There are so many thousands of images of the Madonna all over Venice, both inside churches and museums, and out on the streets in carvings and shrines. Here are a few of my favorites that can be found inside various churches.
This gorgeous and elegant 13th century relief is high up on a wall of the church of San Francesco della Vigna. A marble Veneto-Byzantine relief with traces of gold, it's one of many beautiful works of art in this church.
This next one can be found in the church of San Pantalon, in a niche on the wall of the Capella del Santo Chiodo. This chapel houses one of Venice's most-revered relics, a sacred nail used in the Crucifixion. Also 13th century, this statue of the Madonna and Child is alabaster with traces of decoration added a few centuries later. Wonderful crowns on them both! More about San Pantalon coming soon (it's a strange and fascinating church).
These next two can both be admired in San Giacomo dall'Orio.
The first one is also 13th century, an image in Greek marble of the Virgin Orante. It's tucked away in a niche in the wall behind a large wooden cabinet where the church puts literature for the parishioners; it's easy to miss. I love her and also the bricks surrounding her.
You can't miss the second one though as she's right beside the entrance to the chancel and always has fresh flowers in front of her. She's 14th century, known as "Our Lady of the Annunciation."
