The Greek historian Thucydides was the first to relate tsunamis to submarine quakes.
The first is the Greek historian Plutarch who first invented it. Repeated by many Greeks, it told the story of a king known as Egyptos who offered his daughter as a sacrifice to the Nile to avoid the gods’ wrath.
After he did that he committed suicide by throwing himself in after her. Since then, Plutarch said, the Egyptians began to sacrifice a virgin every year.
If you seek a more extreme measure, in the famous panic of 33AD, Tiberius banned all interest payments for three years among other measures.
