The apse mosaic of the Gelati Monastery is a rare example of mosaic use in Georgia. Began by king David IV and completed by his son Demetrius I of Georgia, the fragmentary panel depicts Theotokos flanked by two archangels. The use of mosaic in Gelati attests to some Byzantine influence in the country and was a demonstration of the imperial ambition of the Bagrationids. The mosaic covered church could compete in magnificence with the churches of Constantinople. Gelati is one of few mosaic creations which survived in Georgia but fragments prove that the early churches of Pitsunda and Tsromi were also decorated with mosaic as well as other, lesser known sites. The destroyed 6th century mosaic floors in the Pitsunda Cathedral have been inspired by Roman prototypes. In Tsromi the tesserae are still visible on the walls of the 7th-century church but only faint lines hint at the original scheme. Its central figure was Christ standing and displaying a scroll with Georgian text.
Who started construction on the Gelati Monastery?
king David IV

Examining the influence of humanism on scholars in medicine, mathematics, astronomy and physics may suggest that humanism and universities were a strong impetus for the scientific revolution. Although the connection between humanism and the scientific discovery may very well have begun within the confines of the university, the connection has been commonly perceived as having been severed by the changing nature of science during the scientific revolution. Historians such as Richard S. Westfall have argued that the overt traditionalism of universities inhibited attempts to re-conceptualize nature and knowledge and caused an indelible tension between universities and scientists. This resistance to changes in science may have been a significant factor in driving many scientists away from the university and toward private benefactors, usually in princely courts, and associations with newly forming scientific societies.
Which historian argues that traditionalism in a university system hindered attempts to form new views on knowledge and nature?
Richard S. Westfall
