Karlsson’s books have the habit of going out of print and becoming very expensive. His first book from 2002 Uthark, Nightside Of The Runes is one such work. The German translation Uthark, Schattenreich der Runen from 2004 is more affordable, but it appears that the author wanted to make the English text available again. This makes the first part of this book.
The second part is Karlsson’s book about Johannes Bureus which has been published in Swedish (2005), German (2007) and Italian (2007). Now finally, this book has been made available for people who do not master these languages. That also means that this is the most extensive information available about Bureus in English.
“Uthark” refers to the theories of Sigurd Agrell (1881-1937) who theorized that there was an exoteric and an esoteric rune row. The first stats with the F-rune, in the second, this F-rune is placed at the end. To this he connected numerological and esoteric explanations that Karlsson finds convincing enough to create a magical handbook based on the system. This has a bit too much of a ‘Flowers-feeling’ to me.
