The Collegiate Church of St. Bartholomew was built in coal sandstone, starting in the late 11th century (the chancel) and lasting until the late 12th century (the massive westwork, with its twin towers which were reconstructed in 1876). It underwent, like most ancient religious buildings, modifications through the centuries. Nevertheless, the Meuse Romanesque—Ottonian architecture character of its architecture remained deeply rooted. The 18th century saw the addition of two more aisles, the opening of a neoclassical portal in the walls of the westwork, and the French Baroque redecoration of the interior. The interior of the western section has recently been restored back to the original style.
The church contains numerous works of art, among which may be mentioned The Glorification of the Holy Cross, a tableau of the local painter Bertholet Flemalle (1614-1675); The Crucifixion, from another local artist, Englebert Fisen (1655-1733); and a statue of St. Roch by Renier Panhay de Rendeux.
St. Bartholomew is the site of one of the most known examples of ecclesiastical Mosan art, a baptismal font attributed to the goldsmith Renier de Huy. It was commissioned at the beginning of the 12th century (1107-1108) by the Abbot Hellin for the Church of Notre-Dame-aux-Fonts, now destroyed, where local baptisms traditionally were administered.
The font was installed in St. Bartholomew Church in 1804, after having been spared from the occupying forces of the French Revolutionary Army.
This work heralds a resurgence of Greek influences on Western art. The brass tank, resting on ten (originally twelve) ox figures, presents five scenes: the Baptism of Jesus in the Jordan, the preaching of St. John the Baptist, the baptism of the catechumens, the baptism of the Centurion Cornelius, and the baptism of the philosopher Craton.
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.
