White Lines at Stonehenge Experiment

There is some discussion at Mike Pitt's blog about the source of the white lines seen in old pictures of stones at Stonehenge. See http://mikepitts.wordpress.com/2014/07/17/james-bridges-at-stonehenge/ and for my take on it http://www.sarsen.org/2013/06/white-lines-on-stones-in-old-photos-of.html.

I thought an experiment might be in order.

The white stripes showed up on Stone 56 after Gowland had re-erected it.


Gowland doesn't say if he packed between his "stout timbers" and the stone, but the photo suggests there my have been something placed there.

I have a well lichened Sarsen gatepost, originally from West Kennett, and plenty of stout oak timbers so I have strapped one very firmly to the sarsen and will leave it there for a fortnight to see what happens.



After two weeks I removed the timber and the lichen showed a very small amount of discolouration,


And another two weeks later maybe just a bit more, it looks like lichen has died but it is not conclusive.


I will keep observing.

  1. Well, I guess when you're wrong you're just plain wrong.

    I've been singing about painted stripes on the 5 lintels (and uprights) for a long time, and even had myself persuaded that my comment on Mike Pitts' site last week prompted his latest post on the subject.

    While the interior vertical stripes on L-102 do look like paint, I had never seen the one Tim shows of S-56 after re-erection - and it clearly shows the 'after-image' of the baulking cradles.

    The marks ain't paint, but dead lichen.

    Nice catch, Tim - as usual.

    1. Neil - that is mighty big of you, but I don't think we know the answer yet.
