Vision of the Blessed Virgin by Isaiah and David
The introductory mural on the south side of the church depicts "Prophets Foretelling the Birth of the Messiah from Mary." In this fresco, Mary is presented in a mandorla, holding the Christ Child, who is crowned. Below the figure to Mary's right is King David, from whose line Mary proceeded. On Mary's left is the prophet Isaiah holding a scroll proclaiming, "Behold a virgin shall conceive and bear a son."
Mary's Immaculate Conception is hinted at. The panel shows her standing on a crescent moon, wearing a crown, and twelve stars adorn her halo.
