Arthur Machen(1863–1947)
Strange Roads (Sketches by Joseph Simpson, R.B.A.)
And
With the Gods in Spring (Sketches by H. R. Millar)
Limited Edition, (1923).

Two stories with a common theme: that landscape can affect our sensibility; and that ancient landscape can evoke a sense of the numinous.

I found the text and the illustrations by working on a pdf from The Internet Archive.
