a plain circle (L) 33 or 34 feet in
diameter, composed of twenty-eight stones. The space within them is
filled up with earth to form a raised platform. At a distance of 75 feet
are two concentric circles, diameters 155 and 184 feet respectively,
made of stones 5 or 6 feet high. The space between the two circles is
filled with earth. Within these is a third concentric circle about 48
feet in diameter made of stones of the same size. This group of three
concentric circles we will call M. The line joining the centres of L and
M runs in a direction of 29 deg. or 30 deg. west of north and passes through a
stone (N) 8 feet high standing on the top of a ridge 2500 feet away.
There are two other stones more to the west (O and P) in such a position
that the line joining them (41 deg. west of north) passes through the centre
of M, from which they are distant 860 and 1450 feet respectively.
Further, a line through the centre of L and a great standing stone (Q)
2480 feet from it in a direction 10 deg. east of south passes through the
highest point in the district, 1615 feet away and 492 feet in height.
Mr. Lewis compares this group of monuments with that of Stanton Drew in
Somersetshire. In both a line joining the centre of two circles passes
through a single stone in a northerly direction, and there is in both a
fixed line from the centre of the larger circle. Captain Boyle
Somerville, R.N., finds that the line 29 deg. or 30 deg. west of north would
mark the setting of Capella in B.C. 1600, or Arcturus 500 B.C.; he adds
that the direction 41 deg. west of north would suit Capella in 2500 B.C. or
Castor in 2000 B.C.
On the west side of Lough Gur is another group of monuments. There is in
the first place a circle 55 feet in diameter. On a line 35 deg. east of
north from this is a stone 10 feet high, and the same line produced
strikes a prominent hill-top. Somewhere to the south-west of this
circle, perhaps with its centre in the line just described, lay a second
circle between 150 and 170 feet in diameter, destroyed in 1870. Three
other stones mentioned by early writers as being near the circles have
now disappeared. The direction 35 deg. east of north is the same as that of
the King-stone with regard to the Rollright Circle in Oxfordshire. This
line, allowing a height of 3 deg. for the horizon, would, according to Sir
Norman Lockyer, have struck the rising points of Capella in 1700 B.C.
and Arcturus in 500 B.C.
