I have just started on designing my 1st ever replica Scottish targe , actually two of them will be made one by my wife and the other by myself. According to research they varied in size from 45 - 55 cm in diameter and were made up from two cross sections of boards running the opposite direction for strength. They were then covered in leather with brass nails forming Celtic patterns, some were also carved as well to form more intricate designs. The backing was made up of animal hide often deer or goat and then straps were added to the back in order to carry it. They were used from the early 17th century to the battle of Culloden in 1746. The Scottish highlanders main mean of defense in battle was his targe which was designed to stand heavy blows from his opponents weapons. Some targes also utilized a metal spike which protruded from the center boss. Pictured below are a few photos of original targes now housed in museums in Scotland.
