Photo is Stela D from the Copan ruins in Honduras. One of my favorites. Link to original photo, satellite data and other neat stuff by Stephanie Parker.
The overly-long art school title to this linocut is “Mechanical Man Contemplates His Existence In Space and Time”. Seriously! The imagery is a combination of two fascinating historical objects. The background is one of the faces of the Orloj in Prague, the oldest functioning astronomical clock in the world. The figure is one of the first known examples of a completely self-contained biological automaton. Built in 1650, it has been attributed to Juanelo Turriano, a brilliant Renaissance engineer who was known to have crafted mechanical wonders for Emperor Charles V. After Charles passed away, however, Turriano drew accusations of witchcraft and he narrowly escaped torture at the hands of the Inquisition.
