Deep magic
From Free net encyclopedia
In computer programming, deep magic refers to techniques that are not widely known, and may be deliberately kept secret. The number of such techniques has arguably decreased in recent years, especially in the field of cryptography, many aspects of which are now open to public scrutiny.
In fiction, the term comes from The Lion, the Witch and the Wardrobe, the first book in C.S. Lewis' The Chronicles of Narnia, which describes ancient laws and codes as "deep magic from the beginning of time." It is also the name of an e-zine based on high fantasy and science fiction inspired by Lewis' work.
