San Giuseppe dei Teatini is considered one of the most outstanding examples of the Sicilian Baroque in Palermo.
The church was built at the beginning of the 17th century by Giacomo Besio, a Genoese member of the Theatines order. It has a majestic though simple façade. In the centre niche is housed a statue of San Gaetano, founder of the Theatines order. Another striking feature is the large dome with a blue and yellow majolica covering. The tambour decorated with double columns, and was designed by Giuseppe Mariani. The belfry tower was designed by Paolo Amato.
The interior has a Latin cross plan with a nave and two aisles, divided by marble columns of variable height. The inner decoration is an overwhelming parade of Baroque art, with stuccoes by Paolo Corso and Giuseppe Serpotta. Great frescoes can be seen in the nave, in the vault of the transept: these were painted by Filippo Tancredi, Guglielmo Borremans and Giuseppe Velasquez. The frescoes were severely damaged during World War II, but have been accurately restored. The most important piece of art is however a wood crucifix by Fra' Umile of Petralia.
The crypt houses remains of a former church, dedicated to Madonna of Providence.
References:The Arch of Constantine is situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge in 312. Dedicated in 315, it is the largest Roman triumphal arch. The arch spans the Via triumphalis, the way taken by the emperors when they entered the city in triumph.
Though dedicated to Constantine, much of the decorative material incorporated earlier work from the time of the emperors Trajan (98-117), Hadrian (117-138) and Marcus Aurelius (161-180), and is thus a collage. The last of the existing triumphal arches in Rome, it is also the only one to make extensive use of spolia, reusing several major reliefs from 2nd century imperial monuments, which give a striking and famous stylistic contrast to the sculpture newly created for the arch.
The arch is 21 m high, 25.9 m wide and 7.4 m deep. Above the archways is placed the attic, composed of brickwork reveted (faced) with marble. A staircase within the arch is entered from a door at some height from the ground, on the west side, facing the Palatine Hill. The general design with a main part structured by detached columns and an attic with the main inscription above is modelled after the example of the Arch of Septimius Severus on the Roman Forum.
