The Abandoned or Lost Word

Berhard Trevisan (1406-1490) was born in Padua, Italy, into a noble family, often identified as Count of the Mark of Treviso (Treves). He devoted his life to alchemy and wrote a number of works though his name was often adopted by later writers to give their own books some gravitas.
This early seventeenth century text is probably one of those ascribed works, nevertheless, it is an interesting account of the alchemical work, dealing with the Philosophical Mercury and the Incombustible Sulphur, as components for making the Philosophers' Stone.
