‘Most users of these books will have read several of these essays before, but having them in one place is more than a convenience: it allows us to note continuities both within Jennifer O’Reilly’s work (thus making for a more fruitful engagement with her researches) and also to recognize continuities in the artefacts themselves. Moreover, we have not simply been given reproductions of the earlier papers ... but the works have been reset and all the appropriate illustrations have been reproduced in colour — more than 150 in total — close to where they are discussed allowing us to see exactly what is meant in the various iconographical analyses. These sharp, clear colour images, along with two indices, make these books works of scholarship in their own right. We are indebted to the editors for their work for us, as well as for having given us such an appropriate monument to a great scholar’ - Thomas O’Loughlin, Irish Theological Quarterly 2020, Vol 85 (3).‘Everyone looked at the Book of Kells differently when they heard Jennifer O’Reilly talk about it. Her scholarship changed the landscape of the subject’ - Bernard Meehan, Peritia, 31 (2022).
