The landscape descriptions in the ‘Commentarii’ of Pius II represent a characteristic element of this autobiographical text. One might ask whether his depictions of nature stem from own experience and encounters, or whether the landscapes depict a fictitious and literary world and are thus a construct of a humanist whose text abounds with classical citations. The following article addresses this topic from two directions. On the one hand the Pope’s physical presence in the open landscape is verified through reference to (...) other sources; on the other hand his specific way of perceiving and describing nature is investigated. The letters of his entourage and the dispatches of diplomats do show that excursions took place as described by Pius, and that the journeys of this gout-ridden pope even into impassable areas convinced them of his love for nature. Pius’ companions affirm, often with a certain critical distance, his intimate bond with the landscape; they speak of picnics on the banks of a brook rather than in the neighbouring villa, of work-sessions in the forest instead of the palace, and of spectacular views from arduous mounted heights. All of this implied a logistical organization on the part of the courtiers, to which they were not accustomed. Pius’ description of views both near and far, and his desire to be in the midst of nature attest directly to a certain feeling characteristic of the early Italian Renaissance feeling, an epoch whose art too perceives landscape in a new form.
