Don Diego del Corral y Arellano. Diego Rodriguez De Silva y Velazquez (1599-1660)

The picture has something of this: people, wear, portrait, man, priest, administration, facial expression, outfit, leader, lid, indoors, veil, furniture, royalty.
Perhaps it’s a painting of a man standing in front of a table with a piece of paper in his hand and a red table cloth on the other side of the table.
