Victory at Lepanto!
"The Pope was in his chapel before day or battle broke,
(Don John of Austria is hidden in the smoke.)
The hidden room in man's house where God sits all the year,
The secret window whence the world looks small and very dear."
– from Chesterton's Lepanto which can be read here.
This fresco of the Dominican Pope St Pius V praying the Rosary during the Battle of Lepanto is in his room in Santa Sabina, Rome.
Through the intercession of Our Lady, victory was won by the Christian forces today 7 October in 1571 over the oppression of the Muslim Turks.
