I reckon, it's a woman looking out of the window about three metres behind him.
@mina Oh, yes, you're right. Another woman in the background... 😓
Can you blame her? She got tired and is quietly sharpening her dagger.
Just in case.
@mina Very interesting hypothesis... I was wondering why so many women in the background and a proud man in the foreground, as if he were giving them part of his ancient wisdom. Even there's a black woman portrayed in a very different way to the other white women. Everything's quite odd.
