FATHOM

Depth is not extension.
It is binding system.

Material and space are not separated.
They collapse into each other.

Layering does not produce illusion.
It produces density.

FATHOM does not describe depth.
FATHOM maintains depth as access condition.

Transparency does not open.
It shifts boundary.

Bildkörper is not in space.
It organises space.

Light is not visible.
It binds.

No final viewpoint.
Only degrees of approach.
