Iconography, as a branch of art history, studies the identification, description, and the interpretation of the content of images: the subjects depicted, the particular compositions and details used to do so, and other elements that are distinct from artistic style. The word iconography comes from the Greek εἰκών ("image") and γράφειν ("to write"). A secondary meaning (based on a non-standard translation of the Greek and Russian equivalent terms) is the production of religious images, called "icons", in the Byzantine and Orthodox Christian tradition; see Icon. In art history, "an iconography" may also mean a particular depiction of a subject in terms of the content of the image, such as the number of figures used, their placing and gestures. The term is also used in many academic fields ot
