This is a very interesting 2017 short talk from Katy Whitaker on the nineteenth-century (and early twentieth century) sarsen stone cutting industry in Buckinghamshire and Wiltshire:
Well worth watching. She describes how the industry moved from Buckinghamshire (where the sarsens were largely underground, and had to be quarried out of deep pits) to Wiltshire (where the sarsens were available in profusion on the ground surface. She gives some interesting detail on how the stones were split into rectangular blocks, using the well-known wedge and feather(plug and feather) technique. This is of course the technique that Prof Mike Parker Pearson and others have suggested as having been used at Rhosyfelin and Carn Goedog..........well before the advent of metal tools........
Since we are on about silicosis, her talk title is very suggestive. But she does not spend much time on this aspect, apart from mentioning that the two entrepreneurial brothers who started the business of sarsen stone recovery and cutting both dies of silicosis at an early age. I would have liked more on this, but in 18 minutes she did pretty well to pack in as much as she did. She mentions the abundant failures and the decline of the industry because of economic factors, but does not really explore the extent to which the industry was vulnerable because of the high attrition rate in the work-force, with stone cutters maybe going down like ninepins because of lung disease........ and others reluctant to go into the industry because of the perceived health risks.
But this re-focuses our attention on the idea that silicosis could well have been an issue for the builders of Stonehenge.
