Some years ago there was a significant debate over 'The Roman Invasion of Britain' with regard to whether the aim was Richborough or Chichester.
One of the arguements thrown up regarded the possible knowledge of the tides and currents of the English Channel by the Roman Forces.
There seemed to be a feeling that in 43AD the Romans were somewhat naive about the geography of Britain and the waters around it.
Now we have presented, on BBCs 'Time Watch', that some specific knowledge was well known by those on the continent, at least two thousand years earlier. How could it be that the Romans who must have had, contact for a considerable time with traders and travellers not know about geographical information of places only tens of miles away within the first century AD whilst much further places were comprehended thousands of years previously?
I blame all of this on the destruction of the Library in Aleaxandria, if it had survived we would now not only have the names of those who constructed Rockhenge but also their phone numbers too.
Well they must have had phone numbers..even though whilst getting connected at the telephone exchange they might have got the answer, "Can you hold? I should be able to connect you within the next thousand years.."
