A picture of Jesus making out with Judas from a 14th century illuminated manuscript

So the best part of this isn't the completely wrong take on a cultural act. Instead it's the accidental highlight to something not even in the picture. For a very long time religious books were hand written (no duh). What most don't realize is that many were written in monasteries because monks made good scribes, what with them being generally literate and with more time on their hands. Now, just because a bunch of guys swore off the sex didn't mean it wasn't always on their minds. Many manuscripts, have interesting pictures drawn in them that are of the hiding in plain sight variety.
