The Life of Mashtots is a hagiography of Saint Mesrop Mashtots, who, with Catholicos Sahak and King Vramshapuh, created the Armenian, Georgian and Aghuanian alphabets to advance the Church's ministry in these kingdoms. With the assistance of Greek and Syriac clerics who helped design and refine the letters, they laid the foundation for schools, Scripture translations and enduring historical legacies. Written by Mashtots' youngest disciple, Koriun, it is among the first works composed in the Armenian language and script.
