At either end of the portico, in front of the church of Santissima Annunziata, is the profile of a black head set against a white background. This is the coat of arms of the Pucci family, once one of the major clans in Florence, who were patrons of the church.
The white band, which is tied around the head, bears three letter Ts, which stand for the family motto Tempore tempora tempera (Time is a great healer). An earlier motto had been Candida Praecordia (White at heart).
The headband had originally been decorated with three hammers, symbolising, perhaps, an ancestor's membership of the carpenters' guild.
The Pucci family pile, which is one of the largest palaces in Florence, lies near the church.
