We all know that as manuscripts were copied over and over again down the centuries that errors crept in. This didn\’t go away with printing….there\’s one Bible that was printed declaring \”Thou shalt commit adultery\”.
Unfortunately it still happens:
There was a belief among miners that it was unlucky to eat the thick crimped crust and it should be thrown to the ‘knockers’ (the spirits of the tin mines).
There was also a practical benefit.
Miners used the crust as a handle to hold the pasty while they ate, so avoiding transferring arsenic, a deadly poison present in the mines, on to their food.
While there was arsenic in the Cornish tin ores that\’s not quite the thing that people had to worry about: actinic acid was.
