A temporary exhibition that presents Johannes Hevelius as a scholar and an artist while highlighting the ties between the famous astronomer and King Jan III. The historical part of the exhibition focusses on works by Hevelius – illustrated volumes entered into UNESCO’s World Heritage List in 2021, as well as Sobiesciana from the Gdańsk Library of the Polish Academy of Sciences (PAN) and selected objects from the collections of the Museum of King Jan III’s Palace at Wilanów. The Orangery and the historic park of the Wilanów residence provide space for the presentation of graphics, paintings, and installations by members of the faculty and doctoral candidates from the Academy of Fine Arts in Warsaw inspired by Hevelius’ studies of heavenly bodies (including observations of the Moon and the constellations drawn by him). Analysing the visual aspect of the scientific studies of the 17^th-century scholar, contemporary artists staked out an innovative, fascinating path into the limitless space above our heads. The exhibition is the result of a creative exchange between employees of the museum, PAN’s Gdańsk Library, and artists from the Academy of Fine Arts in Warsaw.
