Saints celebrating feast days today include, but are not limited to, Saint Agatha (patron saint of nurses, wet nurses, and bell founders, invoked against breast disease, earthquakes, sterility, eruptions of Mount Etna, and fire), Saint Agatha (a different one who died around 1024), Saint Avitus of Vienne, Saint Bertoul or Bertulf, Saint Indractus and Dominica, Saint Vodalus or Voel, Saint Adelaide of Bellich, The Martyrs of Japan, Saint Peter Baptist, and Saint Leo Karasuma.
Saint Agatha's probably fictitious legend (the author of the Saint Report is not editorializing here--this is the opinion of Catholic scholars) was grisly enough to have assured her a permanent Sainthood regardless of the evidence.
In the story, the beautiful and wealthy virgin Agatha, who from earliest
childhood had dedicated her life to God, was pursued by a powerful
man who threatened to expose her Christianity if she didn't submit.
In iconography, Saint Agatha is often shown carrying her breasts on a platter, though later artists thought the breasts to be either bells or loaves of bread, leading to the custom of blessing bread on Saint Agatha's feast day and her patronage of bell makers. Other artists depict her with the implements of her torture, i.e. pincers, etc.
