The theme of this original study was a unique scientific material: a collection of illustrated manuscripts of the 11th century, executed by Armenian masters and now carefully preserved in Matenadaran - the Research Institute of Ancient Manuscripts named after Mesrop Mashtots (Yerevan). The study of this material allowed the author to create an integral picture of the 11th century Armenian book miniature. To objectify this picture, the most famous Armenian manuscript monuments of the 11th century, stored in the libraries of Jerusalem and Venice, were also examined. Much attention in the book is paid to issues of typological and stylistic connections between various schools in Europe and the East.
