A pupil of Andre Grabar, Tania Velmans has worked for over thirty years on the art of the Byzantine empire and its wider diffusion throughout the neighbouring Slavic lands. This new volume brings together seven important studies on the art and intellectual world of Byzantium. A long introductory survey of the representation of space in Byzantine art is followed by papers on the expression of time, on Hesychasm and its influence on art, and on Byzantine portraits. A paper on the iconography of the painted churches of Moldavia is followed by a reflection on the spread of Constantinopolitan artistic models to the margins of the Byzantine world. French text.
