Here's sort of an engraved invitation to tomorrow's dragonfly talk, by way of the Vitruvian Darner:
This dragonfly (the Happy-face Dragonfly) shows the nice proportions of da Vinci's Vitruvian Man.
I was curious how these proportions would compare with other dragonflies, so I tried a Vitruvian Glider, based on a Wandering Glider:
Not surprisingly, the broad, wide wings of the glider give it distinctly different proportions.
Both of these sketches were taken from photographs, so the proportions are true to life.
Off to Prescott tomorrow.
