	Eratosthenes does not recount any myth about the river boat on which the archer stands, nor does Geminos give any reasons for the definition of the constellation. It is unclear where the inspiration came from to describe the group as a wreath. However, the Egyptianised style of the Dendera zodiac shows the centaur-like archer on small boats beneath his hooves. This is not surprising in Egypt, where for thousands of years the stars were imagined to glide silently across the sky on barges.

	It is quite possible, although not certain, that Eratosthenes' text proves a cultural transfer: In the 3rd century BC, the Syrian wars raged between the Ptolemies, who ruled Egypt, and the Seleucids, who ruled Mesopotamia. In the last years of Eratosthenes' life and work, there had been a period of peace that made the 2nd century BC, until the Parthian Wars, an extraordinary heyday of scientific exchange between Babylon and Alexandria. Eratosthenes thus brings together Mesopotamian and newly developed Greek culture.

	Modern literature sometimes claims that Hyginus made a possible star prophecy: he tells of a myrtle wreath in memory of the deceased mother of the god Dionysus. However, it is unclear whether he is referring to Corona Borealis or Australis. If Hyginus, the librarian of Augustus, invented the constellation ‘Southern Crown’, there could be a connection to the emperor and his laurel wreath.

	It is astonishing that the Southern Crown is depicted on the Farnese Globe. The globe is dated to the 2nd century AD, i.e. the time of Ptolemy. Since the figures are depicted in the Greek style, the globe is considered to be a copy of a Greek original from the BC era. However, since this star group was not referred to as a wreath until the 1st century AD, the sculptor must have reworked this star figure in a contemporary style. It looks less like a Caesar's crown than a bridal wreath.		It is astonishing that the Southern Crown is depicted on the Farnese Globe.
