 "Azure, three fleurs-de-lys or", anciently "Azure, semée-de-lys or"), often violates this rule when the field is of a colour.The coat of arms appearing on the famous tapestry of "The Lady and the Unicorn" (Paris, c.1500) was attributed until now by specialistes to the older branch and to the chief of the family Le Viste, Jean IV Le Viste, but it blatantly breaks the rules of French Heraldry.A new study of the tapestry suggests the probability of the intervention of a descendant of the younger branch, Antoine II Le Viste, as a sponsor of the tapestry, and indicates that the incorrect superposition of colours could have been a mere difference.
