Golden Chain of Homer: Now Available!
When works of alchemy are made, mostly they fixate on obscure philosophy- the only exceptions I have encountered are this work and some of Paracelsus' materials. The Golden Chain of Homer, however, is explicit and describes actual alchemical experiments and their recipes.
For those interested in alchemy this work is highly recommended; it may be seen as a somewhat dense but spectacular overview of the philosophy and the working of alchemy itself. Disclaimer: I in no way endorse the practice of these experiments.
