The Villa Romana del Casale is a large and elaborate Roman villa or palace located about 3 km from Piazza Armerina. Excavations have revealed one of the richest, largest, and varied collections of Roman mosaics in the world, for which the site has been designated as a UNESCO World Heritage Site.
The mosaic and opus sectile floors cover some 3,500 sq metres and are almost unique in their excellent state of preservation due to the landslide and floods that covered the remains.
Although less well-known, an extraordinary collection of frescoes covered not only the interior rooms, but also the exterior walls.
The visible remains of the villa were constructed in the first quarter of the 4th century AD on the remains of an older villa rustica, which are the pars dominica, or master’s residence, of a large latifundium or agricultural estate.
The owner's identity has long been discussed and many different hypotheses have been formulated. Some features such as the Tetrarchic military insignia and the probable Tetrarchic date of the mosaics have led scholars to suggest an imperial owner such as Maximian. However, scholars now believe that the villa was the centre of the great estate of a high-level senatorial aristocrat.
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.
