One of Ireland’s most visited sites, the Rock of Cashel, was in use up to the mid-Eighteenth century. To replace the cathedral there, a new one was built (1749-1784) on the site of a medieval church. The Church of Ireland Cathedral of St John the Baptist now stands next next to an unassuming chapterhouse, which houses the Bolton book collection, which the International Dictionary of Library Histories calls “one of the great treasures of the Church of Ireland” and “probably one of the finest collections of antiquarian books in Ireland outside Dublin.” The Directory of Rare Books and Special Collections (London 1997) says that, “The [Bolton] collection contains many items of great rarity, at least fifty not recorded elsewhere in the world, and some 800 not recorded elsewhere in Ireland.”
Photography is not permitted in the library, but the Heritage Council report on the Library contains images of the interior and of many of the books mentioned below.
The collection includes 11,000-12,000 items. These include fragments of papyrus, 15 manuscripts predating 1701, 45 books printed before 1501 (incunabulas), letters, maps and 200 pamphlets. The oldest manuscript, on vellum, dates from the 12th century and includes an early example of the use of zero. The finest Irish manuscript comes from the hand of Dermot O’Connor of Limerick in 1716, and includes translation of French heraldric rules into Irish. The most notable of the incunabulas is probably an uncoloured copy of the Nuremberg Chronicle (1483).
