- [Gonzalez] Grammar of trees.   
< Grammaire des arts du dessin . 1863 [Blanc]. This books is an attempt to present all the arts (but mainly architecture) as ruled by a grammar (for instance the three classical orders: Doric, Ionian, Corinthian). Since then, this approach has inspired a lot of architects, as shows at length [Picon], and perhaps even the Cubists through Cézanne?

- [Stiny] George Stiny and James Gips propose a grammar of forms, inspired by the generative grammars of Chomsky. This approach is never quoted in image processing or algorist literature. But she was never forlorn, as shows a review presented in 1999 by Gips during a MIT symposium. Computer implementations of shape grammars, by Gips in MIT symposium. Available Online (PDF). It contains a list of 26 forms grammars, several of which are available as softwaretools.
