This is a detail from a Madonna by Bernardino Luini, a painter in the circle of Leonardo da Vinci.
The painting has sustained a bit of damage over the centuries, so I did a digital restoration and added some sublime-looking clouds. The original is in the collection of the National Gallery in London. Not sure if it is being restored. I almost wonder if some goddess incarnated in High Renaissance Italy, whose face became a model for Leonardo and Luini.
