... In Hindu legend there was a mother goddess called Aditi, who had seven offspring. She is called 'Mother of the Gods'. Aditi, whose name means 'free, unbounded, infinity' was assigned in the ancient lists of constellations as the regent of the asterism Punarvasu. Punarvasu is dual in form and means 'The Doublegood Pair'. The singular form of this noun is used to refer to the star Pollux. It is not difficult to surmise that the other member of the Doublegood Pair was Castor. Then the constellation Punarvasu is quite equivalent to our Gemini, the Twins. In far antiquity (5800 B.C.) the spring equinoctial point was predicted by the heliacal rising of the Twins ...

The preceding age of Cancer could have been perceived as ruled by Virgo standing at high summer:

*41.4 + *80 = *121.4 and 121.4 / 365.25 * 26000 was 8642 years before the time of rongorongo. 8642 - 1842 AD = 6800 BC, when the northern vernal equinox had been in Cancer. 12500 BC (cfr the illustration above) - 6800 BC = 5700 years corresponds to 5700 / 26000 * 365.25 = 80 right ascension days, which means that in the age of Cancer (6800 BC) the thong which held it all together would have been around June 9 (80 + 80).

The 'Gate of Cancer' (the Sun rising at Praesepe, the Beehive, ε Cancri) could then naturally have referred to the Gate of Gemini:

... Men's spirits were thought to dwell in the Milky Way between incarnations. This conception has been handed down as an Orphic and Pythagorean tradition fitting into the frame of the migration of the soul. Macrobius, who has provided the broadest report on the matter, has it that souls ascend by way of Capricorn, and then, in order to be reborn, descend again through the 'Gate of Cancer'. Macrobius talks of signs; the constellations rising at the solstices in his time (and still in ours) were Gemini and Sagittarius: the 'Gate of Cancer' means Gemini. In fact, he states explicitly (I,12.5) that this 'Gate' is 'where the Zodiac and the Milky Way intersect' ...

9 months - the approximate duration of human pregnancy - after the Sun had reached Spica in Virgo the Gemini twins ought to have been born, viz. in day 3 / 4 * 365.25 = 160 (June 9) + 274 = 434 = 365 + 69 (March 10). *202 (Spica) + *274 - *365 = *111.4 (Propus, ι Gemini) = *41.4 (Bharani) + *70.0.

Propus ought to mean 'before the foot', because the first point in Gemini was out in the Milky Way River before the Sun reached the left foot of Castor (the mortal twin).

... 1. The Andean pan-pipe in my example has 13 'reeds', 7 above and 6 below:

In Andean thought the division into a high and a low part of the land is fundamental. This pair of inhabited bands of land are presumably illustrated by the pair of bands around the pipes; the rising Sun is first painting the top of the mountain range in red and gold.

The twin stars Castor and Pollux exhibit the same trait - one is born high and the other is low:

... In Greek and Roman mythology, Castor and Pollux or Polydeuces were twin brothers, together known as the Dioscuri. Their mother was Leda, but Castor was the mortal son of Tyndareus, king of Sparta, and Pollux the divine son of Zeus, who visited Leda in the guise of a swan. Though accounts of their birth are varied, they are sometimes said to have been born from an egg, along with their twin sisters Helen of Troy and Clytemnestra.

In Latin the twins are also known as the Gemini or Castores. When Castor was killed, Pollux asked Zeus to let him share his own immortality with his twin to keep them together, and they were transformed into the constellation Gemini. The pair was regarded as the patrons of sailors, to whom they appeared as St. Elmo's fire, and were also associated with horsemanship.

St. Elmo's fire (also St. Elmo's light) is a weather phenomenon in which luminous plasma is created by a coronal discharge from a sharp or pointed object in a strong electric field in the atmosphere (such as those generated by thunderstorms or created by a volcanic eruption). St. Elmo's fire is named after St. Erasmus of Formiae (also called St. Elmo, the Italian name for St. Erasmus), the patron saint of sailors. The phenomenon sometimes appeared on ships at sea during thunderstorms and was regarded by sailors with religious awe for its glowing ball of light, accounting for the name. Because it is a sign of electricity in the air and interferes with compass readings, sailors also regarded it as an omen of bad luck and stormy weather ...
