lithogenesis: a collection of pieces pulled from stone, creatures, and rock.

All is lithogenesis – or lochia,
Carpolite fruit of the forbidden tree,
Stones blacker than any in the Caaba,
Cream-coloured caen-stone, chatoyant pieces,
Celadon and corbeau, bistre and beige,
Glaucous, hoar, enfouldered, cyathiform,
Making mere faculae of the sun and moon…
