The document elaborated by this group is based in the theory that the modern Diablada has roots in the ancient rituals performed 2000 years ago by the Uru civilization. The study makes reference to a deity named Tiw who was the protector of the Urus in mines, lakes and rivers and, in the case of Oruro (or Uru-uru), the owner of caves and rocky shelters. The Urus worship this deity with the dance of the devils being the Tiw himself the main character, later this name was Hispanicized as Tío (English: uncle), and as product of the syncretism, the Tiw represented the figure of the devil regretting and becoming devotee of the Virgin of Socavón.[14]
