LONDON.- For its annual Spring commission, Somerset House presents a new multi-dimensional project by Hylozoic/Desires, the cross-disciplinary collective of Himali Singh Soin & David Soin Tappeser. Salt Cosmologies explores the complex weave of histories and myths around Britain’s imperial salt monopoly in India, with a spectacular open-air installation, scaling 80 metres in length and over 2 metres in height and a compelling exhibition set within spaces that once administered Britain’s tax on salt. This will include Somerset House’s Salt Stair, which will open to the public for the first time after an extensive restoration, displaying works specially commissioned for Salt Cosmologies. As Somerset House marks 25 years of its transformation into an international arts destination, it reimagines a historic building for the future with its powerful juxtaposition of inspirational architecture and a centre for contemporary culture.

New large-scale courtyard installation

In the Somerset House courtyard, Hylozoic/Desires present a large-scale installation, entitled namak halal/namak haram (2025). The sculptural work will map out the former Inland Customs Line, a monumental 2,500 mile-long barrier largely composed of vegetation, established by the British in the 19th century to control ‘smugglers’ of salt during its colonial rule of pre-partition India. It was frequently damaged by winds and ultimately succumbed to termite infestations before its abolition, now largely erased from collective memory and the landscape.

The artists’ interpretation of this historical ‘hedge’ is formed of organic cotton fabric hand block-printed by artisans in India with vegetal dyes derived from the original plants from the hedge, fixed with salt. One side showcases colonial-era botanical drawings in a meticulously organised, grid-like format, while the opposite side contrasts this with an unrhythmic, disordered stamping of the phrase ‘Salt Issued’, inspired by historical receipts. This is overlaid and overwhelmed by a contrasting print of an emblem of a termite, rendering it illegible. The title of the installation ‘namak halal’ (in accordance with salt, a term used to describe a loyalist of the British Empire) and ‘namak haram’ (against the salt, a traitor of the Empire) equally highlights the hedge's dual nature as both an instrument of colonial extraction and a site of resistance to colonial occupation, as ideas of liberation were smuggled through and over the British-built barrier.

Salt Stair Restoration and Terrace Room

Salt Cosmologies continues in the South Wing of Somerset House in spaces that once held the offices which administered Britain’s colonial-era taxes on salt, allowing the public to revisit the entangled histories of salt in a site-specific setting.

The Salt Stair will open to the public for the first time after an extensive restoration. For the duration of Salt Cosmologies, the stairs will display a series of prints visualising the so-called ‘Great Salt Hedge of India’. Whilst scouring the archives for Salt Cosmologies, Hylozoic/Desires only found textual descriptions of this monumental hedge. With these descriptions as prompts, they generated imagery using AI and printed the works using a Victorian-era salt-print process. These speculative prints will sit alongside real-life photography of Sambhar Lake, an important British outpost for the harvesting of salt. Presented alongside the prints is Namak Nazar (white noise), 2025, an immersive soundscape, created by using salt itself as an instrument. Continuing down the stairs, visitors will have the chance to view The Phantom Line, 2025, a video work that documents the artists on a journey tracing the ghostly remnants of the Inland Customs Line today.

Documents on display in the Terrace Room will further detail the history of the hedge, with archival material including: an original Salt Tax License receipt from 1890, showing a transaction of Salt under colonial taxation rules in India; the iconic image of Mahatma Gandhi picking up a lump of salt at Dandi in 1930 and a telegram from the Governor of Bombay describing the scene. The exhibition also features historical botanical drawings and specimens, showcasing the plants and wildlife which made up the hedge including dried fruit and wood of Acacia Catechu, Prickly Pear, Madras Cochineal and Karwand roots, as well as bird skins of the White-eared Bulbul and Variable Wheatear. The specimens highlight how salt, a common and naturally occurring mineral and the hedge, a largely natural barrier made up of native species and thorny shrubs, were weaponised during the colonial era.

Salt Cosmologies is part of a series of related presentations by Hyzoloic/Desires, including The Hedge of Halomancy, a film installation exploring the story of the hedge and the characters who passed through it, at Tate Britain (February 27 to August 25, 2025) and 16th Sharjah Biennial (February 6 to June 15, 2025).

Salt Cosmologies is curated by Cliff Lauson and Kinnari Saraiya.
