Adjoining the church is Saint Clare's nunnery and it was annexed during the years 1545-1547. In 1545 three noble sisters, together with some devout women founded a convent of Poor Clares and were assigned the adjoining church of the Saints Cosma and Damiano's Church. Owing to the 1866 Laws the western wing of the building was confiscated: there was an elementary school for about a century, in 1958 it was demolished and the central Post Office was built. Some years agothe nuns bought the first floor of this building, thanks to the believers' offerings and some other contributions. The Clares of this convent, besides taking part in the religious rites in the Church with their chants, have helped in the birth and revival of other nunneries in Sicily and Sardinia. Moreover, they made crafts and sweets, ceroplastics and enamelled objects. Nowadays they make silk holy paraments, embroidered with gold and silver threads, or embellished with gems and pieces of coral; they also prepare hosts for several churches.
Works
The interior, organically arranged with its various elements, is embellished by the stuccoes made by Francesco Guastalla and Vincenzo Perez in 1722, and by those realized by Gabriele Messina in 1757. Inside the church there are also:
By the sides of the apse there are two stucco statues, sustained by cloud-shaped brackets: one represents Justice, the other Charity or Piety. They were realized in 1722 by Giacomo Serpotta on behalf of Saint Clara's nunnery and are beautiful, delicate, and full of sensual glamour. Justice, the fundamental virtue regulating human relations, is represented by a female figure with a quietly severe face; on the right hand she holds steelyard balance and on the left hand, on the contrary, she waves a sword, the symbol of the inflexible, but right. justice. Charity, instead, represents a young bride in a quiet contemplation, holding her child in her lap, crying because he wants the mother's milk. According to some experts, she smiles for piety and, instead of being sad about the son's weeping, she is nearly glad for his pressing pangs of hunger and loiters a little, instead of satisfying him. The loving and patient expression of Charity comes up by the side of the quiet but severe attitude of Justice. In this way, Serpotta wished to represent better the feelings of love, piety and justice.
