In 1872 antiquarian James Fergusson wrote: "What, then was the object of this great earthwork with one solitary dolmen in the centre? Was it simply the converse of such a mound as that at New Grange? Was it that, instead of heaping the earth over the sepulchral chamber, they cleared it away and arranged it round it, so as to give it dignity? Or was it that funereal games or ceremonies were celebrated round the tomb, and that the amphitheatre was prepared to give dignity to their performance? These are questions that can only be answered when more of these circles are known and compared with one another, and the whole subject submitted to a more careful examination than has yet been the case. My impression is that it is the grave of a chief, and of him only, and that it is among the most modern of its class." (Fergusson, James. Rude Stone Monuments in All Countries Their Age and Uses. London: J. Murray, 1872. 229.)
