Rocco Mangieri2026-03-222026-03-222008https://andeanlibrary.org/handle/123456789/78685Many neoplatonic Italian paintings of the XV century are elaborated and based on hermetics codes.The hypothesis of this work is the use of a no-western graph-visual sign (the graphic sign of the sound ohm) like a hidden hieroglyphic in the painting.If this is certain or true it is added or annexes a new sense in the reading of the image.A visual and graphic sign recomposes all the meaning of the painting.esArtHumanitiesarticle
