After writing about Charles J Strong’s Book of Designs a couple of days ago, it seems pertinent to point the way to a far more essential Art Nouveau design book which can also be found at the Internet Archive. Combinaisons Ornementales was a collaboration between Maurice Verneuil, George Auriol and Alphonse Mucha published in 1901, and comprises 60 plates of beautifully elegant designs (“multipliable to infinity with the aid of a mirror”) which range from Mucha’s abstractions to Verneuil’s flower motifs. The examples shown here are all by Mucha; I borrowed one of the flourishes and the peacock feather for the Dodgem Logic cover design earlier this year.
For a quick look at all the plates, the NYPL Digital Gallery has scans. Mucha produced another design book the following year, Documents Decoratifs, although I’ve yet to see an edition of that online.
