Your grandma's crystal gazing books, now available online

There are many in-depth texts about crystal gazing that were published before 1923 and have since passed into the public domain in the United States.  Several are available for download free of charge from various places.  Some of these books contain timeless information that remains helpful for the modern student.  Others are full of quaint and superstitious ideas, but still delightful as historical curiosities.  (Many contain a mixture of both!)  Here are some, in no particular order, for your handy perusal (in case of broken links, try googling the title and author):


Sepharial (pseudonym of Walter Gorn Old).  How to Read the Crystal, or Crystal and Seer. 1922.

Frater Achad (Charles Stansfeld Jones).  Crystal Vision Through Crystal Gazing.  1923.  (Also in PDF.)


William Walker Atkinson and L.W. de Laurence. Practical Psychomancy and Crystal Gazing. 1907.

Catherine Yronwode has compiled a more extensive bibliography, (but no links or texts), which includes descriptions of the original published editions for collectors and book nerds.
