Leabhar Cloinne Maoil Ruanaidh

Leabhar Cloinne Maoil Ruanaidh, or the Book of Mac Dermot, is the title given by Nollaig Ó Muraíle to "a collection of genealogies sometimes referred to as 'The Book of Mac Dermot' ..." which now forms the fourth and most significant part - 'd' - of RIA MS 539 [D i 3].

Outline

A colophon on folio 43r reads A mBaile Mec Aodagain aniu Damhsa, Phillip Ua Duiginain. At the bottom of folio 78v is the following note: Ni bfuaras nisa mho do sheanchas Eirionn acht a mheid do sgriobhamar bhar ndiagh. Leor so an uair-si an seachmadh la do Dhecember, 1644. Mathgamhain O Duibhgeannain.

With this and other evidence - the date 1642 occurs on an earlier page - O Muralies thinks it was written at the Mac Aodagain law-school at Ballymacegan, County Tipperary, before the end of 1644. It also contains additions and corrections by Dubhaltach Mac Fhirbhisigh, especially the O Dubhda genealogies. It is, however, a Clan Ó Duibhgeannáin production.

gollark: If you compare large supercomputers to my phone I think you might be about right.
gollark: Better *how*?
gollark: Oh, flash storage, that is a huge one.
gollark: ... which we *have had*, modern computers are better than 30-year-old ones.
gollark: So, say, OLEDs, capacitative touchscreens (okay, I'm not sure how old those are), much faster RAM and new RAM technologies, laptops which you can actually carry, and transistors at the scale of tens of nanometres are not "new technologies"?
