“Rest on one's laurels”in other languages

Same idea, different pictures

English, French and Italian rest on the laurel wreath that crowned winners in ancient Greece and Rome: se reposer sur ses lauriers, adagiarsi sugli allori.

French also has les délices de Capoue, the delights of Capua. After his great victory at Cannae in 216 BC, Hannibal wintered his army in the comfortable city of Capua, and Roman historians blamed its luxuries for softening his troops.
