On March 25, 1370, a ship coming from Spain was traveling towards Italy when it was seized by a terrible storm that put the lives of the crew and passengers at risk. The captain, in a last attempt to save the crew of the ship, ordered the sailors to cast into the sea the ship's cargo. This was done but without any aid to the sailors. There was a large crate within the ship’s cargo - this was cast into the sea last of all the cargo. Suddenly, upon the crate entering the water, the storm ceased. The ship, attempting to regain the cargo, followed the crate for some time. Unable to retrieve it, the ship returned to its original route. The crate, however ran aground on the beach at the foot of the hill of Bonaria. Many people were on the beach when the crate arrived and rushed to see what it was. They tried to open it, but no one succeeded. They tried to lift it, but every attempt was in vain - the box was too heavy. Suddenly a child cried out: “Call for one of the Mercedarian Friars!” The friars came in haste, and without any difficulty, raised the heavy crate and carried it into their church. In silence and piety, the friars opened the crate, and along with everyone there, saw the contents. In that crate was a marvelous statue of the Blessed Virgin Mary and Child in her arms and, in her right hand, a lighted candle.
Etymology
When the Catalans by name of the King of Aragon and Count of Barcelona conquered Cagliari, Sardinia from the Pisans in 1324, they established their headquarters on top of a hill that overlooked the city. The hill was known to them as Bon Ayre, as it was free of the foul smell prevalent in the old city, which is adjacent to swampland. During the siege of Cagliari, the Catalans built a sanctuary to the Virgin Mary on top of the hill. In 1335, King Alfonso the Gentle donated the church to the Mercedarians, who built an abbey that stands to this day. In the years after that, a story circulated, claiming that a statue of the Virgin Mary was retrieved from the sea after it miraculously helped to calm a storm in the Mediterranean Sea. The statue was placed in the abbey. Two centuries later, Spanish sailors, especially Andalusians, venerated this image and frequently invoked the "Fair Winds" to aid them in their navigation and prevent shipwrecks. A sanctuary to the Virgin of Buen Aire would be later erected in Seville. The capital of Argentina, Buenos Aires, was named by its founders the captain Pedro de Mendoza: Santa María del Buen Aire, a name chosen by the chaplain of Mendoza's expedition, a devotee of the Virgin of Buen Aire. Mendoza’s settlement soon came under attack by indigenous peoples, and was abandoned in 1541.
Queen Patroness
Devotion to Our Lady of Bonaria spread quickly over the island, and the Blessed Virgin Mary under this title has been named the patroness of Sardinia, then later became a patroness for Buenos Aires, Argentina along with the Holy Trinity.
