    Bound lodestone
    From: Paul Saffo
    Date: 2011 Jul 19, 12:23 -0700

    I have a much-loved silver-bound lodestone on my desk (pic attached). It is unusual in that it is engraved with a name and date ("G. Denning 1791") under the iron keeper on the top, which based on the quality of the engraving, I suspect was the name of the owner.

    While I have read up on the history of the magnetic compass (from gilbert onwards) over the years and of course understand how it was used, etc, it occurred to me that I really know far less about these artifacts than I should.

    I was thus hoping someone on this list might point me towards some more specialized articles?
