Bono, Peter. A Lombardian; a great adept in the Hermetic Science, who travelled to Persia to study Alchemy. Returning from his voyage he settled in Istria in 1330, and became famous as a Rosicrucian. A Calabrian monk named Lacinius is credited with having published in 1702 a condensed version of Bono’s works on the transmutation of metals. There is, however, more of Lacinius than of Bono in the work. Bono was a genuine adept and an Initiate ; and such do not leave their secrets behind them in MSS.
