Portrait of Fyodor Ivanovich Chaliapin as Boris Godunov in Mussorgsky’s opera of the same name Alexander Golovin (1863-1930)

The picture has something of this: wear, traditional, culture, decoration, design, ancient, style, symbol, gold, antique, temple, church, spirituality, god.
Perhaps it’s a painting of a man with a beard wearing a green coat and holding a cane in his right hand and a red curtain behind him.
