Every history of medicine scholar, who goes back further than the 19th century, runs into astrology in medicine. I desperately need to learn to read these: http://www.bl.uk/the-middle-ages/articles/medicine-diagnosis-and-treatment-in-the-middle-ages. Once I understand how the astrological charts work, I will be that much further ahead in understanding the star charts that I’m trying to read. I know that they are the key to the door that I’m standing at. I just wish I could figure it out – it’s been five years now. Eventually, I’ll shoulder the door down. Until then, I’ll work on the other manuscripts.
