Criton of Heraclea (Greek: Κρίτων, Latin: Titus Statilius Crito) was a 2nd-century (c. 100 AD) Greek chief physician and procurator of Roman Emperor Trajan (98–117) in the campaign in Dacia.
[2] He wrote a work on Cosmetics in four books, which were very popular in Galen's time and which contained almost all that had been written on the same subject by Heraclides of Tarentum, Cleopatra, and others.
Criton wrote also a work on Simple Medicines of which the fourth book is quoted by Galen;[3] he is also quoted by Aëtius and Paul of Aegina, and may perhaps be the person to whom one of the letters of Apollonius of Tyana is addressed.
Getica was at the basis of Trajan's own work, Dacica (or De bello dacico), about his Dacian Wars, which is also lost.
As Trajan's medic, Criton created a mixture consumed daily by the emperor.
