of Europe with a great library in Medicine and other sciences. Many physicians came there for medical and other knowledge. That is why the first High Medical School in the world was soon opened in nearby Salerno which is considered today to have been the earliest Institution of Higher Education in Western Europe. This school found its original base in the Benedictine Abbey of Monte Cassino still in the 9th century and later settled down in Salerno. So, Montecassino and Benedictines played a great role in the progress of medicine and science in the Middle Ages, and with his life and work St. Benedict himself exercised a fundamental influence on the development of European civilization and culture and helped Europe to emerge from the "dark night of history" that followed the fall of the Roman empire. The buildings of the monastery were reconstructed in the 11th century on a scale of great magnificence, artists being brought from Amalfi, Lombardy, and even Constantinople to supervise the various works. The abbey church, rebuilt and decorated with the utmost splendor, was consecrated in 1071 by Pope Alexander II. A detailed account of the abbey at this date exists in the Chronica monasterii Cassinensis by Leo of Ostia and Amatus of Monte Cassino gives us our best source on the early Normans in the south. Abbot Desiderius sent envoys to Constantinople some time after 1066 to hire expert Byzantine mosaicists for the decoration of the rebuilt abbey church. According to chronicler Leo of Ostia the Greek artists decorated the apse, the arch and the vestibule of the basilica. Their work was admired by contemporaries but was totally destroyed in later centuries except two fragments depicting greyhounds (now in the Monte Cassino Museum). "The abbot in his wisdom decided that a great number of young monks in the monastery should be thoroughly initiated in these arts" – says the chronicler about the role of the Greeks in the revival of mosaic art in medieval Italy. Architectural historian Kenneth John Conant believed that Desiderius' rebuilding included pointed arches, and served as a major influence in the nascent development of Gothic architecture. Abbot Hugh of Cluny visited Monte Cassino in 1083, and five years later he began to build the third church at Cluny Abbey, which then included pointed arches and became a major turning point in medieval architecture. An earthquake damaged the Abbey in 1349, and
