Introduction by Nollaig O' Muraile
The work which since the early 17th century has generally gone under the title of The
Annals of Ulster is indisputably the most valuable source for the early history of Ireland
and indeed of Scotland also. Its main value lies in its trustworthiness: it is considered to
have preserved, with an astonishing degree of accuracy, copies of contemporary records
of events dating from as far back as the late 7th century - together with somewhat less
reliable details, based on memory, of matters from some generations previous to that
This faithful reproduction of the original record has allowed linguistic scholars to plot
the evolution of the Irish language through its various phases, from Old to Middle and
on to Early Modern Irish.
The work is also of enormous value for the history of Ulster, and especially the late 15th
century under the direction of Cathal Og Mac Maghnusa, cleric, chieftain and scholar,
who died five centuries ago in 1498. It is therefore appropriate that this, the only
complete edition of the Annals to be published to date, should in 1998 be made available
once more as a memorial to Cathal Og and the scribes and scholars who laboured under
him(particularly Ruairi O Luinn, who penned almost all of the two early manuscript

Annals of Ireland by the Four Masters
On the 22nd January, 1632, this work was undertaken in the convent of Dunagall (Donegal), and was finished in the same convent on the 10th of August 1636.

Although it is just one of several Irish annals, The Annals Of Ireland by the Four
Masters is probably the best known account of ancient Irish history (and the one most
Often referred to). It covers events from the earliest times to 1616 AD. As indicated
above it was completed in 1636, and it is believed to be based largely on earlier historical
records (some of which have now been irretrievably lost it seems). Brother Michael
O'Clery was the chief of the Four Masters employed to compile this major historical


The "Annals of Tigernach" (Teerna), written in Irish with an admixture of Latin, deal
chiefly with the history of Ireland. Tigernach was Abbot of Clonmacnoise and
Roscommon and died in 1088; it is conjectured by M. d'Arbois de Jubainville that his
annals (valuable but meagre) were based on some ancient records kept uninterruptedly
at Clonmacnoise from 544, the year of its foundation.

My apologies for the Gaelic entries. I've not yet found translations. I believe some of these are traceable to the Lords of Massarene and Hy Tuirtre but can offer no verifiable proof. Others would be traceable to the three remaining Septs. If anyone wants to attempt the translations, I would be appreciative of them submitting to our website.
