HELP! trying to remember the name of this famous painting!!? - large oval mirror

which is European, I think, since 1600, a married couple, I think the man is so powerful? You do not see the painter, who paints, but is a mirror image of him in an oval wall mirror, the rear part of the room is. next to the mirror is a chain of beads. I think it's a dog's loyalty?

Man is very pale, with a pointed chin. wearing a hat.
the woman is young, her hand on her stomach? She wears a red dress, you may be pregnant or a dress is great.
