Polish Alphabet - prior to the arival of Christianity

Does anyone have any information regarding the Polish alphabet prior to Christianity?
I have heard that the church decided it was pagan/bad and destroyed all records of the old alphabet.

Are you referring to "Runes?"

are you sure you can talk about anyhing Polish before Christianity? you know Poland was established somewhere around the year 999/1000, so you've got ten centuries or so difference. perhaps you're referring to some slavic tribal writings then?

There wasn't Poland before Christianity.
And I doubt that these people had any alphabet.

Prior to the latin influence it was an unwritten language, a lot of languages were back then.
