ORFFYREUS

(The frills at the beginning of the name could not be read beyond doubt in their entirety. Apparently several letters are included. Among other things, an “M”, a “D” and one (or two) “E”. The author has therefore not attempted an interpretation.) 

High Princely Hess. Comerc. Rath
M.P. Mathem. a. Invent. of the Perpet. Mobile 

High Hessian Council of Commerce, 
Medicus Practicus (Practical Physician), Mathematicus (Mathematician) and Inventor of the Perpetuum Mobile 

The name “Mathematicus” was very common in the earlier centuries, because leading this title was not regulated. In terms of his knowledge and skills, the Mathematicus was not comparable to a diploma mathematician of the present. Much of what he was concerned with would be assigned to physics today.
