Terrific blogpost here by Richard Skinner, on how he came to appreciate the poetry of Geoffrey Hill, and also about the joy of discovering a much-sought volume in a secondhand bookshop. Hay-on-Wye, of course, is the best place in Britain for such happy accidents, and the Poetry Bookshop in particular is an absolute treasure trove. I'm long overdue another visit.
My own discovery of Hill's work was somewhat similar. I read a handful of poems, including parts of Mercian Hymns, in a university textbook of my sister's, then read the whole of that collection when I was at university myself – I was trying to dig out stuff for an essay on the 8th century Mercian church, and the computer suggested it in the search.
