A. Hugh Fisher, Bell's Cathedrals: The Cathedral Church of Hereford
“ CHAPTER II. - THE CATHEDRAL - EXTERIOR. Artistic unity is certainly not the chief characteristic of Hereford Cathedral, but it is doubtful whether the absence of that quality dear to a purist is not more than compensated for by the fine examples of different periods, which make the massive pile as a whole a valuable record of historical progress. And surely it is more fitting that a great ecclesiastical edifice should grow with the successive ages it outlasts, and bear about it architectural evidence of every epoch through which it has passed. ”
