The sentence "The Fauns footed it all round Caspian to their reedy pipes" is likely from C.S. Lewis's "Prince Caspian" and describes a scene where Fauns, mythical creatures with the body of a human and the lower body of a goat, dance in a circle around Caspian while playing music on their reed pipes. This imagery creates a celebratory and magical atmosphere, characteristic of C.S. Lewis's whimsical writing style in the Narnia series.
