Toros Roslin (, ); –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.

The colophons in Roslin's manuscripts permit scholars to partially reconstruct the world in which he lived in. In these colophons Roslin appears as a chronicler, who preserved facts and events of his time. In his earliest surviving manuscript the Zeytun Gospel of 1256, Roslin signed his name as "Toros surnamed Roslin". Only Armenians of noble origin had a surname in the Middle Ages; however, the surname of Roslin does not figure among the noble Armenian families. Roslin may have been an offspring of one of the marriages common between Armenians and Franks (any person originating in Catholic western Europe) that were frequent among the nobility but occurred among the lower classes as well. Roslin also names his brother Anton and asks the readers to recall the names of his teachers in their prayers. Professor Levon Chookaszian, head of the Chair of UNESCO and Chair of Armenian Art History at Yerevan State University, proposed a more detailed explanation of the appearance of this surname in the Armenian milieu. According to the professor, the surname Roslin originated from Henry Sinclair of the Clan Sinclair, baron of Roslin who accompanied Godfrey of Bouillon in the
