Digesting Duck


The Canard Digérateur, or Digesting Duck, was an automaton in the form of a duck, created by Jacques de Vaucanson in 1739. The mechanical duck appeared to have the ability to eat kernels of grain, and to metabolize and defecate them. While the duck did not actually have the ability to do this—the food was collected in one inner container, and the pre-stored feces was "produced" from a second, so that no actual digestion took place—Vaucanson hoped that a truly digesting automaton could one day be designed.

Voltaire wrote in 1741 that "sans la voix de la le Maure, & le canard de Vaucanson vous n'auriez rien qui fit ressouvenir de la gloire de la France." ("Without the voice of le Maure and Vaucanson's duck, you would have nothing to remind you of the glory of France.")

The Duck is thought to have been destroyed in a fire at a museum in 1879.[1][2]

Operation

An American artist's (mistaken) drawing of how the Digesting Duck may have worked

The Duck was the size of a living duck, and was cased in gold-plated copper. As well as quacking and muddling water with its bill, it appeared capable of drinking water, and of taking food from its operator's hand, swallowing it with a gulping action and excreting what appeared to be a digested version of it.[2]

Vaucanson described the Duck's interior as containing a small "chemical laboratory" capable of breaking down the grain.[2] When the stage magician and automaton builder Jean-Eugène Robert-Houdin examined the Duck in 1844, he found that Vaucanson had faked the mechanism, and the Duck's excreta consisted of pre-prepared breadcrumb pellets, dyed green. Robert-Houdin described this as "a piece of artifice I would happily have incorporated in a conjuring trick".[2]

Modern influence

A replica of Vaucanson's mechanical duck, created by Ian Huynh, was part of the collection of the (now defunct) Grenoble Automata Museum. Another replica was commissioned privately from David Secrett, an automaton maker known for his archer figure.

The duck is mentioned by the hero of Nathaniel Hawthorne's short story "The Artist of the Beautiful", and is referenced and discussed in John Twelve Hawks' novel "Spark". A fictitious enhancement of Vaucanson's original duck, the mythical counterpart to the one seen in the image above, figures prominently in Thomas Pynchon's historical novel Mason & Dixon. The duck is referred to in Peter Carey's novel, The Chemistry of Tears.[3] Vaucanson and his duck are referred to in Lawrence Norfolk's 1991 novel Lempriere's Dictionary. The Duck is featured in Lavie Tidhar's The Bookman, in the Egyptian Hall, alongside the Turk.

In 2006, Belgian conceptual artist Wim Delvoye introduced the world to his "Cloaca Machine", a mechanical art work that actually digests food and turns it into excrement, finally fulfilling Vaucanson's wish for a working digestive automation. Many iterations of the Cloaca Machine have since been produced; the current iteration sits vertically, mimicking the human digestive system. The excrement produced by the machine is vacuum-sealed in Cloaca-branded bags and sold to art collectors and dealers; every series of excrements produced has sold out.

The duck is used as the symbol for the software company Automatic Duck, Inc.
