When volcanoes erupted, civilizations like the Aztecs, Hawaiians, and early Greeks offered treasure or human lives to calm fiery gods.

More than poetic language, lunacy has roots in ancient beliefs. Thinkers like Pliny the Elder claimed the full moon triggered madness and strange behavior. Moreover, Moon gods such as Selene and Thoth were said to influence dreams and time, which shaped both fear and ritual.

In many ancient cultures, the left hand stood for chaos, inspiring the Latin word “sinister.” Yet, in Zulu and Incan traditions, left-handed people were thought to hold special prophetic powers. Because lefties were rare, they were both feared and revered. Your dominant hand might have meant the difference between being blessed or cursed.

The Mesopotamians imagined the Earth as resting on Apsu, the watery abyss, and explained earthquakes as caused by sea beasts moving beneath. Similarly, Norse myths spoke of Jormungandr, the world serpent coiled under the seas. Back then, science hadn’t yet explained these mysteries.

Before science explained sound waves, many ancient cultures believed echoes were more than just sound bouncing back. Instead, they saw them as spirits answering the living. Over time, these mysterious repetitions became part of folklore, reinforcing the idea that unseen forces were always listening—and sometimes even whispering back.

Bones weren’t seen as useless because they held meaning and power. The ancient Celts, for example, kept enemy skulls for protection. In many cultures, hair, teeth, or even mummies were believed to carry energy or wisdom. Later, churches kept saints’ remains as relics, showing that power could live on after death.
