After the fifteenth century, one gets only sporadic glimpses of the book during the next 300 years. In June 1629 it was deposited in the nearby Franciscan
Timoleague Friary, where the renowned scribe, author and historian, Brother
Mícheál Ó Cléirigh copied material from it. It is thought to be identical to a book confiscated by
Lewis, 1st Viscount Boyle of Kinalmeaky, then aged 23, at the siege of
Kilbrittain Castle in 1642 during the
Irish Confederate Wars, and sent by him to his father,
The 1st Earl of Cork. Lord Boyle of Kinalmeaky (whose younger brother was the chemist
Robert Boyle) died not long after, at the
Battle of Liscarroll in September 1642. , ,
National Museum of Ireland, Dublin It is uncertain when the book was brought to
Lismore Castle in the west of
County Waterford, a castle which Lord Cork had purchased from
Sir Walter Raleigh in 1602. In the eighteenth century, the castle passed by marriage from the Boyle family to the
Cavendishes,
Dukes of Devonshire. In 1814, during renovations to the castle and town of Lismore by
The 6th Duke of Devonshire, the manuscript was rediscovered, having apparently been walled up in the Castle with the
Lismore Crozier, which is now in the
National Museum of Ireland. Upon its discovery, the book was soon loaned to the Cork scribe and scholar Donnchadh Ó Floinn (who named the book 'Leabhar Leasa Móire', the Book of Lismore), whose friend, Micheál Óg Ó Longáin, transcribed nearly all of the manuscript in 1817, under the sponsorship of Bishop John Murphy. The title 'Book of Lismore' or 'Leabhar Leasa Móir' dates from this time. From this and other transcripts by Mícheál Óg, many further copies of sections and individual texts were made, and this contributed to a temporary revival of manuscript-making in Cork during the first half of the nineteenth century. The book was returned to Lismore around 1821–2, but sixty-six leaves remained in Cork, and were subsequently sold to the Duke of Devonshire in 1860. Further transcripts were made by Eugene O'Curry and by Mícheál Og's youngest son, Seosamh, who was by that time employed by the Royal Irish Academy. In 1907, the book went on public display at the
Irish International Exhibition held in
Herbert Park,
Dublin. In 1930, the manuscript was transferred permanently from Lismore to
Chatsworth House in England, where it remained until 2020, except for the years 1939–48 when it was removed to safe storage during the
Second World War and also made available for the creation of the facsimile published in 1950. In 1879, a photographic reproduction of pages from the manuscript appeared, for the first time, in the third fascicle of John Gilbert's
Facsimiles of national manuscripts of Ireland. A printed photographic facsimile, in black and white, of the entire manuscript was made under the direction of R.A.S. Macalister and published in 1950. In 2010, the entire manuscript was digitised by Irish Script on Screen in advance of the public exhibition of the book at
University College, Cork (UCC), in 2011. In 2020, the Book of Lismore was donated to University College, Cork, by the Chatsworth Settlement Trust. The university plans to display it in their Boole Library. ==Further reading==
