If you look closer at the rosette plate, on the wall of the villa, we can observe that it is similar in shape to the eye of Sainte Lucie, considered to be a lucky charm in Corsica. This is in fact the operculum of a shell called Turbo, which is found on the Mediterranean shores, particularly on Corsican beaches.
The operculum has a side with a spiral design and the other is of pearly orange or greenish colour. This operculum is known as the Eye of Saint Lucie.
In Corsica, the Eye of Saint Lucie can be found in numerous jewellers. It can be simply mounted as a pendant or associated with other elements for its enhancement.
Lucie is called upon to treat eye problems.
By analogy, the Eye of Sainte Lucie wards off the evil spirit, brings luck and happiness, even favouring prosperity when placed near money.
