It could be that in the picture there is not two people but one, the older (Dee) rejuvenates himself into the younger (Bacon). The transformation is in one sense from physically aged (base metal ?) into youth and vigor (gold?) but carrying ones knowledge and experience (the wine) into the new container. That brings to mind the biblical expression of putting wine into new or old bottles. The young man on the left holds a ball or something in his right hand. Just a thought.
