A European language unknown to Europe

Enzo Rivellini, an Italian minister of the European parliament, rose to address the assembly first in Italian, then in Neapolitian, the language of the Kingdom of Naples that, as he asserted, is not merely a dialect, but a language with its own vocabulary, and its own literature. The language, he sought to remind them, was spoken in European courts not so long ago.^*

According to Corriere della Sera, his discourse in Neapolitan left the translators puzzled. How to translate 'o pata pata 'e l'acqua?

I wonder if the Basques address the European Parliament in their language.
