The Uthark theory about the runes holds that the rune row is a cipher, and that one can understand its meaning by placing the first rune, "F", last, resulting in an ”Uthark” instead of the traditional "Futhark" order. It originated in the 1930s with the work of philologist Sigurd Agrell (1881–1937), a professor at Lund University, Sweden. His suggestion has no support in historical sources and was never accepted in mainstream runic studies, but it has found proponents in occult, esoteric circles and in popular culture.
