The custom spans both centuries and cultures, with roots going back as far as the Ancient Greeks. In early Greece, May was dedicated to Artemis, the goddess of fecundity.
During this period, the tradition of Tricesimum, or “Thirty-Day Devotion to Mary,” came into being. Also called, “Lady Month,” the event was held from August 15-September 14 and is still observed in some areas.
The idea of a month dedicated specifically to Mary can be traced back to baroque times. Although it wasn’t always held during May, Mary Month included thirty daily spiritual exercises honoring Mary.
It was in this era that Mary’s Month and May were combined, making May the Month of Mary with special devotions organized on each day throughout the month. This custom became especially widespread during the nineteenth century and remains in practice until today.
It’s common for parishes have a daily recitation of the Rosary during May, and many erect a special May altar with a statue or picture of Mary as a reminder of Mary’s month. Additionally, it’s a long-standing tradition to crown the statue of Mary during May – a custom known as May Crowning. Often, the crown is made of beautiful blossoms representing Mary’s beauty and virtue. It’s also a reminder to the faithful to strive to imitate our Blessed Mother’s virtue in our own lives. May Crowning, in some areas, is a huge celebration and is usually done outside of Mass, although Mass may be celebrated before or after the actual crowning.
But May altars and crownings aren’t just “church” things. We can and should be doing the same in our homes. When we echo the customs and traditions of the Church in our homes – our domestic churches – we participate more fully in the life of the Church.
