This article discusses the Franciscan theme in Polish literature, which was apparent from the 19th century onwards, and especially towards the end of that century. This trend involves the works of many authors and an enormous variety of texts. Therefore, this article focuses on two writers—Józef Wittlin and Roman Brandstaetter—who clearly inherited the broad Franciscan tradition, and also developed and popularised the Franciscan message. The Franciscan revival in Polish literature was initiated by Protestants, which often meant a departure from the figure of St. Francis established by the Church in favour of an individual understanding and presentation of him. The first Polish centre of the revival of Franciscanism as a literary and cultural formation was Lviv. Józef Wittlin grew up in this environment; moreover, he authored, inter alia, the first Polish unfinished novel about St. Francis Salt of the Earth, which refers to Franciscanism, as well as a number of smaller texts with a Franciscan message. Wittlin was a mentor to Roman Brandstaetter, who, after World War II, became the greatest bard of Assisi and St. Francis in Polish literature. Unlike Wittlin, who was Protestant-inspired, Brandstaetter clearly placed the Assisi saint in a Catholic context. This writer greatly expanded references to Franciscan tradition and art in his work. He wrote essays on Assisi, wrote a drama about St. Francis, and combined Franciscanism with biblical themes, as evidenced by his Jesus of Nazareth tetralogy. Despite their differences, what both writers shared is that the saint from Assisi was neither an object of devotional worship nor an outdated figure, but a representative of ideas and layers of spirituality that had remained fresh for people living in that conflicted era. Although they emphasised other aspects of the Franciscan ethos, they both accepted it as a counterbalance to a cold and indifferent world, an idea for living addressed not only to Christians, but also to people of other faiths and agnostics.
