Dated to the year AD 604; (868.). </p> <p> We clearly see in this woodcut the use of a pseudo-hexagonal background matrix of some sort. This is perhaps an allusion not only to the <a href="http://hexnet.org/content/close-packing-spheres">hexagonal structure</a> of diamond itself, but also to the adamantine nature of hexagonal geometry. </p> Fri, 27 Aug 2010 16:16:19 +0000 https://hexnet.org/content/diamond-sutra-woodcut https://hexnet.org/content/diamond-sutra-woodcut
