Fabris was also the Supreme Knight of the Order of the Seven Hearts, a chivalrous order of which we do not yet know much today. The order's insignia, consisting of seven hearts arranged in a cross pattern surmounted by a phoenix bird, are visible on the left breast of Fabris' only extant portrait (see illustration). The wording "Supreme Knight of the Order of the Seven Hearts" is coupled with the author's name in all editions of Fabris' work, indicating that it must have been a point of importance.
