Use of knots

During the series you can see characters wearing belts with a particular knot twisted after the buckle, this is clearly visible in most knights. The knot is actually correct and used in medieval times, often referred as a garter and used to fix leg armour pieces to the knights' legs below the knees. It is one of the symbols of the English "Order of the Garter", the highest Chivalry Order founded in 1348 by the English King Henry III in the early stages of the Hundred Years War with France. The Arms of the Order of the Garter is a blue belt, or garter, with this same characteristic knot seen in the TV series. An example can also be seen in the tomb of one of the Order founders, Sir Reginald of Cobham, at Lingfield Church in Surrey, his effigy has the garter below his left knee.
