The conceptualization of long periods and how they fit into our lives which was originated from studying geological strata.
Realizing that time is longer than we think was problematic in the 18th-19th century–the earth is not ~6,000 years old, there are no artifacts of humans in geological strata that were uncovered during the industrial revolution, even the dinosaurs had to be conceived of.
Darwin once said time is inconceivable, yet articulated evolution as the product of small changes over long stretches. It can be powerful to grasp inconceivable lengths of time.
