 The motif of warriors competing for the champion's portion is found in another Ulster Cycle tale, "Scéla Mucce Maic Dathó" ("The Tale of Mac Dathó's Pig"), and is reminiscent of descriptions of customs of the Celts of continental Europe as recorded by classical authors.The beheading challenge also has classical parallels, and also appears in later medieval literary works like "Sir Gawain and the Green Knight".
