At Áspero a circle of stone: archaeologists read an observatory of the Caral culture

In the ancient coastal settlement of Áspero, in Peru, a complex of circular stone platforms has been identified that archaeologists interpret as an early astronomical observatory. The site is associated with the Caral culture, one of the oldest civilizations of the Americas, which flourished between 3000 and 1800 BC. If the interpretation holds, this would be one of the oldest sky-observation devices on the continent.

The interesting part, however, is not archaeoastronomy in itself, but the function attributed to it. According to the archaeologists’ reconstruction, observations of the sun, moon and stars served a very concrete economy: anticipating seasonal changes, scheduling fishing trips, managing coastal resources. Not a temple of the sky, then, but a planning tool. A settlement that lives off the sea needs to know in advance when the sea changes, and the sky is the only calendar available.

Regarding this research it must be stated clearly that the news currently comes from a single source (the July-August 2026 issue of Archaeology Magazine, which reports on the excavation research at Áspero); no independent confirmation available. Interpreting a structure as an observatory is, by its nature, a functional reading that requires further verification: the platforms are a fact, their intended use is a hypothesis of the excavators.

Thousands of kilometers away, the Regional Archaeological Museum of Plovdiv is practicing an exercise in transparency that would deserve more imitators. From August 11 and until the end of the year, the exhibition “Discoveries 2025 – Threshold Between Worlds” is open, dedicated to the most significant finds of the latest excavation season in the city and the surrounding region. The exhibition path is built around two poles of ancient societies’ life: daily existence and the afterlife.

The format — a museum that every year displays what it has just found, without waiting for the definitive scientific publication — radically shortens the distance between excavation and public. Here too a clarification: the news currently comes from a single source (the Bulgarian agency BTA, which reports on the Plovdiv museum); no independent confirmation available.

The third case is Parisian and concerns another idea of artifact. The Musée Maillol is hosting, until October 31, 2026, the “Gianni Versace Retrospective,” presented as the first major French retrospective dedicated to the designer since 1986. Forty years’ distance between two exhibitions in the same country is a fact that well describes the historically wary relationship between museum institutions and fashion: the garment enters the museum late, and when it does, it is treated as a document.

Three different operations, with the same underlying problem: what do we preserve, and how do we read it. At Áspero the object is a five-thousand-year-old stone structure, and the question is what it was used for. In Plovdiv, they are the fragments of a just-concluded excavation season, arranged according to the division between daily life and the funerary world — that is, according to an interpretive grid chosen by the museum. In Paris, they are twentieth-century garments, which become historical objects the moment they are displayed rather than worn.

In the same Parisian season, the Cité de la Musique is presenting, until August 30, 2026, the new layout of the permanent collection of the Musée de la Musique: a reordering of what one already possesses, which is the least spectacular and most lasting form of museum work.

Anyone wishing to check the three proposals in person has different schedules: end of the year for Plovdiv, October 31 for the Musée Maillol, August 30 for the Cité de la Musique.
