St Francis didn't actually write this prayer. It is much more recent. According to Daniel Horan it was composed by an anonymous French writer about 100 years ago. The prayer does reflect both the way St Francis lived his life and the Franciscan spiritual tradition.
Today is his day, so here is a version of the 'Prayer of St Francis' with music and photographic images of the natural world.
