Toros Roslin was the most prominent Armenian manuscript illuminator in the High Middle Ages. Roslin introduced a wider range of narrative in his iconography based on his knowledge of western European art while continuing the conventions established by his predecessors. Roslin enriched Armenian manuscript painting by introducing new artistic themes such as the Incredulity of Thomas and Passage of the Red Sea.

In addition he revived the genre of royal portraits; the first Cilician royal portraits having been found in his manuscripts. His style is characterized by a delicacy of color; classical treatment of figures and their garments; an elegance of line; and an innovative iconography. Pictures From History
