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." (Wikipedia)

"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." (Wikipedia)
