Thread Between Darkness and Light, a new photo book by artist Stella Brennan, began with the gift of a painting: a depiction of Rangitoto with a mysterious ruin in the foreground. Investigating its painter led Brennan to an 1897 photograph of her great-great-aunt Louise Laurent with her female classmates - students at the same art school Brennan attended a century later. Struck by this uncanny affinity with her previously unknown ancestor, Brennan embarked on a journey of research and revelation.

Cold-calling long-lost relatives, she unearthed an archive of Edwardian glass plate negatives, which a cousin had carefully preserved since Louise's death in the 1960s. Despite being cracked and marred by mould and dirt, Brennan meticulously scanned the 300 fragile plates. Her first realisation of Louise Laurent and her husband William Winn's 100 year-old archive was an immersive installation of 36 translucent silk banners, displayed in 2023 at Te Whare Toi, City Gallery Wellington.

This book delves deeper into these historical images, juxtaposing the passage of time with startlingly contemporary framings and content. There is even a string-assisted selfie of Louise and William together. On the other hand, the extreme damage sustained by some of the negatives, the cracked glass, peeling emulsion and blooms of mould speak to the time between then and now. It is this tension that animates the project - this superimposition of time and place. An evocative collaborative essay enlarges the historical and material context. Susan Ballard, Professor of Art History at Te Herenga Waka-Victoria University of Wellington, Kirsty Baker, Curator at Te Whare Toi, and Lissa Mitchell, Curator of Historical Photography at Te Papa, bring their unique perspectives to a text that breathes life into these spectral images.

Brennan's documentation of her discovery process is complemented by historian Ross Galbreath's riveting account of Louise's adventurous mother Lucie, tracing her journey from birth in a London workhouse, to the 1871 Siege of Paris, to her arrival with her three daughters in 19th-century Tamaki Makaurau/ Auckland, Aotearoa/New Zealand. Thread Between Darkness and Light is not just a photobook; it's a poignant bridge across generations, a tapestry woven from the traces of the past into the light of the present.
