I'm not sure this belong to literature but i give it a try.
A great French writer to many of my countrymen is Frederic Dard
Frédéric Dard - Wikipedia, the free encyclopedia
the unforgettable creator of San Antonio,and i found that a few of his novels have been(to my amazement)translated into English.A question came ot me about the difficulty of such a achivement,the same that some of you raised about poetry.Can slang ,with all it words creation and pull by the hair metaphores,be properly render into another language without it loosing nearly all it's potenty.For slang and gutter language take it's force from deep within the spirit of a country.
The few titles on wiki already show's that the beauty and meaning is lost when past into English.
