A list of a number of the Ulstermen’s exploits forms part of a poem in the
later recension of Cath Maighe Rath which was edited by O’Donovan in
1842 and suggested by Dillon to date from the late-thirteenth or fourteenth
century.1 The earliest copy of the tale is preserved in a portion of the
Yellow Book of Lecan (YBL) written in 1398 9 by Murchadh O´ Cuinnlis
(cols 281-310).2 There are also copies in two seventeenth-century manuscripts
written by Da´ibhı´dh O´ Duibhgeanna´ in and a manuscript of the
early-eighteenth century in the hand of Tumultach mac Muirghiosa, namely
RIA B IV 1 (236), RIA 24 P 9 (739) and RIA 23 K 44 (58), which are
referred to as B, P and K, respectively, below.3 O’Donovan based his edition
on YBL but also consulted the copy in K, adopting its readings on occasion
to correct ‘deficiencies’ where he found the text of YBL to be ‘obviously
defective’.4
