Giotto, The Storm on the Sea of Galilee ("The Navicella")

St. Peter's Basilica, Rome
Created late 13th or early 14th century for the old St. Peter's Basilica
Almost entirely destroyed during construction of the present building
Re-installed with only a few pieces from the original, 1675

On the right Jesus lifts up St. Peter, who had briefly walked on the water but then took fright and started to sink (Matthew 14:22-32). The small figure in the right corner is Cardinal Jacopo Stefaneschi, who commissioned the mosaic. In the left corner a fisherman on the shore casts his rod into the sea, a reminder that Peter, the apostles, and successors such as the Cardinal were to be "fishers of men" (Matthew 4:19).
