Rota Fortunae
The concept developed in antiquity; it was used by Cicero. The Wheel originally belonged to the Roman goddess Fortuna, whose name seems to derive from Vortumna, "she who revolves the year". Fortuna eventually became Christianized: the Roman philosopher Boethius (d. 524) was a major source for the medieval view of the Wheel, writing about it in hisConsolatio Philosophiae.
