May Devotions to the Blessed Virgin Mary refers to special Marian devotions held in the Catholic Church during the month of May honoring the Virgin Mary as "the Queen of May". These services may take place inside or outside. A "May Crowning" is a traditional Roman Catholic ritual that occurs in the month of May.
A number of traditions link the month of May to Mary. Alfonso X of Castile in the 13th century wrote in his Cantigas de Santa Maria about the special honoring of Mary during specific dates in May. Eventually, the entire month was filled with special observances and devotions to Mary.
The origin of the conventional May devotion is still relatively unknown. Herbert Thurston identifies the seventeenth century as the earliest instance of the adoption of the custom of consecrating the month of May to the Blessed Virgin by special observances. It is certain that this form of Marian devotion began in Italy. Around 1739, witnesses speak of a particular form of Marian devotion in May in Grezzano near Verona. In 1747 the Archbishop of Genoa recommended the May devotion as a devotion for the home. Specific prayers for them were promulgated in Rome in 1838.
According to Frederick Holweck, the May devotion in its present form originated at Rome where Father Latomia of the Roman College of the Society of Jesus, to counteract infidelity and immorality among the students, made a vow at the end of the eighteenth century to devote the month of May to Mary. From Rome the practice spread to the other Jesuit colleges and thence to nearly every Catholic church of the Latin rite. In Rome by 1813, May devotions were held in as many as twenty churches. From Italy, May devotions soon spread to France. In Belgium, the May devotions, at least as a private devotion, were already known by 1803. The tradition of honoring Mary in a month-long May devotion spread eventually around the Roman Catholic world in the 19th century together with a month-long devotion to Jesus in June and the Rosary in October.
In his 1965 encyclical, Mense Maio, Pope Paul VI identified the month of May as an opportune time to incorporate special prayers for peace into traditional May devotions.
There is no firm structure as to the content of a May devotion. It usually includes the singing of Marian anthems, readings from scriptures, and a sermon. Although prayers likely include the recitation of the Hail Mary, the rosary itself is not usually a part of this particular devotion. Catholics offer Mary special honor in May: pilgrimages, visits to churches dedicated to her, little sacrifices in her honor, periods of study and well-finished work offered up to her, and a more attentive recitation of the rosary.
