Today is the feast day of Saint Lawrence the Librarian.
He is said to have been roasted on a grill in the hope that he would reveal the names of the Christians on the list he kept as librarian and archivist of the early church. (Click on image to enlarge it and for information about the engraving itself.)
However, it is more likely that he was beheaded rather than roasted. For a better understanding of the varying accounts of his martyrdom, see "It's not Gruesome - It's Reverence."
