We can pretend that JMW Turner visited Greece. His watercolors of the Acropolis and the Gate the Theseus tell us of his sympathies for Athens. To make those, he studied drawings by artists who had been there. If we want, we can imagine that he visited Marathon. With his back to the bay, he walked toward the plain where the sunset was trumpeting the old battle, Golden grass shone on the Tomb of the Athenians. He could make a watercolor right there.
Or we might ask what he would think if his spirit strayed to Marathon, Texas. It can look just like this.
