The Heavenly Twins were shown to be the patrons of many human arts and industries, especially they were credited with the invention of the Plough and the invention of the Ship. It was shown that in each case the Woodpecker parent was really responsible. From this point a new departure was made with the greatest of all the Greek Myths, the story of the Argonauts. Jason was shown to be a Heavenly Twin and his ship to be manned, for the most part, by pairs of twin heroes. The ship had been evolved out of a dug-out with twins on board, just such an alveus as Romulus and Remus were exposed in on the Tiber!
