The document summarizes legends and myths about twins from various cultures including: - Ainu folktales from Japan about twin sons born from eggs descended from a divine deity. - Udege myths from Northeast Asia about twin brothers who became ancestors of two clans, resembling Ainu origins myths. - Greek myths about the twin brothers Castor and Pollux, who were fathered by different parents (Zeus and Tyndareus) but given partial immortality by Zeus so they could alternate between Olympus and Hades. They became the Gemini constellation.

1. legends about twins, twin cults and the Gemini
From Ainu folktale of twin sons born from eggs and
descended from a divine deity
The Ainu too appear to own a folktale of twin sons
birthed from an egg descended from a god, which
sounds strangely similar to the tales of the Korean King
Suro and other Kaya and Sillan golden egg royal births,

and whose father was a god” — Guide to Carl Etter

Udegey (Northeast Asia) twins, resembles the Ainu clan
origins myth, may demonstrate a common genealogical
tradition of the Northeast Asian Altaic tribes:
“A variant of the myth about the twins—a story of the
two Kamdziga brothers (from the name of birch bark
pannier kamisi) and Sulyaydzinga (from sulaisi—to lie),
who became the ancestors of two clans—is typical. Other
stories reproduce popular beliefs about the life of
Udeges in former times—about crocodiles that used to
be found in the Khor River and monkeys that lived in
taiga. There are traces of influence of other cultures,
perhaps of historical memories of the Jurchens Tungus-
Manchu state (the 12th century). There are stories about
Udeges who used to live as animals, without shelter and
clothing and eating raw meat; about cave dwellers
chased by thunder; about the Ainus who left for
Sakhalin. Ethnogenetic legends relating to telungu
narrate about historical ties of Udeges with neighboring
peoples and between various Udege clans.” — Udege, see

2. also Twin mythology of the Udegeys, distant relatives of
the Ainup
[The Udege – are the most ancient population lived
along the Ussuri River from the Paleolithic and
Mesolithic Age. It consisted of groups that came from SE
Asia. In various periods groups of settlers from the W,
later on from the NW, came here. Local and wider
“multi-layer” culture included remains of previous
cultures. Medieval Tungus-Manchu states of the 8-9th,
12th and 16-17th century also influenced the ethnic
history of Udege. The Udege lang. has both a strong
Evenk layer and elements of the Jurchen, Mongol,
Turkic, Ainu, and Nivkh languages, as well as traces of
some substratum, possibly of Paleo-Asian or Old Korean
origin.]
Greek twins:
Castor and Pollux on a Roman coin

3. Clytemnestra was the daughter of Tyndareus and Leda,
the King and Queen of Sparta. According to the myth,
Zeus appeared to Leda in the form of a swan, seducing
and impregnating her. Leda produced four offspring
from two eggs: Castorand Clytemnestra from one egg,
and Helen and Polydeuces from the other. Therefore,
Castor and Clytemnestra were fathered by Tyndareus,
whereas Helen and Polydeuces were fathered by Zeus.
According to legend, to the dying Castor, Pollux was
given the choice by Zeus of spending all his time on
Mount Olympus or giving half his immortality to his
mortal brother. He opted for the latter (so giving half his
immortality to Castor), enabling the twins to alternate
between Olympus and Hades. The brothers became part
of the stellar constellation Gemini (“the twins”),
becoming the two brightest stars in the
group: Castor (Alpha Geminorum) and Pollux (Beta
Geminorum). As emblems of immortality and death that
were no longer polar opposites, it is not surprising to
hear that the Dioscuri, likeHeracles were said to have
been initiated at Eleusis. The image of the twins
attending a goddess are widespread[10] and link the
Dioscuri with the male societies of initiates under the
aegis of the Anatolian Great Goddess and the great gods
of Samothrace. The Dioscuri are credited as the
inventors of war dances, which characterize the Kuretes.
