During my early days on the internet I had an interest in all kinds of things esoteric. I soon found Adam McLean’s Alchemy website which he started in 1995. McLean was mostly known for coloring alchemical drawings that most knew only in black and white. This was but on small part of the alchemical investigations that McLean has undertaken since the 1970’ies (!).
The website still looks pretty much like it used to. An html website with images for navigation. Now I see that the author gives urls on his website in his many books, I get an idea why that never changed.
For many years I forgot about McLean and his website even though I do buy an occasional book about Alchemy. Recently I thought to see what books are available and I noticed that there are several study courses. Some somewhat expensive, but this particular one is well-priced.
