Ex-voti are usually placed in a church, affixed in a chapel or roadside shrine, like the one portrayed, where the worshiper seeks grace or gives thanks for a wish granted.
An ex-voto is a votive offering to a saint or divinity. It is given in fulfillment of a vow–the Latin term is short for ex voto suscepto, “from the vow made”–or in gratitude or devotion.
As such these may include plaques, marble tablets or handwritten signs with texts explaining the miracle attributed to the helper, or symbols such as a painted or modeled reproduction of a miraculously healed body part, or a directly related item, like a crutch given by a formerly lame person.I’ve seen ex-voti around town include paintings of saved dogs, silver heart shapes, model boats, war medals and even football shirts given by players and supporters of a winning local soccer team..The mosaic on the busy corner of Rome’s Via Gramsci and Viale Buozzi here, is in itself an ex-voto expressing gratitude for rescue from a car wreck. Amen.
