Nano Nagle, the foundress of the Presentation Sisters, had the Nagle Coat of Arms. It has an escutcheon or shield-shpaed surface in heraldry gold denoting generosity and elevetion of mind. In its center is a horizontal bar or fess, which is a military belt or girdle of honor and signifies, that the bearer must always be in readiness to undergo the business of the public weal. It is azure or blue signifying loyalty anf truth. On the fess are three diamonds in gold. Above the escutcheonis a nightingale. The oak design predominatews. It holds th first place among trees and is said to signify antiquity and strength. Around the escutcheon is a scroll bearing the Nagle motto, NON VOX SED VOTUM, in English, NOT A VOICE BUT A WISH, or more freely translated "NOT WORDS BUT DEEDS".
They Presentation Sisters adopted the Nagle Coat of Arms with some modifications. The nightingale was replaced by a cross and effulgence that symbolize faith and strength as found on the ring worn by th Presentation Sisters.
BCC has adopted the Presentation crest with the motto, Monstra Te Esse Matrem or Show You Are a Mother.
