Max Slevogt (1868-1932) – The Singer Francisco d’Andrade as Don Giovanni in Mozart’s Opera (The Red d’Andrade) Alte und Neue Nationalgalerie (Berlin)

The picture has something of this: people, man, saint, costume, woman, cross, wear, veil, god, blood, dress, Renaissance, book, cape.
Perhaps it’s a painting of a man in a red and white outfit holding a sword and standing next to another.
