The labryinth is a winding, maze-like path, often resembling a spiral. Labyrinths are found in many ancient cultures, and almost always have spiritual significance. Nearly identical labrynth patterns are found in neolithic art, on native American petroglyphs, and even in ancient Vedic sites. Ancient Minoan labrynths were associated with the cult of the mother Goddess, and were possibly used in intiatory rituals.
Labyrinths carried into medieval times, where they were often laid on the floors of cathedrals. They were used as a sort of miniature pilgrimage- often, these 'pilgrims' traveled the path on their knees while praying continuously. Labyrinths today have seen a kind of revival- they are common today both in churches and Neopagan sanctuaries.
