Etymology
The term 'longitude' comes from the Latin word 'longitudo', which means 'length'. The concept of longitude has been known since ancient times, but it was the invention of the marine chronometer in the 18th century that allowed sailors to calculate their longitude accurately at sea. Before this development, mariners struggled with determining their position longitudinally while navigating. The prime meridian was established at the Royal Observatory in Greenwich in 1884, where zero degrees longitude runs, demarcating the Eastern and Western Hemispheres. This has since become a fundamental part of world geography and navigation.
