I have suffered wounds in every epoch – wounds from fist and club and rock, from SHELL-STUDDED LIMB and bronze sword, from the mace and the cannon, from arrows and lasguns and the silent smothering of atomic dust, from biological invasions which blacken the tongue and drown the lungs, from the swift gush of flame and the silent working of slow poisons...and more I will not recount!
--quoted from the SF fiction God Emperor of Dune (http://readnovelonline.com/ScienceFiction/God_Emperor_of_Dun...
The speaker, i.e. the God Emperor, was generally listing the wounds arising from kinds of war attacks in history.
I'm not sure whether SHELL-STUDDED LIMB means arms/legs wounded by shells (bullets) or decorated by shells (perhaps sea shells, is there any custom for war in history?). Or anything else?
Thank you!
