Mosaics are beautiful, though most fall into two categories: religious art, and Millard Sheets's work. There are some exceptions, and I'll try to find them. Every Monday. . . unless I forget.
This picture is found on the facade of St. Lawrence Martyr School in Redondo Beach. The parish dates back to 1956, I think, and the church was dedicated in 1957. The school followed shortly after, and I believe this mosaic was part of the original construction. It shows St. Lawrence, a third century martyr who died during the persecution of Roman Emperor Valerian, distributing alms to the poor.
