The text breaks off while Fionn investigates a "sídhe" or fairy mound, before his trip to Tara. Scholars have pointed out similarities between earlier versions of "The Boyhood Deeds of Fionn" and tales of the youth of the Ulster Cycle hero Cúchulainn. For instance, "The Boyhood Deeds of Cúchulainn" and "The Wooing of Emer", both found within the epic "Táin Bó Cúailnge", recount Cúchulainn's earning of a nickname through his feats, his training by a warrior woman (Scáthach) and his earning of a deadly spear (the Gáe Bulg).
