The so-called Temple of Demeter (the remains of which are located below of the church of San Biagio) can be dated between 480 and 470 BCE. This temple offers an interesting example of distylous building in antis, i.e.without an outer colonnade. It has a simple cella preceded by a pronaos (ante-room) with two columns.
Still preserved from the original structure are the base (30 by 13 m approx and partly visible), the outer cella walls and the wall between the cella and the pronaos. These remaing parts have been incorporated in the medieval church dedicated to St. Biagio. The beautiful water spouts in the shape of lion’s heads from this building can still be seen in the Regional Archaeological Museum of Agrigento in the room dedicated to architectural sculptures.
The Temple of Demeter in the classical period was part of a temenos, a sacred enclosure that included other adjacent structures, such as two small round altars with a central bothros or holy well. Inside, archaeologists found kernoi (ritual vessels linked to the cult of Persephone) and the remains of busts that must have represented Demeter.
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.
