Abstract
In the context of the flagrant mistakes that are encountered in ecclesiastical painting and the lack of basic knowledge in this field, this study comes to present how Hermeneia has evolved throughout history. Starting from the Byzantine period, passing through the post-Byzantine period and reaching to the present day, Hermeneia and her predecessors, manuscripts and sketchbooks, aimed to help and maintain a canonical-artistic-ecclesial unity throughout the Orthodox Christian area. Another aspect of the article presents some ways of approaching Hermeneia from various points of view: technical, iconographic-illustrative, compositional, academic and theological. Throughout history, Hermeneia has been synthesized and structured in such a way as to provide a maximum of information but its volume should not be difficult to use by iconographers.
