Query: Cassic study

This is an important work, which provides a useful summary of what is known about the Runes. While some elements have been questioned since (the meaning of erilaz for emxample), the work as a whoe is quite solid.The book covers all of the historic futharks, the main sources of our knowledge, and various trends regarding the development of the inscriptions. However, some elements of historical linguistics are not addressed (what is the relationship of the language of the Elder Futhark inscriptions to the other Germanic language branches, for example*).Of the greatest interest are the sections discussing the names of the staves, and the origin of Runic writing.This is a truly classic study and I highly recommend it.
