Head of the Virgin (Pittoni)
It is possible that Pittoni looks for further mystical strength in it, exasperating the interpretation of the critic Alexander Nagel on Leonardo da Vinci's "Head of a Woman" in which "the eyes do not focus on any outward object, and they give the impression that they will remain where they are: they see through the filter of an inner state, rather than receive immediate impressions from  the outside world. It is the attitude of being suspended in a state of mind beyond specific thoughtunaware, even, of its own body...here an inner life is suggested by a new order of pictorial effects, without recourse to action or narrative."
