Toros Roslin (Armenian: Թորոս Ռոսլին, Armenian pronunciation: [tʰɔɹɔs rɔslin]); c. 1210–1270) 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.The human figures in his illustrations are rendered full of life, representing different emotional states. Roslin's illustrations often occupy the entire surface of the manuscript page and at times only parts of it, in other cases they are incorporated in the texts in harmony with the ensemble of the decoration.
