Vert is portrayed in heraldic hatching by lines at a 45-degree angle from upper left to lower right, or indicated by the abbreviation v. or vt. when a coat of arms is tricked.
Descriptions of knightly shields as painted at least partly green in Arthurian romance are found earlier, even in the late 12th century.
[3] According to Paweł Dudziński, the chairman of the Heraldic Committee within the Polish Ministry of Interior and Administration, early heraldic green used to be bright, obtained from verdigris pigment, which allowed contrast with azure (obtained from dark ultramarine pigment) in arms that contravened the rule of tincture.
[4] An early example of a green escutcheon was that of the coat of arms of Styria,[year needed] based on the banner of Ottokar II of Bohemia (r. 1253–1278), described by chronist Ottokar aus der Gaal (c. 1315) as: A curious example occurs in an early armorial of the Burgundian Order of the Knights of the Golden Fleece (Toison d'Or) where the arms of the Lannoy family are recorded as "argent, three lions rampant sinople, etc."
Despite the fact that sinople signified a shade of red in early heraldry, the lions in this 15th century manuscript are clearly green, although rather faded.
The fugitive nature of the green pigments of that day may have had some influence on the low use of that colour in early heraldry.
[5] The only green shown in the arms of the states of the Holy Roman Empire in the Quaternion Eagle by Hans Burgkmair (c. 1510) are the crancelin of Saxony and the Zirbelnuss of Augsburg.
