The Church, since 1684, celebrates today the Feast of the Holy Name of Mary. This feast commerates the victory at the Battle of Vienna in 1683 during which the Polish-Lithuanian Commonwealth (Holy League) liberated the besieged Vienna on the fields of Kahlenberg. For the history buffs, this battle is noted as the largest calvary charge in history (20,000 men).
The Roman Martyrology speaks about this feast in the following terms:
The Holy Name of the Blessed Virgin Mary, a day on which the inexpressible love of the Mother of God for her Holy Child is recalled, and the eyes of the faithful are directed to the figure of the Mother of the Redeemer, for them to invoke with devotion.
