Nephilim Sun Temple 666 Feet in Circumference in Madison County, Kentucky

This map of the two henges at the Bogy Mill was originally published in The Prehistoric Men Of Kentucky by Colonel Bennett Young in 1910. The smaller henge has a circumference of 450 feet and the larger was reported at 663 feet. The larger was more likely 666 feet and Young gave it a more benign measurement.

666 was the Gematria numerology codex for the Sun. Gematria was developed by the accounted giant race in the Bible called the Amorites. More on Gematria numerology within the Ohio Earthworks here https://www.mysteriesofancientamerica.com/2020/07/amorite-babylonian-numerology-at-adena.html

The Prehistoric Men of Kentucky, 1910

The best types of these circular enclosures are found in Fayette, Montgomery, and Madison county(s). Silver Creek, in Madison County, seems to have been a favorite place not only for the construction of mounds for habitation, but also for the erection of enclosures and ceremonial structures. Three of these can be found within a distance of three miles on Silver Creek—two of them on the land of Mrs. Fred Ferris, eight miles from Richmond, near a post office called Ruthton. They are both remarkable products of the prehistoric age, and one of them is practically untouched and uninjured. These two structures lie on the north side of Silver Creek, and with the exception of the circular enclosure on the North Elkhorn in Fayette, there is no earthwork better preserved in Kentucky than the small one of these. It was built on the spur of a hill coming down toward Silver Creek and nine hundred feet from the water line, with an elevation of probably fifty feet above the stream. On the west side was a steep slope, on the east side another slope, while on the north side it was only lifted about four or five feet above the original surface, and on the south side there was a descent to silver Creek.

Squire Boone, a brother of Daniel, in passing down Silver Creek noted the fine location of this particular point for a mill site, and told his companions it would be one of the best of such sites in Kentucky. In the early pioneer days a mill was erected by James Bogy at this place. He patented the land and died some time early in the Nineteenth Century, and chose the middle of the smaller of these structures for a family burying-ground. The larger structure consists of an embankment six hundred and sixty-three feet in circumference, inside of this moat or ditch. The height of the embankment has an average of four feet, the ditch a depth of from four to six feet. The width of the wall at the base is thirty-six feet, the width of the ditch forty feet. This ditch had evidently been filled up several feet by decaying vegetation and by erosion. The diameter of the inside plateau, or space surrounded by ditch, is one hundred and thirty-five feet. These structures are only about four hundred feet apart. The second is smaller but retains its form more perfectly, and is splendid demonstration of the symmetry with which these enclosures were laid out. It consists of an earthen embankment thirty-six feet in width. Inside of it is a ditch twenty-one feet wide, with a present depth of ten feet. The circumference of the embankment is four hundred and fifty feet. Inside of the ditch is a raised spaced with a diameter of seventy-five feet. This is covered now with a perfect sod of bluegrass, and trees are growing upon it, which show an age of one hundred and twenty-five years. The Bogy family, who patented this land, recognizing the splendid situation of this prehistoric structure and the symmetrical form of the plateau inside the ditch, with its seventy-five feet of diameter, appropriated it for a family burying-ground. These burials began in the Eighteenth Century and continued down to 1850. Every available space in the circle has been occupied by these intrusive burials. White and colored pioneers were here laid side by side. […]

North of Mrs. Ferris's place, about three miles farther down Silver Creek, is another of these enclosures, almost a counterpart of the two previously described.

This is an aerial from Microsoft Terra Server of the remaining smaller Bogy Henge. I was unable to access the site for a ground-level photograph because the drive back to the circle was gated. According to Kentucky law, if a member of the Bogy family asked that this graveyard be accessible, the owners of the property would be required to keep the gate open. The location of the Bogy circle is a half a mile east of Ruthton.
