Szukana fraza: [Abstract = "He copied and incorporated some lines from Jan Kochanowski`s \"Szachy\". Paszkowski gave an account of the war straight from the Zbigniewski`s work as well. He presented polish propositions for a peace treaty as a final agreement between two enemy sides. Finally, what the deeper comparison shows, he may have also used a third source in his poem to plagiaries from. In that case \(what requires a deeper insight\) the whole content of \"Chorągiew sauromatcka\" would turned out to be a mixture from several other works."]
