ABN's caption entry:
"We Are One: History is Destined to Repeats Itself"
Justification:
As each culture seems to race away from each other, attempting to learn from others "mistakes," attempting to not go in the same direction. The similarities are always there, just redefined for each time period, hence the subtle similarities. We, as a species and creation are all one, so in a sense, there is not much of an escape and we are bound just as the image is above. We are bound to repeat history as it continues to do. The same looming cloud(s) encompasses each time period and watches as it attempts to escape but is unable to.
