Fionn mac Cumhail

• Fionn mac Cumhail (earlier Finn or Find mac Cumail or mac Umaill, later Anglicised to "Finn McCool") was a hunter-warrior of Irish mythology, also known in Scotland and the Isle of Man. The stories of Fionn and his followers, the Fianna, form the Fenian cycle, much of it supposedly narrated by Fionn's son, the poet Oisín. The Fenian Brotherhood took their name from these legends.

• Fionn is often portrayed as a giant; Joyce imagined him as a sleeping giant, interred in the Irish landscape, with his head beneath the Hill of Howth (Danish hoved: head) and his toes sticking up at Castleknock.
