Loggia Mosaics Self-researched

Mosaics decorating the upper loggia of the basilica's facade. The upper register shows Christ Blessing flanked by symbols of the four Evangelists; the lower register narrates the legend of the miraculous August snowfall that prompted the founding of the basilica by Pope Liberius. These 13th-century mosaics are now partially hidden behind the 18th-century facade by Ferdinando Fuga.
