Epigraphy, inscription, is the study of inscriptions, or epigraphs, as writing; it is the science of identifying graphemes, clarifying their meanings, classifying their uses according to dates and cultural contexts, and drawing conclusions about the writing and the writers. Specifically excluded from epigraphy are the historical significance of an epigraph as a document and the artistic value of a literary composition. A person using the methods of epigraphy is called an epigrapher or epigraphist. For example, the Behistun inscription is an official document of the Achaemenid Empire engraved on native rock at a location in Iran. Epigraphists are responsible for reconstructing, translating, and dating the trilingual inscription and finding any relevant circumstances. It is the work of historians, however, to determine and interpret the events recorded by the inscription as document. Often, epigraphy and history are competences practised by the same person. An epigraph or epigram is any sort of text, from a single grapheme (such as marks on a pot that abbreviate the name of the merchant who shipped commodities in the pot) to a lengthy document (such as a treatise, a work of literature, or a hagiographic inscription). Epigraphy overlaps other competences such as numismatics or palaeography. When compared to books, most inscriptions are short. The media and the forms of the graphemes are diverse: engravings in stone or metal, scratches on rock, impressions in wax, embossing on cast metal, cameo or intaglio on precious stones, painting on ceramic or in fresco. Typically the material is durable, but the durability might be an accident of circumstance, such as the baking of a clay tablet in a conflagration. The study of ideographic inscriptions, that is inscriptions representing an idea or concept, may also be called ideography. The German equivalent Sinnbildforschung was a scientific discipline in the Third Reich, but was later dismissed as being highly ideological. Epigraphic research overlaps with the study of petroglyphs, which deals with specimens of pictographic, ideographic and logographic writing. The study of ancient handwriting, usually in ink, is a separate field, palaeography. Epigraphy also differs from iconography, as it is confines itself to meaningful symbols containing messages.
La epigrafía (del idioma griego επιγραφή: escrito sobre) es una ciencia autónoma y a la vez auxiliar de la Historia, cuyo objetivo es el estudio completo de inscripciones, tanto en su estructura, soporte, materia, como su forma como en su contenido escrito, pero también la función que desempeña tal evidencia. La finalidad de la Epigrafía abarca no sólo el desciframiento, lectura e interpretación de las inscripciones, con el fin de obtener la mayor cantidad posible de información de las mismas, sino también el estudio de los materiales y soportes (piedra, metal, madera, hueso, cerámica, entre otros) sobre los que se ha escrito, y cómo se ha escrito, así como la finalidad, la función para la cual se concibió y se destinó tal elemento. Según las convenciones internacionales (especialmente para la Unesco), la existencia de epigrafía propia es el marcador que indica el paso de una cultura de prehistórica a histórica, especialmente cuando entre sus inscripciones cuenta con anales y crónicas. La Epigrafía se relaciona de forma directa con ciencias como la Historia Antigua, la Arqueología, la Filología y la Paleografía y, complementariamente, con otras como la Numismática, la Historia de las Religiones o el Derecho Romano. Aunque también estudia las leyendas presentes en las monedas, el estudio especializado de las inscripciones que aparecen sobre estas es propio de la numismática.
