Lipgart, Ernst Karlovich – Portrait of Grand Duke Mikhail Nikolayevich Hermitage ~ part 07

The picture has something of this: people, man, wear, facial hair, veil, royalty, mustache, god, lid, portrait, sword, saint, leader, elderly.
Perhaps it’s a painting of a man with a long beard wearing a blue uniform and holding a sword in one hand and a white beard in the other hand.
