Zeno of Amsterdam did not give this Monad a special name.

The disc shows how the stone is "moved away" by the artist in a sideways direction from a single point towards the edges, leaving folds on both sides.
The material of the liberated segment is extremely thin and therefore, light shines through it.

It seems that the artist – by using a fan shape - also wants to point out to us, via the removal of the stone material, that our current field of vision can be further broadened on the journey.

If we take this Monad as referring to our inner eye, it is significant that the field of vision in the picture is directed to the left, whereby on the identical rear side the opposite is true: when the Monad is turned around, the field of vision is directed to the right.

In the Pilgrim (The Labyrinth), Comenius describes the arduous story of psychological cleansing. The outcome is the same: liberation comes by providing the inner light with the opportunity to break through.

Zeno of Amsterdam was a keen reader. It is possible that he read about Comenius. It seems the motive for this Monad may have stemmed directly from Comenius though in our opinion, this may not be the case. It is more likely that Comenius and Zeno of Amsterdam drew inspiration from a similar inner reality experience.
