Sub tuum praesidium confugimus,
Sancta Dei Genetrix.
Nostras deprecationes ne despicias in necessitatibus,
sed a periculis cunctis libera nos semper,
Virgo gloriosa et benedicta.
We fly to thy patronage,
O holy Mother of God;
despise not our petitions in our necessities,
but deliver us always from all dangers,
O glorious and blessed Virgin.
