Sybaris was an important city of Magna Graecia. The city was founded in 720 BC by Achaean and Troezenian settlers. Sybaris amassed great wealth thanks to its fertile land and busy port. Its inhabitants became famous among the Greeks for their hedonism, feasts, and excesses, to the extent that 'sybarite' and 'sybaritic' have become bywords for opulence, luxury and outrageous pleasure-seeking.
In 510/09 BC the city was subjugated by its neighbor Kroton and its population driven out. Sybaris became a dependent ally of Kroton, but Kroton again besieged the city in 476/5 BC, probably resulting in another victory for Kroton. Two attempts to reoccupy the city failed around 452/1 BC and 446/5 BC when the remaining Sybarites were again expelled by the Krotoniates. After a call for help the Sybarites reoccupied their city later in 446/5 BC with the assistance of new settlers from Athens and other cities in the Peloponnese. This coexistence did not last long: the Sybarites got into a conflict with the new colonists and were ousted for the last time in the summer of 445 BC. In sum, the city saw a total of five periods of occupation separated by expulsion. The new settlers then proceeded to found the city of Thurii in 444/3 BC, a new colony which was built partially on top of the site of Sybaris. The surviving Sybarites founded Sybaris on the Traeis.
The ruins of Sybaris and Thurii became forgotten as they were buried by sediment from the Crati river over time. The ruins were rediscovered and excavated in the 1960s by Donald Freeman Brown. Today they can be found southeast of Sibari, a frazione in the comune of Cassano allo Ionio.
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.
