<p dir="ltr">Background: ‘Radiant Systems: Threshold Fields’ (37PK Haarlem, 2025) was an international invitation developing work for ‘The LeWitt Tapestry Suite’. Drawing on the Chester Studio, the exhibition investigated radiant thresholds where figuration and abstraction, intuition and analysis converge. Central was the exploration of sequence, serialisation, repetition, and reversal between duets as architectonic states in the Chester studio. </p><p dir="ltr">Research Question: ‘How can radiant thresholds, re-sited through LeWitt’s studio legacies, operate as material-intuitive zones where figuration/abstraction and intuition/analysis coalesce, generating processes that culminate in a three-layered, light-emitting tapestry?’ </p><p dir="ltr">Significance: ‘Radiant Systems’ reframed personal languages as radiant sequences and duets, establishing thresholds as active knowledge fields. Engaging David Areford's ‘Locating Sol LeWitt’ it positioned the studio as both geographic anchor and knowledge structure where process itself produces outcomes. By embedding Jewish and Christian traditions within systemic possibilities, the project advanced ‘Radiant Systems’ as a theological inquiry also, opening new ground for global LeWitt studies. Contribution: The exhibition comprised nine works in drawing and installation, with ‘Radiant Reversals’ as the central piece. Engaging LeWitt’s Jewish heritage in dialogue with Christian iconography, it positioned reversal as both method and metaphor. Developed during the Haarlem residency, the series employed colour, folded paper, tape, thread, and light-based sequences to test threshold possibilities. The project reimagined the “threshold” not as boundary but as radiant field, producing a transferable methodology for material abstraction. Linking LeWitt’s Chester Studio to contemporary contexts and extending research from ‘The Tapestry of Light’, it generated new knowledge fields in the thresholds within LeWitt’s legacies.</p>
