The dust; the dust and the heat; the dust and the heat and the blaring sun. Even now, the conditions are nearly suffocating, when they were matched by the smell of blood, the shrieks of pain and roars from the crowd, it must have been overwhelming. With the stage at ground level and rows of seats rising upwards, you can almost see the ghosts of gladiators, dressed in bronze armor, stepping out into the cauldron, god-like with life and death in their hands. At night, the ghosts seem to come to life. The lights show the amphitheater is still imposing two millennia later, but they also cast shadows that shift and move, remembering all those who met their bloody end there. The Colosseum, almost a ruin, still very much alive.
