Cú Chulainn of the Ulster Cycle and Finn Mac Cumhail of the Fenian Cycle are the two early Irish warriors that are most familiar, who have the greatest number of stories told. Many other warriors in the literature boast heroic quests of their own, including the warrior-kings; however, these make up a smaller amount of known literature. There are other warriors known only for their relationships with Cú Chulainn or Finn, as fighting beside them or dying at their hands, while many warriors are only names in long lists. There are also many villains and semi-villains and a, sadly, small number of warrior-women, either protagonist or antagonist.These two heroes have large bodies of material focused on them and what makes them such important heroes compared to the others is of interest.
When they are brought up together, it is often to describe Cú Chulainn and Finn as very different, even opposites. This may have originated from Marie Louise Sjoestedt’s declaration that Cú Chulainn was a “Hero of the Tribe”while Finn was a “Hero Outside the Tribe.”The distinctions Sjoestedt noted may be useful in exploring each of these heroes individually, and they certainly are individuals; however, her designation of Cú Chulainn as a “tribal” insider and assertion that the two warriors’ stories were “irreconcilable” are questionable. Both of these heroes were liminal and quite dangerous to the culture they defended, but were outsiders of. In the different times their tales were recorded, they represent views of those warriors who stood between society and the wilderness, being never fully part of either.
It is difficult in a casual study such as this to sort out what might be similarities due to the nature of the tales and what might be influences of the earlier stories. Cú Chulainn’s tales were written centuries before Finn’s. We do not have evidence that Cú Chulainn’s stories truly come from oral traditions or whether they were told orally after they were written. Both seem likely, at least to some extent. Finn’s stories continued in oral tradition, which gives us even more variations. While knowledge of Cú Chulainn’s stories may have influenced the tellers and writers of Finn’s, the latter are clearly not reproductions. This may be influences of the time, but also may be a hint that they were seen as warriors of a certain nature and place, similar but not identical. Therefore, I believe the comparisons where we find the similarities yet note the differences help us understand the archetype of the Outlaw Warrior in this literature, without losing sight of the individual nature of both Cú Chulainn and Finn.
