We know that many scholars and philosophers of antiquity were convinced that the Earth is round. How could they have been so sure without access to all the technology we have today? Through deductive reasoning based on their observations.
Delve into the heart of antiquity and discover how scholars proved that the Earth is spherical.
Conceived by the Space Department of the Time-Space Laboratory at the Paris Observatory – PSL and produced by Orbital Views, this immersive experience puts you in the shoes of the thinkers of the time and invites you to experiment for yourself.
Explore three interactive workshops
Meet, in your mind’s eye, great minds such as Eratosthenes, Aristotle and Pliny the Elder. Grasp their insights, retrace their steps, and experience the power of simple observations that changed our view of the world.
Through experimentation, rediscover how observation and reasoning enabled scientists to understand the world, long before the advent of modern technology.
