Sophisticated geometry – the branch of mathematics that deals with shapes – was being used at least 1,400 years earlier than previously thought, a study suggests.
Research shows that the Ancient Babylonians were using geometrical calculations to track Jupiter across the night sky.
It had been thought that complex geometry was first used by scholars in Oxford and Paris in medieval times.
They used curves to trace the position and velocity of moving objects.
But now scientists believe the Babylonians developed this technique around 350 BC.
