Thanks to Fuse for the reminder that today, September 30, honors St. Jerome. Born in 347 CE in Stridon (modern Northeast Italy), Jerome is the patron saint of libraries and librarians, archivists, translators, and encyclopedists.

According to Wikipedia, he was a bookish sort and collected both pagan and Christian tomes. His scholarly work includes important translations of the Bible and Biblical commentary.

Artists have depicted St. Jerome as a half-clad hermit with cross, skull, and Bible. He is frequently accompanied by a lion from whose paw he is said to have withdrawn a thorn. That's a Caravaggio above.
