The British have King Arthur, who, according to legend, remains aslumber until Britain’s time of need. The Irish have Fionn mac Cumhaill, Ireland’s larger-than-life national folk hero. He too remains aslumber, waiting for the day when his people call upon him for a heroic display, for the vanquishing of some evil foe.

Granted, the people of Ireland might be better off calling on Cú Chulainn, who likely could have beaten Fionn mac Cumhaill in hand-to-hand combat. But look at me, bringing up old news. The whole “Who is the greatest Irish hero of all-time?” question has already been answered. It’s time to move on.

But…in researching this list, it must be said, it did dawn on me that despite the common claim that Cú Chulainn is the greatest hero from Irish mythology, I believe Fionn mac Cumhaill is the most popular hero from Irish mythology. There are more books about him. More folkloric interpretations. More pop culture references.

He’s in Flann O’Brien’s At Swim-Two-Birds. He’s in a Terry Pratchett / Steve Baxter novel (The Long War). He’s a ghost who makes magic beer in Tim Powers’s The Drawing of the Dark. Heck, Fionn appears in James Joyce’s Finnegans Wake. What’s more, some believe that the novel’s namesake, the Irish street ballad “Finnegan’s Wake,” is a conflation of “Finn again is awake,” a reference to Fionn mac Cumhaill’s eventual awakening to defend Ireland. But I digress…

Fionn is a complex character in Irish storytelling who exists as two distinct personages. First, there is Fionn mac Cumhaill of the Fenian Cycle of Irish mythology. He’s a third-century hunter and the leader of the Fianna, a band of warriors tasked with protecting Ireland. Then there is Finn McCool, the giant from Irish folklore who created the Isle of Man and the Giant’s Causeway while tossing chunks of rock and clay at a rival Scottish giant.

How do we account for such wild swings in character? To quote famed Irish poet W. B. Yeats:

“When the pagan gods of Ireland–the Tuath-De-Danān–robbed of worship and offerings, grew smaller and smaller in the popular imagination, until they turned into the fairies, the pagan heroes grew bigger and bigger, until they turned into the giants.”

The 12 Best Books About Fionn mac Cumhaill, the Fair One, Leader of the Wild Hunt, Chieftain of the Fianna

1) Fionn mac Cumhail: Celtic Myth in English Literature (Irish Studies)

by James MacKillop

Per the publisher: “Stories about Fionn and his warriors continue to be told by storytellers in Ireland and in Gaelic Scotland to this day. This book traces the development of Fionn’s persona in Irish and Scottish texts and constructs a heroic biography of him. As aspects of the hero are borrowed into English and later world literature, his personality undergoes several changes. Seen as less than admirable, he may become either a buffoon or a blackguard. Somehow these contradictions exist side by side. Among the writers in English most interested in Fionn are James Macpherson, the ‘translator’ of The Poems of Ossian.” Learn more…
