A circular filter of a water jug is perforated with cube-shaped designs and a man raising his right hand over his head; the other hand is directed to the right.
The hair is not clearly detailed, and the eyes consist of two holes; the fingers are clearly delineated. His body is surrounded by a frame that is raised above the rest of the design.
This filter is similar to the arabesque windows, which aim to allow a view of the exterior, while protecting the privacy of the interior. It also gives a wonderful muted light when the sun shines through it.
