Quote by Anaximander: “The earth is a short cylinder floating free, unsupported by anything.”

Anaximander proposed a revolutionary model of the Earth as a celestial body freely suspended in space, rather than resting on something. This demonstrates an early attempt to understand the universe through rational observation and deductive reasoning, moving beyond mythological explanations of supports like pillars or turtles.

This audacious hypothesis challenged common beliefs of the time that the Earth rested on something. Anaximander's model was a significant leap in early cosmology, seeking a natural and symmetrical explanation for the Earth's position in the cosmos.

Greek philosopher from Miletus who lived approximately 610–546 BCE, a student of Thales. He is known for developing the concept of the apeiron — an indefinite, boundless source of all things — and for producing one of the earliest known maps of the world. Only a single fragment of his writing survives, quoted by later philosophers.
