X1 City Ring

In 1637, René Descartes lay watching a fly move across his ceiling and asked a question nobody had thought to ask — how do you describe exactly where something is? The answer became the coordinate system. The X axis. The line of origin from which every other point in space is measured. Every map ever drawn. Every city ever built. Every distance ever calculated. All of it begins at X₁. The amethyst in this piece sits at that point. Not decoration. Not accent. The axis. The fixed point. The place everything else is measured from. She is not on the map. She is where the map begins.
