J. R. R. Tolkien's books are full of Norse mythology. Gandalf is basically Odin who can read & signs his name in Runes

R. R. Tolkien for the constructed languages he devised and used in his works. Cirth is written with a capital letter when referring to the writing system; the letters themselves can be called cirth."
The Cirth is not the only runic writing system used by Tolkien in his legendarium. In fact, he devised a great number of runic alphabets, of which only a few others have been published. Some of these are included in the "Appendix on Runes" of The Treason of Isengard (The History of Middle-earth, vol. VII), edited by Christopher Tolkien.[19]
According to Tolkien himself, those found in The Hobbit are a form of "English runes" used in lieu of the Dwarvish runes proper.[20] They can be interpreted as an attempt made by Tolkien to adapt the Fuþorc (i.e., the Old English runic alphabet) to the Modern English language.[21]
These runes are basically the same found in Fuþorc, but their sound may change according to their position, just like the letters of the Latin script: the writing mode used by Tolkien is, in this case, mainly orthographic.[22]
This means that the system has one rune for each Latin letter, regardless of pronunciation
Tolkien devised this runic alphabet in a very early stage of his shaping of Middle-earth. Nevertheless, they are known to us from a slip of paper written by J.R.R. Tolkien, a photocopy of which Christopher Tolkien sent to Paul Nolan Hyde in February 1992. Hyde then published it, together with an extensive analysis, in the 1992 Summer issue of Mythlore, no. 69.[24]
The system provides sounds not found in any of the known Elven languages of the First Age, but perhaps it was designed for a variety of languages. However, the consonants seem to be, more or less, the same found in Welsh phonology, a theory supported by the fact that Tolkien was heavily influenced by Welsh when creating Elven languages
