The story behind the word. Ancient Greeks visualized the sky as a hollow sphere turning on a central pivot called the 'polos'. Medieval Latin cartographers used 'polaris' to refer to the celestial poles and the stars resting near them. Eventually, the term grounded itself on Earth to mark the freezing geographic ends of our planet's rotational axis.
