Krateuas (Crateuas) 120 B.C.
Krateuas was physician in ordinary to Mithridates VI Eupator, King of Pontus (died 63 B.C.). Krateuas described as well as illustrated plants. Some fragments of his writings have been recognized in the Anicia Codex of Dioscorides in the Vienna State Library to which reference has been made above. Krateuas presumably produced the figures in natural color and they were continuously copied in many manuscripts and printed herbals from the 6th Century on. Krateuas is mentioned by Pliny.
