Why is St Agatha the Patron Saint of Bellfounders?

February 5th is the Feast Day of St Agatha, the third century Sicilian saint.  

According to legend, St Agatha was tortured by having her breasts pulled off with a pair of tongs. This led to her later becoming the patron saint of bellfounders, on account of the similarity in shape of breasts and bells. 

In images of St Agatha, she holds a dish sporting her severed breasts, as we can see on the facade of the ancient church of Sant' Agata dei Goti.
