Hippana was an ancient town of Sicily, mentioned by Polybius as being taken by assault by the Romans in the First Punic War, 260 BCE. Diodorus, in relating the events of the same campaign, mentions the capture of a town called 'Sittana', for which we should in all probability read 'Hippana'. It sat astride the main road from Panormus (modern Palermo) to Agrigentum (modern Agrigento) upon Monte dei Cavalli.
Some manuscripts of Pliny mention the name of Ipanenses in his list of Sicilian towns, where the older editions have Ichanenses. If this reading be adopted, it in all probability refers to the same place as the Hippana of Polybius; but as the reading Ichanenses is also supported by the authority of Stephanus (who notices Ichana as a town of Sicily), the point must be considered doubtful.
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.
