The problem: Answer a question about this article:
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 eventually oversaw completion of the Gelati Monastery?
****
The answer: Demetrius I of Georgia
