Masonry is permeated with powerful verbal and pictorial symbolism that arouses the mental, spiritual and intellectual life. One of the treasures of the SJ USA Supreme Council's Archives at the House of the Temple in Washington, D.C., is Albert Pike's manuscript of The Book of the Words. The book was originally printed, in an edition limited to 150 copies, in 1874. This remarkable study is an exploration of the symbolic words in Freemasonry. It gives the correct spelling of, and analyzes all the "significant words" in the Scottish Rite from the 1st through the 30th degrees inclusive. Pike explores and explains their origin (Hebrew, Samaritan, Phoenician and English), meaning, symbolism and relevance to the degrees and gives his insights. In addition to being an etymological dictionary Pike explains why any given word was chosen for a given degree, thereby revealing the hidden symbolism of each word.
