Psellus here delivers one of the more in depth works on demonology which has ever been made. Categorizing demons in the form of a Socratic dialogue between Timothy and Thracian, Psellus remarks upon the form, goals, and nature of the demonic realm in all its subsets. We see here, for the more secular reader, as well, a description of possession as a de facto mental state, and a description of speaking in tongues under such power as well. Moreover, the use of mind altering substances as a way of communication with such entities is not explicit here but indeed is implied.

Isaac Hollandus remains one of the foremost names within the realm of alchemy. This work proposes, among other things, that an alchemical cure-all can be made simply by processing lead with vinegar and other materials. The danger associated with alchemy is all the more real here, where the operator is admonished to taste test compounds containing heavy metals. Beyond this, it additionally admonishes the practitioner to heal the sick, do good to the poor, and praise the Christian god.

The Universal Fortune Teller is pure Americana- a hand guide to divining the future and determining destiny through the use of tea leaves, playing cards, palmistry, astrology, and other means. Written in 1860, it is partially based on older traditions within American and English divination. From the day of the week upon which a child was born to hair color this manuscript claims many prognosticating capabilities. With a variety of charms and spells to secure love and wealth, it is properly understood as one of the foremost American occult works.

Trithemius is best known for his hidden writing- the infamous Steganographia, but his other works, including this short grimoire on the use of crystals in summoning celestial spirits, are no less potent. Through the use of a simple wand, pedestal, lamen, and a polished and clear crystal, Trithemius states that it is possible to manifest and converse with celestial forces and to constrain them through the use of simple invocation and prayer.

The Mirror of Alchemy, written in the 1541 in Latin and translated to English at the closing of the 16th century, stands out both as a misattributed work (not having actually been written by Bacon) and an exceptional, if short, guide to the process of creating elixir. Categorizing the metals according to their digestion through natural processes, it posits the replication of nature in a laboratory setting as the sole way to work with alchemical materials, through cosmic forces as then understood to be true.

The Regimen Sanitatus Salernitanum is a strange work originally delivered in the form of poetry in the 12th century. First translated into English in 1608, it takes the form of a combination dietary guide and medicinal work. Applauding the benefits of sage and wine and warning against the consumption of deer meat when ill, the regimen additionally provides an early look at sanitation; the washing of food and hands and avoiding places blighted by human waste. Such works would later inform plague treatments and the work of Nostradamus.
