||The constellation's of Orion and Canis Major both use the same sign for the phonetic Us. As in P-usha and Punar "Vasu" both Ush and Vasu share the same guni root. These constellations were held as auspicious, so many signs came out them? like the phrase Vasu Dvi (two Vasu's)or Deva. The link 29 on the front page or link to the right shows all the signs I found for Orion. The constellation Orion below is actually just to the right of Canis Major. The dictionary below has Ishv-agra thus Agrahayani is the name of the Nakshatra Mrigasiras that is a close match for the sign of a field below the square with four lines going through it (top and bottom seal on the left).The Vedic people used the stars in their dating system and this date became famous Ish-us-tri-kanda the threefold arrow (Orion).
