Buch der heiligen Dreifaltigkeit (Book) AKA Book of the Holy Trinity
Buch der heiligen Dreifaltigkeit
1410 AD - 1433 AD
AKA Book of the Holy Trinity
Early 15th-century alchemical treatise, attributed to Frater Ulmannus (latinization of the German given name Ulmann, from OHG uodal-man), a German Franciscan
The treatise describes the alchemical process in terms of Christian mythology. The theme of the book is the analogy of the passion, death and resurrection of the Christ with the alchemical process leading to the lapis philosophorum.
It is not atypically a combination of alchemy and Christian mysticism. Ganzenmüller (1956) speculated that the book may have been known to Jakob Böhme.
