Archaeologia Volume 34 1851 XIII Orkney Chapter II. But the most considerable of all the antiquities of this district, is the great circle of Stenness, or Ring of Brogar [Map].a. This is a deeply-entrenched circular space, with a diameter of 366 feet, and containing two acres and a half of superficies. No peculiarity is observable in the topographical character of this place. The area is neither level nor smooth, for the natural undulations of the ground traverse the inclosure. Around the circumference of the area, but about thirteen feet within the trench, are single, large, erect stones or pillars, standing at an average distance of eighteen feet apart. These stones appear to be the largest blocks that could be raised in the quarry from whence they were taken, and are without dressing of any kind; hence, their figure is not uniform, and they vary considerably in size; the highest stone was found to be 139 feet above the surface, and, judging from some others that have fallen, it is sunk about eighteen inches into the ground. The smallest stone is less than six, but the average height is eight or ten feet. The breadth varies from 26 to 7'9 feet, but the average is about four feet, and the thickness one foot. No order can be traced in the relative size or figure of the remaining stones; small and large succeed each other indiscriminately. To mineralogists they are known as the flagstones of the old red sandstone formation, and are supposed to have once been mud, which has been aggregated into sub-crystalline forms by molecular forces.
