Discovery Civilisation is showing a documentary about the Ark of the
Covenant, suggesting it lies in Rosslyn Chapel's vaults. It was
made in 1997 and is presented by Bruce Burgess. Listed in the
credits is "Mr Niven Sinclair", and though there is much in it
which is correct, it seems to have been drawn from various established
sources including Graham Hancock, Christopher Knight and Robert Lomas,
and indeed Niven's own material.
