Dr Augustin Lentin, lecturer at Georg Augustus University in Gottingen, spent 6 years studying the copper industry of north Wales in the late 18th century, the greater part of that time in Anglesey. During his stay, he sent a series of letters to a friend in Germany, relating the history of the island, before going on to describe in some detail, the industrial processes which he claimed, produced copper of a purity then not capable of being produced in his homeland. On his return to Germany, he was persuaded by his friend to have the letters published, and this now extremely rare and important publication, ably translated by Nancy Rothwell, gives us an insight into the workings of what Lentin described as the most productive copper mine existing at that time.
