What do these two phases of a new crop picture at Barbury Castle on July 17-18, 2022 show us? 

The geometrical construction used by Archimedes to estimate “pi” in 250 BC, followed by four turns of “arrows” on the next day 

Both new phases were meant to remind us of a four-turn spiral that was coded for pi = 3.141592654, and drawn in the same field on June 1, 2008:  

To understand more deeply, please go to “Archimedes' Approximation of Pi“ (see Archimedes Approximation ) then slide the white oval-shaped button to “6” for a hexagon.
