In the sixth century, under the emperor Justinian, occurred the birth of an extraordinary and innovative architecture that now we call “Byzantine architecture” and that lasted for centuries: from Byzantium to Constantinople, from the greek and cretan Mediterranean to the Balkan region, true heir of Byzantium art. This journey through time and space, written by serbian authors V. Kora0 and M. Šuput and introduced by Mauro della Valle, is a synthesis of the architecture born with Justinian, developed in the Slavic world and infl uencing the Ottoman world. An architecture full of amazing colors and patterns but faithful to its original structure: a cultural and artistic commonwealth.
