Line drawing of Beatrice's seal by Ludovico Antonio Muratori (1738). The original wax seal is still extant and attached to a grant Beatrice made to the church of San Zeno in Verona in 1073. The script around the seal reads: SIS SEMPER FELIX, COTFREDO CARA BEATRIX (Beatrice, dear to Godfrey, may you always be happy).
