“The Vertical & the Horizontal” Legend has it that Emperor Constantine saw a cross shape in the sky and that’s how we arrive at the use of it as a symbol. But that we have a legend at all is part of the story itself, as well. We tell stories because we like them. We repeat them to others because they resonate with the human experience in some way. So why did we spread the legend of the Crux Immissa version instead of the others, when there’s plenty of evidence it could have in reality been another shape entirely?
