Cheveron

Among the pieces laid on a shield, the ordinaries, William St John Hope counts the cheveron, “formed of two strips issuing from the lower edges of the shield and meeting in a point in the middle, like the cheverons forming the roof timbers of a house.” Here it is argent on a field of vert. Hope gives no rule for drawing it, so the construction here is our own, and it is exact. The shield is laid out as for gyronny, from a line down the middle as long as the shield is wide, so that the top edge, the sides and the level line through the middle make two squares. Their diagonals cross at the centres of the squares, and the line through the two centres halves the middle line; a swing of that half about the top of the middle line halves the top edge. The upper edge of each leg runs from the half way point of the top edge on the other side through the half way point of the middle line. Its lower edge is a diagonal of a square, from the top corner on the other side through the point where the middle line meets the level line. Both run on to the flank at forty five degrees, so the cheveron is a quarter of the width deep on the middle line.
