The minds of stone lovers had colonised stones as lichens clung to them with golden or grey-green florid stains. The human world of stones is caught in organic metaphors like flies in amber. Words came from flesh and hair and plants. Reniform, mammilated, botryoidal, dendrite, haematite. Carnelian is from carnal, from flesh. Serpentine and lizardite are stone reptiles ; phyllite is leafy-green.
