Alexias (Greek: Greek, Ancient (to 1453);: Ἀλεξίας) was an ancient Greek physician who was a pupil of Thrasyas of Mantinea, and lived probably around the middle of the 4th century BC.[1] Theophrastus mentions him as having lived shortly before his time, and speaks highly of his abilities and acquirements.[2] He was said to have equalled his master Thrasyas in the science of botany, and to have exceeded him in other areas.[3]
