Lettero&#8217;s radical essentiality makes it capable of expressing the most abstract logical functions. Like the mathematical signs, +,-, \/, %, Lettero is a potentially universal sign, free from connection to different languages, but its representational possibilities are much greater because of the intuitive significance that the logical connection takes on once drawn in the figure. Research on Lettero was published in 1986 in Chip, an Italian computer science journal, in an innovative article that proposed an iconic translation of the Basic programming language.   <\/p>\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"235\" height=\"312\" src=\"https:\/\/homo-extensus.ai-book.it\/wp-content\/uploads\/2025\/06\/letterographia2.jpg\" alt=\"\" class=\"wp-image-909\" srcset=\"https:\/\/homo-extensus.ai-book.it\/wp-content\/uploads\/2025\/06\/letterographia2.jpg 235w, https:\/\/homo-extensus.ai-book.it\/wp-content\/uploads\/2025\/06\/letterographia2-226x300.jpg 226w\" sizes=\"auto, (max-width: 235px) 100vw, 235px\" \/><\/figure>\n\n<p>Lettero Basic (1986).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&#8220;Letterographia&#8221; research develops syntactic and logical ideograms using a sign traceable to a minimal human figure.
