Heroic burials The graves of Thracian mythical heroes were places of worship around which shrines were built, and where prayers were offered to the heroes and protectors and miracles were held to occur. The burial mound of Orpheus therefore was a shrine where sacrifices and other rituals in honour of the god were performed. According to one account by Pausanias, a shepherd once fell asleep while leaning on Orpheus's shrine, and during his sleep he started singing the songs of Orpheus while nightingales sang on his grave.

A tumulus mound was then raised over the burial site and games were held, with the greatest prize set aside for single combat.

His other wives would be given to his friends who would leave wedding gifts on the tomb or challenged the dead king to a duel. The mural of the Kazanluk tomb is also a depiction of the ritual divine
