Ornamento e scrittura

Ornament presents organized information that is entirely distinct from text as encoded in letters and signs. Ornament does not communicate a message in written language, but instead in a subconscious language. I will use the example of typography to discuss this difference. When early typeface fonts for printing were cut by hand, they were created with the aim of having maximal legibility, guided by aesthetic considerations. They were serif fonts (in which open lines end with a dot or T-stroke), like present-day Times and Garamond.
The introduction of radically new typefaces at the beginning of the twentieth century confirms that removing the ornamental serifs also removes a level of meaning. Sans-serif fonts such as Helvetica were popularized along with the modernist Bauhaus design style. They were promoted for their mathematical simplicity. It has been experimentally established that sans-serif fonts degrade legibility. People's reaction to these stripped-down typefaces was strongly negative; so much so that the ancestral sans-serif font was called "grotesque" by the Berthold foundry, which introduced it commercially (the sans-serif typeface Berthold Akzidenz-Grotesk eventually gave rise to Helvetica).

The transition from sans-serif to serif fonts shows clearly how ornament works to make form clearer, sharper, hence more distinguishable. Classic serif fonts go much further in establishing a positive emotional connection with the reader. In (Salingaros, 2000) I argue for the necessity of detail from hierarchical arguments. It is not just any added detail that improves the legibility of the font, however. Adding dots or small cross-strokes anywhere other than at the terminals of open lines (and even there, at some arbitrary angle) would degrade the font.

Ornament organizes detail in a very precise and sophisticated fashion in order to make a larger form more comprehensible. Adjustments are necessary for a better comprehension of letters. The most effective serif fonts are vastly more complex mathematically than a similar sans-serif font. They show substructure on a hierarchy of decreasing scales. A serif typeface doesn't simply add end-strokes; the entire font is adjusted so that new, more detailed elements cooperate to define a coherent whole. Correcting an old misunderstanding, ornamentation does not superimpose unrelated structure; rather it is an operation that generates highly-organized internal complexity. It therefore has to be extremely precise in order to be effective.
