The paper focuses on the apocalyptic elements of the work Arbor vitae crucifixae Iesu by the Spiritual Franciscan Ubertino of Casale. It specifically pays attention to Ubertino’s explanation of the Apocalypse within the historical context where he interpreted certain living persons as bearers of the label of apocalyptic enemies. The paper introduces Ubertino’s concept of the theology of history, presents his source of inspiration, and explains the originality of the concept. Apart from direct quotations from the Arbor vitae, the paper also contains a brief biography of Ubertino of Casale.
