Yesterday I received this pictures from a friend Jelle Kootstra who went to Italy. He was driving on the 19th of July 2010 in Toscane near Volterra when he saw this pattern in a field. He thought it was a field with oats. He took some pictures out of his car. Volterra is an old Etruscan centre. Maybe someone can check it out.

 

The pattern is referring to the mother of crop circles near Barbury Castle in 1991!
