"The wayfarer who does not reveal himself and hides himself, but who nevertheless disturbs us... It is beautiful, but I think that any discussion of it spoils it. It is too indescribable: the supper was then depicted in paintings, and we see it in our minds, but even more evocative is the walk at sunset. It is the posthumous episode that touches me most, when Christ enters the house of the apostles, where there is none of the indescribable divinity of the travelling companion of Emmaus. The divinity that you do not recognise, but sense."
