I ended up reading the lodestone section and realizing that it was a description of magnets.
- olooney 7y agoMagnets were well known the Greeks in antiquity[1], likely because of the Magnesia region in Greece where natural magnets are commonly found[2]. Words like "magnet" and "magnetite" are named after that region. In 1584, the magnetic compass would have been well known and understood, but the connection between electricity and magnetism was a long way off. Gilbert's De Magnete[4], which explained that compasses worked because the earth itself had a magnetic field, was published in 1600, not long after this book on "Magick."
