Ley lines are alleged alignments of a number of places of geographical and historical interest, such as ancient monuments and megaliths, natural ridge-tops and water-fords.
The phrase was coined in 1921 by the amateur archaeologist Alfred Watkins, in his books Early British Trackways and The Old Straight Track. He sought to identify ancient trackways in the British landscape. Watkins later developed theories that these alignments were created for ease of overland trekking by line-of-sight navigation during neolithic times, and had persisted in the landscape over millennia.
In 1969 the writer John Mitchell revived the term "ley lines", associating it with spiritual and mystical theories about alignments of land forms, drawing on the Chinese concept of feng shui. He believed that a mystical network of ley lines existed across Britain. Since the publication of Mitchell's book, the spiritualised version of the concept has been adopted by other authors and applied to landscapes in many places around the world. Both versions of the theory have been criticised on the grounds that random distributions of points will inevitably create apparent "alignments".
Ley Lines in The Raven Cycle Edit
The Ley Lines in the Raven Cycle are also called the Corpse Road which fits in with some of the history of Ley Lines but not all of them. The Henrietta Ley Line is a strong source of energy, both electromagnetic and mystical. Cabeswater, the heart of the Henrietta Ley Line, is an especially energetic and volatile place. It is implied that the Ley Line in Henrietta has a consciousness, which seems to communicate through the trees in Cabeswater and other methods, including apparitions, tarot cards, and visions. It also seems to be like a miswired circuit with a desire to be fixed.
