The logo is a pair of runes from a set of 18 Armanen runes created by Guido von List in 1906. It is similar to the ancient Sowilō rune, which symbolizes the sun, but was renamed as "Sig" (victory) in List's iconography.[358] The Totenkopf symbolized the wearer's willingness to fight unto the death, and also served to frighten the enemy.[359]
