Header Art

I've been asked about the art piece

 used in my header

and although it is displayed in the sidebar 

it doesn't seem to enlarge enough to be easily read....

so here's a repost!

 The mysteries of flight may be symbolized by the story of Icarus 

whose wings of wax and feathers 

melted as he flew too close to the sun 

sending him crashing into the sea. 

But the secrets of flight were hidden 

not up in the air 

but under the ground as fossil evidence.

The concepts of balance and symmetry

 have long fascinated artists. 

The dinosaur archaeopteryx

possessed asymmetrical feathers, 

the leading edge being narrower 

and more streamlined.

This enabled the wings 

to slice through the air permitting 

at least rudimentary flight.
