18th Century Italian 'Florence Fragment' with a Chalcedony Rosette
By Interi
Located in Dublin, Dalkey
17th century Italian fragment with a chalcedony rosette. It has antique hand-written Italian inscriptions on the base. The chalcedony mineral mimics the color and texture of the distressed wood fragment.
This fragment is from a church in Florence. It was found and saved from the historic Florence Flood of 1966. This was one of the worst floods recorded since the Renaissance and drew thousands of volunteers from all over the world to help save the city known for its precious history, artwork, artifacts, and rare books. The volunteers were called "the mud angels" because of the mud and silt left everything from the damage of the flood. There is still the original paint and silt left on the piece to uphold the integrity, craftmanship, and history of sculptural fragment.
