Fluctuat nec mergitur (it floats but does not sink) has been
the motto of the City of
Paris since at least the fourteenth century, though it was confirmed officially in the nineteenth. The
image refers to the ship of the Parisii — the ancient tribe who gave Paris its name — which appears on the city's coat of arms. Students should note that the phrase achieved particular emotional resonance after the terrorist attacks of November 2015, when it became a rallying cry across the world, appearing on public buildings, in social media posts, and in improvised
memorial verse. This contemporary reinvigoration of a medieval motto illustrates how Latin phrases can remain genuinely alive — able to generate new meaning in new historical contexts. Related terms include the ship of state (a classical metaphor
going back to Alcaeus and
Horace), nauta (sailor), and the broader maritime metaphor in political and elegiac poetry.
