Antidotarium. Add: Quid pro quo; Synonyma.

This work, which first circulated in manuscript in 1140, was the first formulary to be printed. It consists of 139 prescriptions and includes the original formula for the “anesthetic sponge” (spongia somnifera), the earliest sources of which are MSS of the 8th century. It also includes a table of weights and measures which formed the basis for the apothecaries system of weights and measures, i.e. the modern grain, scruple, dram, etc. The book must have been of great practical value, as it was one of the first medical works to be printed.
