This little two volume book set is really a little gem for anyone’s library regarding Norse Magick and Galdrastafurs. I use it on occasion as a reference and for my own practice of Galdur and Seiðr. The great thing about these two books is that Volume 1 is a copy of the original manuscript (Lbs. 143,8vo) and Volume two is the translation in both Icelandic, English, German and Danish. It comes in a nice slip cover box as well. I highly recommend this one for your library.
