In ancient Greece, long male hair was a symbol of wealth and power, while a shaven head was appropriate for a slave. The ancient Greeks had several gods and heroes who wore their hair long, including Zeus, Achilles, Apollo, and Poseidon. Greek soldiers are said to have worn their hair long in battle. Such warriors considered it a sign of aristocracy and are said to have combed it openly in order to show off. Also, in order to keep enemies from getting a hold of it in battle, they were known to cut the front short, but leave it long in the back, where it was more out of reach (mullet). A widely held alternative interpretation of the conventional belief is that they kept it long, and simply tied it back in a style known as a ponytail in order to keep it out of their enemies' reach. The ponytail method allowed warriors, who often traveled to battle with a minimal amount of equipment in order to avoid excessively heavy loads over long marches, to keep their hair manageable with a small piece of string to hold their pony tail in place and a knife to cut the back to length with one simple slice. Around the sixth century, however, the Greek men shifted to shorter hairstyles, with the exception of the Spartans. Women in the culture remained with the longer style, which for them showed freedom, health, and wealth, as well as good behavior. In men, long hair was considered a sign of false pride by this time.
