Mr. Tumnus is a faun — a creature from ancient Roman and Greek mythology that is half man and half goat. Lewis said the whole of Narnia grew from a single picture in his mind: “a Faun carrying an umbrella and parcels in a snowy wood.” He had carried that image since he was about sixteen, and years later it became this very scene. The half-goat, half-human faun Lucy meets steps straight out of Greek and Roman myth, where fauns and satyrs were woodland spirits. Lewis blends such old myths freely — a Roman faun, a Victorian lamp-post and English children together — so Narnia feels like every story at once. The setting places the action in the time and place of a story — a war-time house and a snowy magic wood.

Together, these meanings give the episode verbal precision.

When a story opens a doorway into a strange place, strong readers slow down and notice the sensory details — the crunch of snow, the cold air, the glow of the lamp-post. These details tell us Lucy has truly crossed into another world. Chapter 1 covers Lucy Looks into a Wardrobe — the four children arrive at the Professor’s house; while exploring, Lucy steps into a wardrobe and finds a snowy wood with a lamp-post. Chapter 2 covers What Lucy Found There — Lucy meets Mr. Tumnus the Faun, has tea in his cave, and learns he was meant to betray her to the White Witch, but he sets her free instead. Four children — Peter, Susan, Edmund, and Lucy Pevensie — are sent away from war-time London to the huge country house of an old Professor.

The resulting chain can be read as a coherent sequence.

Lewis builds his opening from three blocks: setting (a war-time house, then a snowy wood), character (curious Lucy and the kindly Faun), and conflict (Mr. Tumnus must choose between obeying the cruel Witch and doing what is right). History — the Blitz & evacuation: in 1939–41, bombing of British cities moved about 3 million people (mostly children) to the countryside under Operation Pied Piper; C.S. Lewis hosted real evacuees. Science — snow & the senses: snow muffles sound because air trapped between the flakes absorbs sound waves — one reason the wood feels so real. Exploring on a rainy day, Lucy hides inside a tall wardrobe and walks backwards through the fur coats into a snowy wood lit by a single lamp-post. There she meets Mr. Tumnus, a Faun carrying parcels and an umbrella.

The chosen technique controls the reader’s viewpoint.

The heart of Part 1 is conscience — the inner voice that tells us right from wrong. Mr. Tumnus is paid to betray Lucy, yet he cannot bring himself to harm a kind, trusting child. The story opens during the Second World War. To keep children safe from German bombing raids on London (the Blitz ), the British government moved hundreds of thousands of city children to the countryside — a plan nicknamed Operation Pied Piper. Lewis really did host evacuated schoolchildren at his own home, which helped give him the idea for four children staying in a big country house. This book contains many allusions (references) to Christianity, because its author, C.S. Lewis, was a well-known Christian writer. In Narnia, humans are called “Sons of Adam” and “Daughters of Eve,” after Adam and Eve, the first people in the Bible’s book of Genesis.

A defensible conclusion requires balanced judgment.
