St Julian of Norwich

Her feast day is today, May 13th, in some local calendars.  She was never formally canonized and is sometimes only Blessed Julian.  The good old Catholic Encyclopædia tells what is known of her here.

Her "Revelation of Divine Love" as it's called is on the web somewhere in its entirety.  (I've lost the link and I'm being summoned right at the moment by She Who Must Be Obeyed.  Google will find it for you no doubt.  Or maybe I will later.)

Addendum: And so I did.  It's here.  And there are a couple other versions on line, too.  But this should do to start.
