Small 15th-century angel surmounting a holy water font sculpted by Jacopo di Piero Guidi in 1380. The corresponding sculpture group in the Cathedral is a 19th-century copy. The Angel, depicted pouring the holy water, replaced an earlier decoration, as can be seen in the lunette Fabrizio Boschi frescoed for the Cloister of San Marco (Saint Antonino driving sightseers from the Cathedral) in the early 17th century. The holy water font, in a complex late-Gothic style, is the work of Jacopo di Piero Guidi (1380), the sculptor who also contributed to the Porta della Mandorla in Santa Maria del Fiore. The Angel holding an urn, delicate in form and solemn in gesture, was realized a few decades later, in the Quattrocento; some scholars detect the hand of Urbano di Pietro da Cortona (1426-1504), who was a pupil of Donatello’s in Padua, but active mainly in Siena.
