"Boussole" is a French word that translates to "compass" in English. It refers to a navigational instrument used to determine direction relative to the Earth's magnetic poles. A compass typically consists of a magnetized needle that aligns itself with the Earth's magnetic field, allowing users to find their way in unfamiliar terrain. In literature, "Boussole" is also the title of a novel by Mathias Énard, published in 2015. The book explores themes of travel, culture, and the interconnectedness of different civilizations through the journey of its protagonist, who reflects on his experiences in the Middle East and Europe.
