Ancient helmets are a kind of defense that soldiers used for protecting their heads in battle. The first helmet appeared in the 8th century B.C. It protected the entire head, covering the nose along with the cheeks, while the eyes and mouth were uncovered. These defensive weapons were mainly made of metal or bronze and often had a horse tail crest on their top. The first designs were very simple, but as time passed on, they evolved. The first form of ancient helmet originated from Corinth and it was the most popular of them all since it was used until the end of the Greek-Persian wars, in the mid-5th century. Other types of helmet built in ancient Greece were Illyrian, Chalkidonic and Thracian. The use of helmets is also found in medieval battles during the Middle Age.
