Big news over the weekend is the discovery of what is being termed the Brazilian Stonehenge (I’d hate to imagine what the Paris Hilton set thinks that is…). From the stories I’ve seen so far (see also here, in which it is a Peruvian Stonehenge), it’s believed that the layout helped pinpoint the winter solstice. It seems more and more obvious that cultures around the world used standing stones for astronomical alignments (Stonehenge, Nabta Playa, and now in Brazil) – an ingrained impulse in humans everywhere, or evidence for a common point of origin? Thanks Kat.
