People of all ages and social statuses were depicted in the art of the Hellenistic age. Artists such as Peiraikos chose mundane and lower class subjects for his paintings. According to Pliny, "He painted barbers' shops, cobblers' stalls, asses, eatables and similar subjects, earning for himself the name of rhyparographos [painter of dirt/low things]. In these subjects he could give consummate pleasure, selling them for more than other artists received for their large pictures" (Natural History, Book XXXV.112). Even barbarians, such as the Galatians, were depicted in heroic form, prefiguring the artistic theme of the noble savage. The image of Alexander the Great was also an important artistic theme, and all of the diadochi had themselves depicted imitating Alexander's youthful look. A number of the best-known works of Greek sculpture belong to the Hellenistic period, including Laocoon and his Sons, Venus de Milo, and the Winged Victory of Samothrace.
