Pre-Christian basilica with a regular layout, the central nave paved with a magnificent mosaic which can still be seen. It dates from the 6th century A.D., when the Byzantine army of Justinian (the Eastern Roman Emperor who aspired to rebuild the Western Roman Empire) had conquered the Balearic Islands.
It faces from east to west, and on the northern side retains a small hemispherical baptismal font built in stone and mortar, with a waterproof lining.
There are three separate sections: The rectangular apse with the base of an altar, surrounded by bunches of grapes, the central motif being a classical wine bowl and two peacocks. The grapes represent life, while the peacocks facing one another represent the resurrection. Between the nave and the head, two lions face a palm tree. They have been interpreted as a reference to Jewish tradition, which was particularly important at that time in Maó. The lions represent the power of death, while the palm is the tree of life. The nave for the congregation reveals geometric figures and depictions of birds, in a clearreference to Paradise.
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.
