If anyone is wondering, it's Jael or Yael, and Sisera. He was a defeated Canaanite general who fled to what he thought was a friendly village, but Jael had Israelite sympathies so she hammered a tent spike through his head while he slept. The image is from an illuminated 14th century manuscript from Germany.
And for anyone else wondering, im pretty sure this meme is from womens subs because they get told things like "youd be prettier if you smiled" or other cunty shite like that
That was not usually part of the medieval illuminator’s mindset, I’m afraid. Communicating the social status and role of the two Biblical characters in a familiar context for the reader would typically have been more important to them.
