Ortensia Mancini by Jacob Ferdinand Voet, 1670s
Very similar to the Conti Sessi portrait, it reinforces the style of beauty that was fashionable for the time and that the well to do women aspired to. Another very dark and poorly lit portrait. There are many famous old paintings that are in desperate need of cleaning, and many are poorly lit intentionally to stop their colours fading, yet maybe leaving all the soot and dirt on preserves the colours better for whenever they do get cleaned eventually.
