The first painting is an illustration to the following poem from the 1200s by a woman from Antwerp.

Knowing love in herself.

I do not complain of suffering for Love,

It is right that I always obey her,

For I can know her only as she is in herself,

Whether she commands in storm or in stillness.

This is a marvel beyond my understanding,

Which fills my whole heart

And makes me stray wild in a desert.

 

The other sketch is about control, and the last two are about people coming together to talk about exciting new ideas.
