 In contrast to the fragmentary evidence that we possess for the philosophers of the Old and Middle Stoa, we have substantial writings from a number of Roman Stoic philosophers. Two of them wrote in Greek,  Epictetus  (circa 55–155 CE) and the Roman emperor  Marcus Aurelius  (121–180 CE), while the third wrote in Latin,  Lucius Annaeus Seneca  (4 BCE–65 CE). Other Roman Stoics whose works have not been so well preserved include Musonius Rufus (c. 25–90 CE) and Hierocles the Stoic (c. 150 CE – not to be confused with the 5th century Neoplatonist of the same name who wrote a commentary on the ps-Pythagorean ‘Golden Verses’).
