Tuwim proved Polish and French may sound the same and some claim French is the most beautiful language.
Yes, melodically, Polish and French are close. It is so because back in past Slavic (ie Sarmatian, ie Galic, ie Celtic) population of Galia spoke language closest to the language of Slavs (ie Sarmatian, ie Galic, ie Celtic) that would later encompass Poland`s population.
Caesar`s hike (from 58 to 50 bc) and enormous Roman genocide in Gaul, changed the situation, when in single military operation out to 3 million of Slavs (ie Gauls, ie Celts, ie Sarmatians) was massacred and killed. There are records of more then 300 exterminated clans, entire tribes extinct. Plus, great magnitude of people was sent to slavery back to Rome and allover the Roman empire, sent to slave markets allover the known world. Then, on such a weakened remaining Slavic element in Gaul, Romans introduced their administration and new settlers from already Latinized Roman speaking areas. Population mixed in every sense, in new environment and modern day French nation and language were formed. So, only in melody of language, Slavic element prevailed.
I mention this in deep honor and mourn for the fallen ancients and their lives taken in act of utter violence and injustice. I pray to God, for the right on truth, for them, for us who still live in that continuity, for our entire civilization.
