Pretty fantastic and glad to have read and learned of CAS. The book is overwhelming in its scope and the size of this man's imagination. He draws each world, each story, each person with incredible depth. An amazing introduction can be found here as well of unusual words. And I think there are few writer's I've ever read that actually put a smell of something awful, the thing you turn your eyes from if you can, that boiling in one's stomach so fully described as to be experienced. His forerunner stories are the sort that always catch my attention (Andre Norton wrote some of my favorites). The deep ideas behind the layers of worlds, the thin veil between them, the unimagined ages and civilizations before ours. The idea of rooms which "exhale a medley of half-forgotten superstitions", poets "regarded as no less anomalous than double-headed snakes or five legged calves", the "vertigo ineffable before the vastness and diuturnity of the cycles of being" - all seem to tell a bit of CAS himself. Where early imaginative books like those of Verne have tried my patience, I found CAS's work to be an impressive collection and a door opened to a early age in this genre, full of "eldritch terrors and forebodings that still murmur in [t]his brain."
