This work represents a distinctive school of alchemy -- it belonged to a period that had inherited a bitter experience of the failures, impostures, and misery surrounding the "Magnum Opus" and its mystical quest. The treatises contained in this volume are by the authors of historical legend: John de Mehung, Nicholas Flamel, Basil Valentine, Eirenaeus Philalethes, Helvetius, Michael Maier, Michael Sendivogius, Nicholas Barnaud Delphinas, and Basilius Valentinus. Illustrated.
