Philinus of Cos (Greek, Modern (1453-);: Φιλῖνος ὁ Κῷος; 3rd century BC) was a Greek physician. He was the reputed founder of the Empiric school. He was a pupil of Herophilus, a contemporary of Bacchius, and a predecessor of Serapion.[1] He wrote a work on part of the Hippocratic collection directed against Bacchius,[2] and also one on botany,[3] neither of which has survived. It is perhaps this later work that is quoted by Athenaeus,[4] Pliny,[5] and Andromachus.[6]
