I learned a lot on my tour of the Colosseum, Palatine Hill, and the Roman Forum. However, the thing that resonates the most with me is that the Romans were so advanced. The floor of the Colosseum was wooden, covered in Egyptian white sand and hid an elaborate underground system for the storing of animals which would pop up through trap doors.
I closed my eyes and I could hear the roaring of the crowd, urging warriors to battle on. I opened them to see the worn marble where wealthy men and senators would sit. I walked the many steep, angled steps where people were placed based on their status and looked down upon what was once the greatest spectacle the world has ever known.
