Couldn't agree with you more HopHead that, "... ancient monuments exist within the context of their environment...". Your headline of 4 December however read 'Long Man vandalized'. With respect, the Long Man has NOT been vandalized, it is the escarpment several hundred metres to the left of the figure that has suffered grafitti.
This isn't about semantics it's about accurate reporting, without which there's the danger of misunderstanding followed by scaremongering followed by claim and counter claim (something you see in the media everyday).
Would you report that Nelson's Column had been vandalized when it was in fact a case of the walls around Trafalgar Square being daubed with grafitti? Those walls also exist within the context of their (architectural) environment.
