Water appears as a direct threat to books, documents and archives, but also as a metaphor for forces that are difficult to control. For JR, the wave evokes climate change, the accelerating development of artificial intelligence and the uncertainty of the future. By freezing it across the building, the artist transforms the imminence of catastrophe into a moment of pause from which to question the permanence of memory and what a society considers necessary to pass on to the future.
The intervention continues inside the Library with «UNDAE», a black-and-white film installed in the Barberini Hall. There, the movement of the waves carries the tension of the façade into a space of contemplation, establishing a continuity between the two works and framing the beginning and end of the exhibition route.
"A lot of my work is about creating bridges. Between institutions, between fear and hope, between old architecture and an impermanent wave."

Curated by Don Giacomo Cardinali, Simona De Crescenzo, Francesca Giannetto and Delio Proverbio, «AQVA» examines the dual nature of water — capable of sustaining life and causing destruction — through a dialogue between the Library’s historic collections and contemporary interventions by JR, typographer Bill Moran, and chef and writer Fulvio Pierangelini.
At the documentary heart of the exhibition are two copies of «Aquatilium animalium historia», published by Ippolito Salviani in 1557 with the support of the Vatican Library itself. They are accompanied by manuscripts, printed books, engravings and objects tracing different historical approaches to the aquatic world, from Apicius’s «De re coquinaria» to travel accounts, marine bestiaries and numismatic pieces.

Bill Moran introduces another interpretation through fourteen works from his «LetterFish» series, in which fish and marine creatures are constructed from movable type, numbers and punctuation marks. The exhibition also presents an original cabinet from the «Typotheca Vaticana» to the public for the first time, bearing witness to the diversity of alphabets historically used by the Vatican Press.

Fulvio Pierangelini completes this intersection of water, culture and memory through six gastronomic narratives inspired by recipes and documents preserved in the Library. The exhibition also includes an installation marking the 60th anniversary of the 1966 Florence flood and concludes with the Conservation and Restoration Laboratory, where water reveals one final paradox: while it is one of the main causes of damage to paper and parchment, it is also an essential tool in their conservation.
«AQVA» will be open to the public from 25 September 2026 to 14 May 2027, inaugurating a five-year programme in which the Vatican Apostolic Library will address the forces capable of endangering memory and, at the same time, transform it into material for interpretation and creation.
