How did the ancient denizen of Stonehenge make use of this famous prehistoric monument ? A new study discuss further evidence that it was a calendar and quite a special one – a 365.25 - day solar calendar similar to others seen emerge in the Eastern Mediterranean , in special in Egypt .
The idea that the traffic circle of Isidor Feinstein Stone is a calendar is far from newfangled but there has been very little concord on how it worked . A routine of solar and lunar calendars have been proposed to explain the organization of the Sarsen , the proficient name for the standing stones . The stones are oriented towards the dayspring of the summer solstice , hence the solar connexion .
The study , issue in the journalAntiquity , argues that the Sarsen circle was made of 30 Harlan Fisk Stone , each representing a day of the month , which was divide into “ weeks ” made of 10 mean solar day and marked by anomalous rock . Twelve months of 30 days make 360 Clarence Shepard Day Jr. . The final five days to make out a solar year were mark using the five structures of the Trilithon Horseshoe , which are settle conspicuously in the center of the memorial . Thanks to the four post stones located outside , an extra day could be added every four years .

The mapping of this calendar would not have been to say " today is Wednesday , March 2 , 2022 atomic number 58 " or even to separate farmers when to embed their seed or when to harvest their crop . The function of such a massive calendar would be to notice the important festivity , the festivals of those masses .
“ The calendar is there so that thing happen on the days that the gods rule . Or turn it around , they are there when the god is there waiting to be conciliate , ” author Professor Timothy Darvill , from the University of Bournemouth , tell IFLScience . “ It is that relationship between the universe and the day - to - day life of the everyday the great unwashed , which is why a calendar is an important part of that . And the masses who control time are the multitude who check the deities . ”
A 365.25 days solar calendar is awfully intimate and it brings forth the question , assuming that the rendition is correct , of where this idea came from . Darvill suggest that it was imported to Britain as people act across Europe .
“ That pattern is one that we can see in other parts of the honest-to-god domain at the same meter as Stonehenge is being built . It ’s often referred to as the Egyptian Civic calendar although it was used well beyond Egypt , ” Professor Darvill explained . “ That calendar , of track , became the ground for a pile of the modernistic calendar that we have occur to use . ”
Around the prison term of the construction of Stonehenge , solar religious cult pass around across Europe arise from the Egyptian cultus of Ra . Thanks to mobile cultures originating in the Mediterranean , theme spread and something like a calendar might have made it all the way to Britain . In the last 20 year , ancient DNA has shown that multitude really did move about .
“ Stonehenge is a very long - lived and complicated memorial . Deciphering it is unmanageable . And it is great that there is a lot of work run on in that area just at the moment , ” Professor Darvill proceed . “ It ’s like a peachy chivalric cathedral or a great shrine from any religion … These buildings , these structures have a life of their own , and they exchange over the course of time … But at the destruction of it is not the construction that is important , it ’s the people who are in the construction … They work up a monument to do something with . ”
