On this day we celebrate the feast of St. Clare.
For some beautiful Latin, click here. It's the Bull of Canonization of St. Clare of Assisi by Pope Alexander IV, "Given at Anagni, the sixth day before the Calends of October, in the first year of our pontificate." (1255.)
"CLARA CLARIS PRAECLARA meritis, magnae in caelo claritate gloriae, ac in terra splendore miraculorum sublimium clare claret."
The English translation is beside the Latin, but it's hardly needed. The Pope's use of alliteration makes his meaning clear.
