Menodotus Of Nicomedia (flourished ad 120) was a philosopher of the Skeptical school of empirical medicine, credited with elaborating the first scientific method of observation. Like many other physicians of the period, he considered medicine an art; this left him free to perfect his art while remaining a Skeptic. He also wrote against Asclepiades, who espoused Atomism and a theory of imbalance of corpuscles as the cause of illness. Some scholars think the voluminous writings of Menodotus, frequently mentioned by Galen, suggest two contemporary physicians of the same name.
