Tāwhirimatea, guardian spirit of winds and storms raged at his brothers. How dare they separate his parents after he had told them not to. In his fury he ripped his eyes from his face, shattered them into 1000 pieces and threw them into the sky, creating the star cluster we call Matariki.
Matariki is a shortened version of Mata (eyes) ariki (god) Tāwhirimātea. This special little cluster of stars has enthralled humans for millennia. Every country has its own name and its own myths and stories about these stars.
In Japan they are known as Subaru; you will have noticed the six stars on the back of the Subaru cars. The ancients Greeks called them Pleides, the Seven Sisters. To save them from the hunter Orion, the great god Zeus transformed them into stars. They are featured in the major arcana tarot card, the Star.
One of the biggest myths that I've encountered is that they cannot be seen in Whanganui. They can. Puanga or Rigel rises earlier. We see Puanga first but once we see Puanga we know that Matariki will be following closely behind.
