Scribonius Largus Designatianus (c. 1 – c. 50) was the court physician to the Roman emperor Claudius.
Around 47 AD, at the request of Gaius Julius Callistus, the emperor's freedman, he drew up a list of 271 prescriptions (Compositiones), most of them his own, although he acknowledged his indebtedness to his tutors, to friends, and to the writings of eminent physicians.
The work has no pretensions to style, and contains many colloquialisms,[2] and has been cited by Peter Suber as a forerunner of Open Access.
[3] The greater part of it was transferred without acknowledgment to the work of Marcellus Empiricus (c. 410), De Medicamentis Empiricis, Physicis, et Rationabilibus, which is of great value for the correction of the text of Largus.
[6] Largus is credited with an early description peripheral nerve stimulation in the form of shocks from electric fish to provide relief from gout and headaches.
