However, another theory suggests that the purpose of his journey to the high mountains was to communicate with the spirit world. Ötzi was also found equipped with a perforated bead of white marble with twisted leather tassels. Furthermore, he had a few body tattoos and some unfinished hunting equipment, which together might support the idea that he was a ritual specialist. Though the idea of him being a shaman is only supported by the unique discoveries made near him, it cannot be overlooked, as bright (or polished) stones are often held to have spiritual power. Walter Leitner, from the University of Innsbruck, Austria has come forward with an interesting theory which suggests that Ötzi was a shaman and was killed by his enemies in order to end his reign.
