Sergey M. Teleguin's new book is devoted to alchemy. It differs from many books about alchemy published recently. Its main merit is that this book is not "about alchemy", but in the true sense of alchemy. Its author not only studied alchemical treatises, but also participated in alchemical experiments. The book is written on the basis of personal impressions obtained in the experiments with alchemical mirrors and the experience known as "dissolving the body of the King in a bloody font". This book has been translated with Artificial Intelligence.
