Twins in mythology

[2][3] Twins in mythology are often cast as two halves of the same whole, sharing a bond deeper than that of ordinary siblings, or seen as fierce rivals.

This applies to both mortal and immortal sets of twins, and often is related to power over the weather.

This phenomenon is a very common interpretation of twin births across different mythological cultures.

[5] This etymologically explains why their constellation, the Dioskouroi or Gemini, is only seen during one half of the year, as the twins split their time between the underworld and Mount Olympus.

In an aboriginal tale, the same constellation represents the twin lizards who created the plants and animals and saved women from evil spirits.

Without the creation of the doll, the living twin is almost destined for death because it is believed to be missing half of its soul.
