Consecrated in the 11th century, the San Giovanni del Toro church was restored in 1715 after damage caused by an earthquake, and it was restored again in the 1990s. The church is named for John the Apostle and for 'Il Toro', the former name of the old aristocratic quarter in which it was built. It is especially noted for its pulpit, dating from around the 13th century.
The pulpit is notable for its mosaics, the decorative patterns of which inspired the interlocking patterns used by M.C. Escher, who spent time in Ravello in the 1920s and studied the church and the pulpit; Ravello was one of his favorite places. One mosaic is of Jonahe merging from the whale. An eagle supports the reading desk, and it holds a book opened to the first sentence of the Gospel of John. The 'beautiful' pulpit, which dates from the time of Roger I of Sicily, also contains Oriental pottery and Arabic script, and the steps up to it contain well-preserved frescoes with scenes from the life of Christ. There is a side chapel with a stucco figure of Saint Catherine and her wheel.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
