This colourful picture has holes where it eyes should be. We've been told that it used to have glowing red eyes. This look was achieved with red plastic and a light bulb. You can clearly see this painting in the photo below which shows an old Museum display.
We are told that this cross formed part of an old Museum display on Ritual Magic as did the paintings below.
Maybe someday we'll have a temporary exhibition on Ritual Magic which would get these items on display and give us a chance to consider the subject in greater detail.
