As we tend to reduce everything to its formal overall qualities, visuality is usually associated with a "visual turn” or we also cast visuality in various kinds of expressive contexts—in a disciplinary context, as some visual expression without taking into account either their “visual environments" or original contexts.This way, the Western world's self-reflections often do not reflect the genetic traces of visual thinking and its corresponding constructions and technologies because we still write under the auspices of scientific rule systems in which visual paradigms are implanted in a hidden or transfigured manner.The genealogy of Western visuality's deep structures is a historically cultivated multisensory complexity based on a combined body position-vision-understanding concept, which will determine the visualities' polysensoriality allowing both Gratias tibi, domine, pro omnibus quae videmus! and Esse est percipi. In pre-semiotic theorisations, in which the perception of signs (semas) is related to reading visible images from the surface, it was realised in visual cultural constructions - theoria practices which at first were more related to the preparation of visions, while later the Romans associated them with the perception of what appears. In all cases, the images were verbalised, with the result that the later etymologies of the termini technici for all practices associated with theoria and later derived from it are related to vision.The paper is devoted to tracing the origins of complex theoria practices and the creation of visual dominance across sign systems.
