In Rosemary Sutcliff’s classic children’s novel The Eagle of the Ninth, the protagonist Marcus and his friend Esca (freed from slavery by Marcus) travel to the wild lands of Caledonia (northern Scotland) to search for the lost Eagle of the Ninth. On their travels, they pass through many mountain ranges and lochs. One of these Mountains is Ben Cruachan, the highest point in Argyll and Bute.

And to the north, brooding over the whole scene, rose Cruachan, sombre, cloaked in shadows, crested with mist; Cruachan, the shield-boss of the world.
