'Katrina Porteous has always kept faith with the North East, where times of transition are intensly played out in the post-industrial landscapes. She refuses to ignore local language either, offering work adept in Northumbrian dialect, modern English, and the argot of science.  Rhizodont considers deep time, extractive industry, alienation, and the efforts of communities to survive with integrity, and, in a crucial act of imagination, she speaks as other non-human entities, an ice-core, a redshank.  We were impressed by the way her attention to the small and local belied the sweep and depth of her project. Rhizodont displays modern lyricism by a senior poet, loving, knowing, and authoritative.' – Kathleen Jamie, Chair of The Laurel Prize 2025 Judges

'Katrina Porteous’s Rhizodont is a polyphonic hymn to England’s North-East coast, burrowing in ‘ware stink / and salty tangle’ as it ranges nimbly across historical timescales and between Northumbrian dialect and scientific discourse. Contemporary dog walkers inhabit the same space as sooty collieries and Scotch gutters; in turn, the recent industrial past fades into the sound of the waves, a blackbird with soil on his whiskers, and the longer and stranger movements of geological time, when Northumberland was a tropical swamp and huge freshwater fish began hauling themselves onto land. Intimate and elegiac as a record of the recent past, Rhizodont is also a dazzling meditation on the relationship between man, nature, and machine.' –  T.S. Eliot Prize 2024 Judges

‘The book is in some ways a snapshot of this moment in time … a snapshot that can be looked back at and say here are our challenges rights now, which is a wonderful thing I think for poetry and for science.’ – Jumoké Fashola, on Rhizodont

'Porteous’s practice feels collaborative and generous, absorbing and interacting with other voices, including those working in other fields: she is a great gatherer and synthesizer of scientific, historical and biographical information. [...] It is easy to be swept along by Rhizodont’s long, thoughtful sequences, which both explore the past and hint at the future.' – Lenni Sanders, The Times Literary Supplement

'... an ambitious, carefully researched and striking account of human responses to historical and prehistorical landscapes and communities that are located on the north-east coast of England. A strong sense of heritage imbues the collection [...] Here there is a real sense of the poet immersing herself in the coastal landscape and letting its deep history express itself in the immediacy of the moment. A meaty and satisfying read.' – Hannah Stone, The Lake

'Rhizodont, Porteous's fourth collection, is a hymn to the Earth, a love letter to the North East. The dialect of Northumberland washes it in a tide of language and, across these shifting sands of words, we step out of time and survey the planet from a geological perspective. The rhizodont of the title, a fossil fish which became extinct 310 million years ago, recalibrates our sense of time and reminds us that the Earth's cycles of erosion, extinction and creation transcend us. The result is a thrilling meeting of ideas and language as Porteous blurs the boundary between man and machine, between planet and technology.' – John Field, TS Eliot Prize reviewer

'Katrina Porteous is that rare, robust perennial bloom, a poet whose lyricism is founded upon clarity of expression and precise attention to the spoken word, whose intellectual sophistication is clothed in simplicity and whose themes are of universal significance, yet rooted in a lifelong commitment to local community and the Northumbrian landscape.' - Mark Cocker (author, naturalist, environmental activist)

'Rhizodont is about survival and extinction within cultures, communities and languages, as well as in the natural world.' – Rowan Bell, The Friday Poem

'Rhizodont does for the mining and fishing communities of post-Thatcher Northumberland what Heaney did for mid century Mid-Ulster, archiving the vast richness of its language, culture and work-lives. Porteous’ painterly eye for detail gives depth and resonance to the histories and dramas of her human and non-human subjects alike.' – Dave Coates, Poetry Book Society Summer Bulletin 2024 (Summer Reading)

‘What are we doing to the planet? What is technology doing to us? These are the common themes, according to the poet herself, within the new collection of poetry by Katrina Porteous, who might well be described as the laureate of the Northumberland coast.’ – Greg Freeman, Write Out Loud

'...this is just stunning. Ideas cover time, deep time - and her deep connections to the place - her place in Northumberland on the north east coast of England. You do not need to know her home to become utterly absorbed in the stories she tells.' - Hugh Warwick (Top 3 Books), Shepherd Books

‘In this collection, images of water and the coastline render tangible the epic making and re-making of the planet, the temporary nature of its creatures and geological features. […] In surreal and urgent ways, Rhizodont imagines the palimpsest of geological history that each landscape holds, unearthing its layers, imparting a sense of wonder at nature’s capacity for reinvention.’ – Tusshara Nalakumar Srilatha, TS Eliot Prize Young Critic

Katrina Porteous has lived on the Northumberland coast since 1987. Many of the poems in her first collection, The Lost Music (1996), explore the Northumbrian fishing community. Her second full-length collection from Bloodaxe, Two Countries (2014), was shortlisted for the Portico Prize for Literature in 2015. Her third full-length collection, Edge (Bloodaxe Books, 2019), draws on collaborations commissioned for performance in Life Science Centre Planetarium, Newcastle, between 2013 and 2016, with multi-channel electronic music by Peter Zinovieff. Her fourth is Rhizondont (2024). She has worked on many collaborations with other artists, often performs with musicians, and is particularly known for her radio-poetry broadcast on BBC Radio 3 and 4.
