choreographie

Via Public Domain Review:

Collection of Dances in Choreography Notation (1700)
Images extracted from the latter half of Choregraphie, a book first published in 1700 which details a dance notation system invented by Raoul-Auger Feuillet which revolutionised the dance world. The system indicates the placement of the feet and six basic leg movements: plié, releveé, sauté, cabriole, tombé, and glissé. Changes of body direction and numerous ornamentations of the legs and arms are also part of the system which is based on tract drawings that trace the pattern of the dance. Additionally, bar lines in the dance score correspond to bar lines in the music score. Signs written on the right or left hand side of the tract indicate the steps. Voltaire ranked the invention as one of the “achievements of his day” and Denis Diderot devoted ten pages to the subject in his Encylopdédie.

The diagrams really get my imagination going.

mechanised birdsong

A mechanical singing bird mechanism. Made around 120 years ago in Paris, probably by Bontems. In the film I hope you can identify all the major parts and see them working together to make the sound. The mechanism was in a rusted and seized state and has been restored. Surpisingly the bellows are in good original condition. See our channel for more, much more.

If this is for real, it’s very impressive! Actually if it were not real it would be impressive too. See more at the house of automata. (via sciencedump)
