УByzantium created a brilliant culture, may be, the most brilliant during the whole Middle Ages, doubtlessly the only one existing in Christian Europe before the XI century. For many years, Constantinople remained the sole grand city of Christian Europe ranking second to none in splendour. Byzantium literature and art exerted a significant impact on peoples around it. The monuments and majestic works of art, remaining after it, show us the whole lustre of byzantine culture. ThatТs why Byzantium held a significant place in the history of Middle Ages and, one must admit it, a merited one.Ф
