I appreciate it. https://www.sacred-texts.com/mas/index.htm This site has a very good archive of older esoteria. The work that I drew on for this 'update' was Arthur Edward Waite's book on Rosicrucianism. In this he gives his translation of the original Latin, but the English was very outdated, making it difficult to read. One note: A.E. Waite has been criticized by other occultists for minimizing or obfuscating Rosicrucianism. Manly P. Hall, for example, cites that Waite was highly ambitious and wanted greatly to be taken seriously academically, and so he was overly cautious when discussing Rosicrucianism publicly. As far as topic headings where similar material might be found, I'd probably look at Rosicrucianism and Freemasonry. In general, the occult at this time was quite taken with all of these ideas of universal reformation - basically all of the stuff you see going on in the world. John Dee was a major figure in Elizabethan England, and there is a lot of interest about him out there. In Freemasonry, Albert Pike is a big name. I cannot recommend any specific works at this time. To be honest, I've only recently begun looking into the older publications. When you ask about similar pieces, I'm not certain exactly what it is you're interested in. If things about the occult interest you, you cannot go wrong with Manly P. Hall. A word of warning: I'm not familiar with your background and whether or not you are a religious person, or how much exposure to esoteria/occult you have. If you are a Christian and don't have a great deal of exposure to all of this thought, be careful. It can be incredibly attractive, particularly as you get into the 18th and 19th century and they begin to 'scientize' some of the spiritual content, by calling it things like 'mental science'. There are a lot of highly attractive theories going on there that clothe themselves in religious language and attempt to connect themselves to the Bible. I say this because it can lead well-intentioned people astray very easily.
