Art_4 : the wise aristocrat #90

This painting is from 1694, one century younger than the portrait depicted in Art_1. I found it in an Antique fair and was immediately stuck by the blue eyes of the character. He must be a noble man as his coat of arms is painted in the upper left corner of the painting. I have tried to identify the family which owned that coat of arms, without success for the moment, the French armorial is so huge that only luck would lead me to the right name. The man seems wise, looks calm and thinking. But his eyes are bright and look around for ever...
