The star Sirius is the brightest star in the sky, a part of the constellation we know as Canis Major. To our heathen ancestors this star was known as Loki’s Brand, or Loki’s Torch (Lokabrenna), a reference to Loki’s role at Ragnarok, when Midgard will be consumed in a fiery conflagration. It is interesting that this particular star was associated with Loki, and Ragnarok.
