A motto of Paris, France, which has a ship as its emblem. This motto is also translated as, "Unsinkable". Like other cities that have existed for a long time, Paris has had its bad times and its good times.

In ancient times, Paris was called Lutetia Parisiorum, from a Gaulish-Latin word Lutetia [lutum is a Latin word meaning "mud"], a fortified town of the Gaulish tribe of the Parissi). The name Lutetia literally means "swamps" with its muddy and slimy characteristics.
