It occurs to me that I've neglected to fully explain where this design came from other than to mention that I 'noodled with it', that the subject wasn't really Venetian and that someone named Moroni painted it. If you're familiar with the painting, feel free to skip this post. If not, well, the noodling was all me, but the painting itself was executed by the mannerist painter Giovanni Batista Moroni around 1560. Allegedly the subject is the Duke of Albuqurque (as I said, not a Venetian) but Moroni, was Venetian.
I've always liked this painting, if for no other reason than the man looks so earnest and postively normal rather than like some religious icon in a dogma where nobility is worshipped as was so often the case in renaissane portraiture. If you click on the duke's name, it will take you to the "Art Unframed" site, where you can view hundreds of famous historical paintings and even have a copy made of the one that you fancy. I've never used their services beyond browsing, but the idea intrigues me as I've never developed the brushwork discipline necessary to paint in the mannerist style in order to copy the painting myself.
