This is a picture of an old model of the universe, made by the blacksmith A. Andér, based upon the description given in Toward the light. It was discovered to be a misunderstood model as the action path of the four mother stars stays on the same plane as the orbit path. The mother starts actually spiral forward around the orbit path. Here's a couple of links with an accurate animation of the mother stars. http://www.vandrermotlyset.net/planeter/index.html
