What the author says is correct however i will like to add a little more to that, the correct saying is « après moi le déluge » is/was in the (Eighteenth century) The expression « after us, the flood »(in English) is attributed to Madame de Pompadour at the address of her lover Louis XV during the defeat, 5 November , 1757 in Rossbach, Franco-Austrian troops against the Prussian army of King Frederick II. I recommend reading this it’s really interesting 😊 https://www.forgottenbooks.com/en/download/The_Eighteenth_Century_1000691529.pdf (I hope this explanation is understandable because I did my best to translate it, English is not my native language)
