Last night I read again Machen's "N," for which I posted a link above. (The paintings are mentioned in the very enjoyable, leisurely "prologue" to the main story, btw.) "N" seems to have been written well after the end of World War I, but unless there's maybe one passing reference to automobile fumes, this London story ignores cars. It seems people get around on foot -- as Machen himself seems so often to have done; I don't remember ever seeing that he was a driver. I was reminded of this quotation, which I have cited elsewhere on Chrons: "The volume and depth and intensity of the world is something that only those on foot will ever experience." -- Werner Herzog
That could almost be used as an epigraph for the Machen story, though Herzog has in mind rather more heroic walks than Machen's London rambles.
I found myself wondering about how many of the major fantasists who lived in the era of automobiles either didn't drive much (Tolkien) or at all (Machen? C. S. Lewis? Lovecraft?).
