About Our Lady of Good Counsel
Our Lady / Mother of Good Counsel is a Marian devotion that started in the 15th century.The title ( in Latin, Mater boni consilii) was originally given to a small (40cm X 45cm) image of Mary and Jesus as a child, which is now in a 13th century Augustinian church at Genazzano, near Rome, in Italy.
Oral tradition is that the fresco (painting) was on a church wall in Scutari, Albania. During a conflict with Turkey1467, the sanctuary of the church was mostly destroyed, and the wall where the fresco had been was suddenly blank. The same year in Genazanno, during Vespers on the feast of Saint Mark, people suddenly heard beautiful music coming from a cloud above a church. The cloud descended on the church and hovered above the wall of an unfinished chapel. Church bells throughout the town started ringing. When the cloud eventually disappeared, the fresco of was on the chapel wall: it had escape the Turkish invasion and migrated to Italy. Following this, the fresco was named "Our Lady of Good Counsel" - after the church where it had come to rest.
Many miracles are believed to have occurred in the portrait’s presence.
