Austria in the late 19th and early 20th century was the Austrian occultist, mysticist, and völkisch author, Guido von List. In 1908, he published in Das Geheimnis der Runen ("The Secret of the Runes") a set of eighteen so-called, "Armanen runes", based on the Younger Futhark and runes of List's own introduction, which allegedly were revealed to him in a state of temporary blindness after cataract operations on both eyes in 1902. The use of runes in Germanic mysticism, notably List's "Armanen runes" and the derived "Wiligut runes" by Karl Maria Wiligut, played a certain role in Nazi symbolism. The fascination with runic symbolism was mostly limited to Heinrich Himmler, and not shared by the other members of the Nazi top echelon. Consequently, runes appear mostly in insignia associated with the Schutzstaffel ("SS"), the paramilitary organization led by Himmler. Wiligut is credited with designing the SS-Ehrenring, which displays a number of "Wiligut runes". Modern neopaganism and esotericism Runes are popular in Germanic neopaganism, and to a lesser extent in other forms of Neopaganism and New Age esotericism. Various systems of Runic divination have been published since the 1980s, notably by Ralph Blum (1982), Stephen Flowers (1984, onward), Stephan Grundy (1990), and Nigel Pennick (1995). The Uthark theory originally was proposed as a scholarly hypothesis by Sigurd Agrell in 1932. In 2002, Swedish esotericist Thomas Karlsson popularized this "Uthark" runic row, which he refers to as, the "night side of the runes", in the context of modern occultism. Bluetooth The Bluetooth logo is the combination of two runes of the Younger Futhark, hagall and bjarkan, equivalent to the letters H and B, that are the initials of Harald Blåtand's name (Bluetooth in English), who was a king of Denmark from the Viking Age. J. R. R. Tolkien and contemporary fiction In J. R. R. Tolkien's novel The Hobbit (1937), the Anglo-Saxon runes are used on a map and on the title page to emphasize its connection to the Dwarves. They also were used in the initial drafts of The Lord of the Rings, but later were replaced by the Cirth rune-like alphabet invented by Tolkien, used to write the language of the Dwarves, Khuzdul. Following Tolkien, historical and fictional runes appear commonly in modern popular culture, particularly in fantasy literature, but also in other forms of media such as video games (for example the 1992 video game Heimdall used it as
