Hicesius (Greek: Ἱκέσιος) was a Greek physician, who lived probably at the end of the 1st century BC, as he is quoted by Crito,^[1] and lived shortly before Strabo. He was a follower of Erasistratus, and was at the head of a celebrated medical school established at Smyrna.^[2] He is several times quoted by Athenaeus, who says that he was a friend of the physician Menodorus;^[3] and also by Pliny, who calls him "a physician of no small authority."^[4] There are extant two coins struck in his honour by the people of Smyrna.
