DEYSCORIDES. Dioscorides Pedanius of Anazarbus, fl. first century A.D., was a Greek physician during the reigns of the Roman emperors Claudius and Nero, A.D. 41-68. He says that he served in the Roman army. His work Materia Medica in five books describes six hundred varieties of plants and their medical properties. Illustrated by a Byzantine artist as early as A.D. 512, regarded as the chief work on pharmacology during the Middle Ages, it was also very much in use during the Renaissance.

Deyscorides appears among the Physician's authorities, Gen Prol 430.

The form, a pronunciation variant, occurs medially.
