‘In C. S. Lewis’s Narnia books, Aslan the lion represents Jesus. In the most famous of these books, The Lion, the Witch and the Wardrobe, Aslan is slain:
‘“Bind him, I say!” repeated the White Witch … “Let him first be shaved” … the shorn face of Aslan looked … braver, and more beautiful, and more patient than ever. “Muzzle him!” said the Witch … the whole crowd of creatures kicking him, hitting him, spitting on him, jeering at him … They began to drag the bound and muzzled Lion to the Stone Table.’
Later, ‘they heard from behind them a loud noise – a great cracking, deafening noise … The Stone Table was broken into two pieces by a great crack that ran down it from end to end … There, shining in the sunrise, larger than they had seen him before, shaking his mane (for it had apparently grown again) stood Aslan himself.’ Aslan tells them that ‘when a willing victim who had committed no treachery was killed in a traitor’s stead, the Table would crack and Death itself would start working backwards.’
In this imaginative and powerful way, C. S. Lewis shows how Jesus can be both ‘the Lion of the tribe of Judah’ (Revelation 5:5) and ‘a Lamb [that] had been slain’ (v.6).’
