Slowly, more examples of monuments based upon counting emerge. In both the monuments and (incredibly rare) art preserved within the Gavrinis Cairn, there is evidence of how megalith builders handled numbers to resolve counts as lengths made up of repeated aggregate units. One hopes that counting and its associated number science of metrology and geometry, will eventually be seen as the powerful yet simple astronomical technique complementary to the known alignment of monuments to key horizon events, between which such counts were made.
In Thornborough one notes the technique of scaling using the foot of twelve inches to provide a twelve-times larger version of a time period than that available inside the central henge. One sees the common composition and scale of North Yorkshire's henges, and finds dimensionality can restore some meaning that has survived the ravages of time upon this great earthwork. There is insight into a little known periodicity of 144 lunar months which proves related to the moon's nodal period in the ratio 5:8 and this allowed the monument to count the 6800 days in the nodal period, explaining the form of triple henge as of the lunar maximum and minimum standstills, and the time in-between these horizon events, the monument pointing to the northerly Maximum.
