An excellent sentence

"It savored of the wildest dreams of myth-maker and theosophist, and disclosed an astonishing degree of cosmic imagination among such half-castes and pariahs as might be least expected to possess it."

This is regarding Legrasse's telling of his story of the swamp worshippers in Call of Cthulhu.

I'm just starting to read Lovecraft and this sentence struck me as very cleverly crafted. He doesn't create characters as much as ominous situations that he very expertly describes. His language is good at putting images in my head, and he can also make these zingers that I've quoted above.

Edit: recontextualized the quote
