hey i found an old statue and tried to identify the font and it looks very similar to bronzino.
http://www.myfonts.com/fonts/gatf/bronzino/
but bronzino was designed in 2010 and the statue is 50-60 years old, so i search for the "real" font... :D

similar font to "Bronzino" but older
If it's on a statue and it's 50-60 years old, it's hand-cut and not a font.
That being said, T.M. Cleland's Della Robbia (1902) may have been the inspiration for the inscription you saw.
Plus, if you read the descriptive copy, the font has its roots in the Arts and Crafts movement, which predates your statue by forty or more years...
