The cave of Ellinokamara οn the Island of Kasos has been νisited in the course of time by travellers and archaeologists who have provided us with detailed descriptions and sketches both of the interior and of the exterior of the cave. The first sketch we have was made by L. Ross in 1843 while passing through Kasos during his travels in the Aegean archipelago. The entrance wall has been dated to the second half of the 5th century BC, regardless of the marks made by masons that he had recorded. Although we recognize the difficulty in dating the construction we cannot, of course, base ουr assumptions solely οn the manner the wall was built, since similar constructions existed during the Minoan l Mycenaean period and even later.
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.
