The Villa of the Mysteries (Villa dei Misteri) is a well-preserved suburban Roman villa on the outskirts of Pompeii, southern Italy, famous for the series of frescos in one room, which are usually thought to show the initiation of a young woman into a Greco-Roman mystery cult. These are now probably the best known of the relatively rare survivals of Ancient Roman painting. Like the rest of the Roman city of Pompeii, the villa was buried in the eruption of Mount Vesuvius in 79 and excavated from 1909 onwards (long after much of the main city). It is now a popular part of tourist visits to Pompeii, and forms part of the UNESCO World Heritage Site at Pompeii.
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.
