in love with Cleopatra Eurydice niece of Attalus These many marriages were analogous to that of Pallene and Cleitus, and were contracted out of the belief that ritual union with the Mother Goddess, that is the daughter of a royal family, was necessary to validate the new king's rule over her land. Treasure burial One of the most important royal rituals among the Thracians was the burial of sacred treasure, which represented the hearth-goddess , who was the goddess of the centre of things, the home, the proper, the familiar, and of wealth. The burial of the treasure symbolising the goddess therefore created a centre for a specific area, and therefore constituted the appropriation and "familiarisation" of this territory. The ritual of burying and finding the treasure represented a sacred marriage between the king and the hearth-goddess, and by this act, the king legitimised his power over his own territories or his new conquests, and renewed his royal privileges. This ritual was connected to the hearth-goddess's role as the embodiment of the "autochthonic principle," whose importance is reflected across various Indo-European religions by the emphasis on the hearth-goddess in the rituals through which kings would take over new territory: according to legend, the Argive Perdiccas I used his knife to cut a circle on the floor around the hearth of the king of Lebaea before becoming king of Macedonia among the Scythians, a substitute ritual king would ride around a group of sacred objects believed to be gifts from (the Scythian hearth-goddess) to mark the boundaries of his kingdom whenever the Macedonian king Philip II conquered or sought to conquer a new country, he would marry its princess, that is he would ritually unite with its local personification of Hestia (the Greek hearth-goddess) The priest-king The institution of the high priest-king, within whom both religious and political power had been merged, was present throughout all the Thracian peoples and tribes: The chieftains of the Scaeii and the Cebrenii were priests of "Hera" (that is the goddess ) The Orysian king Cotys I was similarly a king-high priest The Odrysuab king Seuthes II's feast as described by Xenophon had all the trappings of a sacrificial ritual carried out in a hall built specifically for such a purpose, thus attesting to Seuthes's position as a king-high priest The king of the Caeni tribe, Diegylis, while going to celebrate a wedding, once captured
