'Muhammad ibn Umail lived most probably in the first half of the 10th century....He wrote works which belong to the mystical-religious branch of alchemy....Ibn Umail tries to describe his inner experience of the stone of the sages with the help of symbols and analogies. The text...is commented on by Dr Marie-Louise von Franz...and the translation is that which she used....The commentator penetrates the enigmatic text with her excellent knowledge of Greek and Latin alchemy, as well as her personal experience of alchemical symbols and the work with people's dreams in her private practice.'
