Men also commonly wore beards during the Safavid and Qajar eras. The ancient Greeks regarded the beard as a badge or sign of virility; in the Homeric epics it had almost sanctified significance, so that a common form of entreaty was to touch the beard of the person addressed. It was only shaven as a sign of mourning, though in this case it was instead often left untrimmed. A smooth face was regarded as a sign of effeminacy. The Spartans punished cowards by shaving off a portion of their beards. From the earliest times, however, the shaving of the upper lip was not uncommon. Greek beards were also frequently curled with tongs. In the time of Alexander the Great the custom of smooth shaving was introduced. Alexander strongly promoted shaving during his reign because he believed it looked tidier. Reportedly, Alexander ordered his soldiers to be clean-shaven, fearing that their beards would serve as handles for their enemies to grab and to hold the soldier as he was killed. The practice of shaving spread from the Macedonians, whose kings are represented on coins, etc. with smooth faces, throughout the whole known world of the Macedonian Empire. Laws were passed against it, without effect, at Rhodes and Byzantium; and even Aristotle conformed to the new custom, unlike the other philosophers, who retained the beard as a badge of their profession. A man with a beard after the Macedonian period implied a philosopher, and there are many allusions to this custom of the later philosophers in such proverbs as: "The beard does not make the sage." Shaving seems to have not been known to the Romans during their early history (under the kings of Rome and the early Republic). Pliny tells us that P. Ticinius was the first who brought a barber to Rome, which was in the 454th year from the founding of the city (that is, around 299 BC). Scipio Africanus (236–183 BC) was apparently the first among the Romans who shaved his beard. However, after that point, shaving seems to have caught on very quickly, and soon almost all Roman men were clean-shaven; being clean-shaven became a sign of being Roman and not Greek. Only in the later times of the Republic did the Roman youth begin shaving their beards only partially, trimming it into an ornamental form; prepubescent boys oiled their chins in hopes of forcing premature growth of a beard.
