This is a large screen that separates the nave of the church from the choir section of the eastern end in the church. It is from the 14th century, and found in Florence and Venice. It is made of iron and the design has many quatrefoils tied together. A quatrefoil is a four -leaf clover design. This metal work is very pretty, and we do not see much of it today, which is a shame because it is very beautiful metal work.
