Art Word of the Day: Atectonic
Atectonic is a term mostly used in sculpture and architecture
that refers to any shape or form that protrudes into open space, or contains within it a sense of "open form".
Coined by Heinrich Wölfflin in 1915,
atectonic is paired opposingly with tectonic. Wölfflin also used the terms free/strict, irregular/regular but settled on "open / closed" as this offers a more general and ambiguous meaning, which is more suitable for this style.
17th century paintings were typically atectonic
whereby the style "everywhere points out beyond itself and purposely looks limitless", in contrast to the self-contained entity of a closed form, in which everything is "pointing everywhere back to itself" ~ Wölfflin 1950
Closed/Tectonic style by Raphael
With the advent of film, moving pitcures were seen as essentially open in form whereas the individual stills were considered closed in form.
More closed/tectonic style by Rahael
Also see boss, projection, and rugosity.

Every day I make an attempt to add a little bit more art knowledge to the Internet, one word at a time. Realizing there aren’t many comprehensive and complete online art dictionaries, I set out on a mission to compile my own.
