Casmenae or Kasmenai was an ancient Greek colony located on the Hyblaean Mountains, founded in 644 BC by the Syracusans at a strategic position for the control of central Sicily. It was also intended as a military forward-position on the Via Selinuntina road that connected Syracuse to Akragas (modern-day Agrigento) - also on that road were Gela and Akrillai to Casmene's west and Akrai to its east. Destroyed by the Romans in 212 BC, Casmene was abandoned during the 3rd century BC and never inhabited again.
The site was discovered by the Sicilian archeologist Paolo Orsi during the first half of the 20th century, after he had identified the most probably site at Monte Casale in Buscemi at 830m above sea level, on an extinct volcano near Monte Lauro, 7 km from Giarratana and 12 km from Palazzolo Acreide. Remains of the defensive walls, long 3.400m, are still visible with the base of one of the temples and some dwellings.
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.
