Piazza della Signoria
Two bronze fountains originally destined for Livorno (c. 1629), still in a highly Mannerist style indebted to Flemish Mannerist goldsmith's work for their grotesque masks and shellwork textures, were set up instead in Piazza della SS. Annunziata, Florence. For Giambologna's equestrian statue of Cosimo de' Medici in the Piazza della Signoria, Tacca contributed the bas-relief panels on its base.
