Here’s Why the Venice Biennale Main Show Lost One Artist During the Planning Stages

The Venice Biennale's main exhibition, curated by the late Koyo Kouoh, originally included 111 artists when announced in February, but now lists only 110. ARTnews reveals that the removed artist is Bodys Isek Kingelez, a Congolese sculptor known for his colorful cardboard "extreme maquettes" of fantastical cities. A Biennale spokesperson stated that works initially considered for Kingelez were ultimately unavailable. Kingelez, who died in 2015, was to be one of the few deceased artists in the show, alongside figures like Marcel Duchamp and Issa Samb.

New York art world spared worst of logistics woes

New York's spring art fairs—including Frieze, Tefaf, Independent, and Nada—are proceeding largely on schedule despite ongoing disruptions from the war in Iran. Airspace closures, reduced flights, rising fuel costs, and the closure of the Strait of Hormuz have strained global art logistics, forcing rerouting, last-minute cancellations, and cost increases of up to 2,500%. Logistics firms like Hasenkamp and Gander & White report that while shipments are still arriving, the system has become fragile, with clients prioritizing safety and resilience over speed.

Most famous image of JMW Turner not a self-portrait, says expert

Dr James Hamilton, a leading Turner expert, has claimed that the most famous portrait of JMW Turner—long believed to be a self-portrait and featured on the UK £20 banknote—is actually by the painter John Opie. Hamilton argues that the work, dated around 1799, was mistakenly included in the Turner Bequest after the artist's death in 1851, when his studio was in disarray and the attribution was never properly verified. He points to stylistic evidence, including Opie's characteristic use of dramatic light and shadow, and calls on Tate Britain to reattribute the painting.

Dark clouds, protests and resignations dampen start of 61st Venice Biennale

The 61st Venice Biennale opened under grey skies and rain, with political tensions overshadowing the art world's premier event. The Russian pavilion, absent for two editions due to the Ukraine war, reappeared with a party atmosphere, though the Italian ministry of culture confirmed it would not be open to the public. The Ukrainian culture minister called Russia's symbolic presence powerful. The Iranian pavilion withdrew without explanation, and a protest by 60 artists from the In Minor Keys show marched through the Giardini humming in solidarity against Israel's participation. Over 200 artists, including Lubaina Himid and Alfredo Jaar, signed an open letter demanding the Israeli pavilion's cancellation. The event also proceeded without its curator, Koyo Kouoh, who died in May 2025; her curatorial team delivered the exhibition following her plans.

What It Takes to Build the Venice Biennale

Three weeks before the Venice Biennale opens on May 5, the city remains a construction site, with the Giardini closed and parts of the Arsenale requiring special access. Artist Faustin Linyekula rehearses his performance *The Galeazze Project* in a 16th-century roofless complex, working with the existing gravel, natural light, and lagoon acoustics rather than imposing a structure. Geopolitical conflicts, supply chain disruptions, and the sudden resignation of the Biennale’s international jury via Instagram add pressure to the already challenging logistics of mounting the global exhibition.

Seen in Venice, Bought in Venice

"In Venedig gesehen, in Venedig gekauft"

The article reports on multiple developments surrounding the Venice Biennale. Iran has withdrawn from the Biennale, citing political and economic crises, with logistical challenges such as no flights or postal service making participation nearly impossible. Artist Anish Kapoor has called for the exclusion of the United States from the Biennale, criticizing its "abhorrent policy of hate" and "ongoing warmongering." A memorial installation by Derrick Adams for the late curator Koyo Kouoh, who was set to lead the main exhibition, will be displayed near the Arsenale. Additionally, the Biennale faces a funding cut from the EU due to Russia's continued participation despite the Ukraine war, leading to the resignation of the jury and the culture minister's withdrawal.
