Themison of Laodicea

Themison of Laodicea (, "gen." Θεμίσωνος; fl. 1st century BC) was the founder of the Methodic school of medicine, and one of the most eminent physicians of his time.
Biography.
Themison was a native of Laodicea in Syria, and a pupil of Asclepiades of Bithynia. Nothing more is known about the events of his life except that he seems to have travelled a great deal; as he mentions Crete and Milan, apparently as an eye-witness. Neither is it certain if he ever visited Rome, though it is perhaps more probable that he did so. He differed from his teacher on several points in his old age, and became the founder of a new sect called the Methodic school ("Methodici"), which long exercised an extensive influence on medical science. He wrote several medical works, but in what language is not mentioned; of these only the titles and a few fragments remain, preserved principally by Caelius Aurelianus, for example: "Libri Periodici"; "Epistolae" in at least nine books; "Celeres Passiones" in at least two books; "Tardae Passiones" in at least two books; "Liber Salutaria"; "De Plantagine".
He was perhaps the first physician who made use of leeches, and he is said to have been attacked with hydrophobia, and to have recovered. Eudemus and Proculus are said to have been followers () of Themison, which may only mean that they belonged to the Methodic school.
Themison was criticized by Soranus for his cruel handling of mental patients. Among his prescriptions were darkness, restraint by chains, and deprivation of food and drink. Juvenal satirized him and suggested that he killed more patients than he cured, but whether he means this Themison or some contemporary is unknown.
