This is in a mode called “columns” which, as it was described to me on a panel in SFContario, is written so that the left and right columns make sense alone, and the poem read as a whole (left to right) makes a different kind of sense. The lines in the middle go in both separate columns. It wasn’t hard to write, but it was hard to format — thanks to Mack Muldofsky for special help with that! The first column is the ancient world, the second column is the Renaissance rediscovery of it. Read down each side, and then across.
