Distance 3 miles from Dolbenmaen, in the way to it, several pillars of different appearance, &c.; none of them equal to those of the grand monument, whose situation is upon the gradual slope of a very high hill, commanding a most extensive prospect, viz. the whole Isle of Anglesey, part of Ireland, &c.
The first object in approaching it is a lonely pillar, distant 160 paces from the grand Ellipsis.
This colonade is in diameter, one way, 44 cubits, the other, 36; consisting of 38 upright stones of various forms, heights & sizes, as well as distances from each other; some turgescent, some flat, some incline one way & some another; some are pyramids & some are cones. The vulgar believe that no one can count them. The area of the monument violated by the plough & harrow &c.
Tradition says that upon one of them being carried away to the adjoining farm house, for a lintel over the door, such a dreadful storm of thunder & lightning ensued, that the sacrilegious hands were forced to return it to its former place. However, the author says that the vacancies shew that several have been carried away, &c.
From Archaeologia Cambrensis, January 1849 (v13), p3. The information is taken from a manuscript from 1772, which 'purports to consist of notes and extracts taken from another work, the title of which is unfortunately destroyed in great part'. Sadly, rather like the circle.
