The Sacred Scrolls of the faith of the Lords of Kobol, used on-screen in Battlestar Galactica. This is the form of the scrolls I personally prefer visually, even though I would like a book version as well for more practical reading.
The Sacred Scrolls are a set of writings that form the basis of Colonial religion, a polytheistic faith resembling the legends of ancient Greece. The scrolls record much of the alleged history of humanity, including life on Kobol before the great exodus, and the legend of Earth. Portions of the scrolls are used in religious ceremonies, such as the Service for the Dead.
Most notable among the Sacred Scrolls is the Book of Pythia, also referred to as the Pythian Prophecy. Written 3,600 years ago by the oracle Pythia, they are believed by some to foretell the current exodus from the Twelve Colonies of Kobol.
