The banner strictly speaking dates back to the early 15th century, when the supporters of the Duke of Burgundy adopted the badge to show allegiance in the Armagnac–Burgundian Civil War. It represents the cross on which Andrew the Apostle was crucified. The design is a red saltire resembling two crossed, roughly-pruned, branches on a white field. In heraldic language, it may be blazoned argent, a saltire "ragulée" (or raguly) gules.
