Note 9 — Chapter I · INTRODUCTION

“Circles form another group of the monuments we are about to treat of.... In France they are hardly known, though in Algeria they are frequent. In Denmark and Sweden they are both numerous and important, but it is in the British Islands that circles attained their greatest development.”—;Fergusson, J., Rude Stone Monuments, p. 47. Referring to Stanton Drew the same authority observes: “Meanwhile it may be well to point out that this class of circles is peculiar to England. They do not exist in France or Algeria. The Scandinavian circles are all very different, so too are the Irish.”—Ibid., p. 153.
