This paper discusses an example of Scottish-Polish cooperation on research, undertaken at the turn of the twentieth century, into the dialogues and philosophy of Plato. Two scholars were involved in this research: the Scottish classical scholar and historian of ancient philosophy, Lewis Campbell, and the Polish Plato scholar and philosopher, Wincenty Lutosławski. Their research on the chronology of Plato's dialogues is analysed and the reception of their works discussed. The paper is enriched with some excerpts from their correspondence.
