Our lady of the snows devotion to Mary under the title of Our Lady of the Snows dates back to 352 A.D. when, according to legend, Mary appeared to a childless, wealthy Roman couple in a dream on a hot summer night. She told them she wanted a church to be built in her honor in Rome. She also told them the site would be covered with a blanket of snow. The same night, she appeared to Pope Liberius in a dream also telling him of her desire. The next morning, Rome awoke to snow on Esquiline Hill even though the weather was extremely warm. The summer snow was proclaimed a miracle and the couple took that as a sign to use their wealth to help build the church. The Basilica of St. Mary Major was built on the site and still stands today as the seat of devotion to Our Lady of the Snows. This vision of mary is one of three hundred and fifty official titles given to mary. Click this for link. Posted by tommy jones of mary visions.
