Orpheus) emerges, and from their sacred union, a son is born—the earthly Thracian king. After passing through trials and performing glorious feats, he receives from the Great Mother Goddess the right to rule over the people. After his death, he returns to the depths of the earth to become the Sun God once again.

Only Thracian rulers and aristocrats could achieve perfection and immortality. They were sent to the afterlife as gods, and their people erected impressive burial mounds and monumental tombs for their bodies. In these tombs, they were laid to rest with magnificent jewelry and clothing, ceremonial weapons, rich grave goods, horses, and chariots. The idea of immortality is also embedded in the aristocratic teaching about the god Zalmoxis, venerated by the Thracian tribe of the Getae. Herodotus, the father of history, tells us that the Getae "believe that they do not die, but that the deceased goes to the god Zalmoxis." He further notes that "neither he himself, nor his table companions, nor their descendants will ever die, but will go to such a place where they will live forever and have all good things."

Cemeteries, called necropolises, were located outside settlements and cities. Depending on the burial rite, the deceased were either buried in the ground or cremated, with their bones collected in urns.

Roman Period

During the Roman period, many graves were built of stone or brick and covered with stone slabs or bricks. Wealthier citizens were buried in sarcophagi—tall stone coffins decorated with various reliefs. Burial in sarcophagi was not practiced in the Thracian lands before the Romans arrived.

Stone slabs called stelae were placed above graves. These were engraved with reliefs depicting portraits of the deceased, objects related to their professions, or symbolic scenes of them bidding farewell to loved ones during a funerary feast. Inscriptions carved into the slabs typically recorded the deceased's name, age at death, and brief details from their life. Funerary altars were also erected in memory of the dead—large cubic stone blocks engraved with reliefs and inscriptions immortalizing the deceased. These more expensive and prestigious monuments were usually reserved for wealthier individuals.

The bodies of the deceased were transported to the burial site by chariot. Archaeologists have discovered chariots near some graves that may have been used to carry the dead to the tomb. Wear and repair marks on some parts show these chariots were used during the owner's lifetime. Placing chariots in graves demonstrated wealth, prestige, and power—a practice reserved for prominent Thracian aristocrats. This ritual became most widespread during the Roman period.
