The arms (above) of the Most Rev. Stefano Manetti, installed April 13 as the Bishop of Montepulciano-Chiusi-Pienza, Italy. The wavy line is a reference to the waters of baptism; the star to Our Lady and the scallop shell to the pilgrim journey of faith. Very nice!
Looking at the drawing-style I think the designer is the Italian heraldist Giuseppe Quattrochiocchi. Congratulations for him!
