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.
