John webb, in his preface to Inigo Jones's posthumously published Stonehenge, in 1655 says : ‘This discourse of Stonehenge is moulded off and cast into a rude Form, from some few indigested notes after the late judicious Architect, the Vitruvius of his Age, Inigo Jones’. Upon these notes, Webb undoubtedly dined not wisely but too well and I trust I shall not be accused of doing the same with Colonel Hawley's many and well digested notes. I have one advantage over Webb in that I have seen Stonehenge, and I very much doubt whether he had.

In describing the stones, I shall begin at the centre and work outwards, taking as centre the point where a line drawn from stone 91 just inside the bank to stone 93, and a line from hole 92 in the middle of the supposed barrow to hole 94 in a similar barrow in the NW quadrant, cut each other and the axis of Stonehenge. It is from this point as centre that all the black circles on the plan are drawn. The axis is a line through the centre, which divides the stones and earthworks into two equal parts.
