In the previous article, it was shown that the form of the trilithons, of five taller double sarsens approximating to a five-pointed star, matches the astronomical phenomena of the successive morning and evening stars, as Venus approaches Earth from the east and then recedes to the west as the morning pass. On approach, the planet rises in the evening sky and then dives into the evening sun and if one traces this motion it have the appearance of a horn. Venus shoots past the sun and reappears in the morning sky as the sun rises, creating another traced horn shape, symmetrical to the evening.

In support of the form of the trilithons resembling five successive double horns of Venus over 8 years, the width of the inner faces can also be interpreted as to their length being one megalithic rod, that is 2.5 megalithic yards. The distance between each pillar is ¼ of a megalithic rod so that, each inner face is divided by 4 of these units which units are 5/8ths of a megalithic yardAny unit of length 2.7-2.73 feet long, after Alexander Thom discovered 2.72 ft and 2.722 ft as units within the geometry within the megalithic monuments of Britain and Brittany., the ratio of the practical year of 365 days relative to the Venus synod of 584 days (365 / 584 = 5/8), the common factor between the two periods being 73 days.

*The combined inner width of each pair of supports would therefore symbolize 8 x 73 days, or 584 days. Five of these pairs would then be 5 x 584 days, which equals 2920 days, this time period also being 8 x 365 days or eight practical years.*

The inner surfaces lie on an ellipse which can be framed by a 5 by 8 rectangle whose sides are exactly the diameters required to form a day-counting circle for 365 day-inches (116.136 inches) and 584 day-inches (185.818 inches). The 365 day-inch circle (shown red and dashed in figure 4) has its centre in the center of the ellipse and so would have touched the two trilithons at A and B, at a tangent to their faces.

The high degree of correlation between,

- the five-fold form of the Venus synod and the five couplets of trilithons,
- the summed inner widths of the trilithons as being 5 x 8 = 40 units of 73 days = 2920 days.
- the out-rectangle of the inner ellipse being 8 by 5 and
- the rectangle’s sides being the diameters of two circles of 584 inches and 365 inches, suitable for day-inch countingThe practice of counting the days, using inches or other small units, between synodic phenomena such as years or planetary loops.,

No other compelling explanation exists, though many interpretions have been proposed such as
