Bow and Arrow
Throughout mythological writings there are numerous references to arrows in connection with Sirius.
In Hamlet's Mill. de Santillana and von Dechend point out that in many mythologies of the world, Sirius is often the target at which an arrow is aimed. We can therefore interpret Robin Hood's last arrow as representing the departure of his soul, looed off towards the brightest of stars: Erendil's tow Sirius.

The Babylonian name for Sirius was KAK. SI. Dl., which means 'arrow', and the Sumerians, Babylonians, Egyptians, and Chinese all had a constellation built from stars of Argo and Canis Major, which resembled a bow and arrow, in which Sirius was variously either the tip of the arrow or the target.
