Vatican, Vatican Library is at http://en.wikipedia.org/wiki/Vatican_Library
Founded by Pope Nicholas V in the 15th century, the Vatican Library possesses, amongst other things, 4500 Greek manuscripts. Treasure and library: sizable collection of objects of goldsmith´s work (enamels), textiles, illustrated manuscripts, for example Joshua Roll which consists of a parchment about 10,5 m. long and 31 cm high on which the exploits of Joshua are set out in uninterrupted sequence. The date of the work is the subject of controversy (5th century? 10th century?). Profoundly penetrated by Hellenistic traditions, the work perhaps evinces the antiquising taste prevalent at Constantinople in the tenth century http://en.wikipedia.org/wiki/Joshua_Roll.
