![Cogwheel in sculpture by Antoni Clave, Parc de la Ciutadella, Barcelona, Spain [enlarge]](http://farm3.static.flickr.com/2558/4209103990_091f7010de_o.jpg)
Cogwheels that evoke the times of industrial revolution in Europe, times of textile factories in Catalonia, of heavy machinery, of steam and rising unions, of a powerful bourgeoisie interested in new technologies, in productivity, in capitalism and also in the latest artistic trends, as a way to rebel against the heavy yoke of aristocracy and monarchy.
This cogwheel is part of a bigger sculpture placed in Parc de la Ciutadella in 1998 to celebrate the centennial year of the Universal Exhibition in the city. It is a modern sculptoric work by Spanish painter, sculptor, stage and costume designer Antoni Clavé (1913 –2005).
