More than a mere driver, Laeg serves as Cú Chulainn's confidant, advisor, and trusted friend. His skill with horses and chariots proves essential in battle, while his courage and loyalty match his master's heroism. Laeg travels to the Otherworld on Cú Chulainn's behalf and stands by him until the hero's final moments. In poetry, Laeg represents the faithful companion, the essential support that enables heroic achievement, and the bonds of service that transcend class. He embodies the theme that greatness requires partnership and that true loyalty is itself a form of heroism deserving celebration.

Laeg, Cú Chulainn’s charioteer, possesses supernatural knowledge of roads, fords, and enemies; his loyalty is absolute—he drives Cú Chulainn into his final battle knowing it leads to death; poets may use Laeg to explore companionship, service as heroism, or the witness figure who carries memory; his role highlights the Celtic value of the retinue—no hero stands alone; his detailed descriptions of landscapes in the Táin offer models for ekphrastic or topographical poetry rooted in mythic journey.
