Bruno and Caravaggio – the heretic philosopher and the heretic artist in the works of Gustaw Herling-Grudziński The present text follows the extraordinary “double portrait” of Bruno and Caravaggio – rebels in science and art, who are being „painted” by the Polish emmigrant writer in his works. They live together in his thoughts for many years. Herling writes series of texts about them, in which the position of the main character changes, but the remaining one is always inseparably present. The texts analyzed are his essay “Caravaggio” (1990) and the story about Giordano Bruno – “Deep shadow” (1994). There are fragments of them which are shown in “Journal Written at Night” (1985, 1996), and in “Talks in Dragonea” (1997) – between Herling and Bolecki.Key words: Giordano Bruno; Caravaggio; Gustaw Herling-Grudziński;
