The Great Parchment Book of The Honourable The Irish Society is a major survey, compiled in 1639 by a Commission instituted under the Great Seal by Charles I, of all those estates in Derry managed by the City of London through the Irish Society and the City of London livery companies. It represents a hugely important source for the City of London’s role in the Protestant colonisation and administration of Ulster. Damaged as the result of a fire at Guildhall in 1786, it has been unavailable to researchers for over 200 years. However, the manuscript has remained part of the City of London’s collections held at London Metropolitan Archives (LMA reference CLA/049/EM/02/018.) As part of the 2013 commemorations in Derry of the 400th anniversary of the building of the city walls, it was decided to attempt to make the Great Parchment Book available as a central point of an exhibition in Derry’s Guildhall.
Physical description and issues
The manuscript consisted of 165 separate parchment pages, all of which suffered damage in the fire in 1786. The uneven shrinkage and distortion caused by fire had rendered much of the text illegible. The surviving 165 folios (including fragments and unidentified folios) were stored in 16 boxes, in an order drawing together as far as possible the passages dealing with the particular lands of different livery companies and of the Society (see Book History.)
