The Wheel of Fortune motif appears significantly in the "Carmina Burana" (or "Burana Codex"), over one thousand poems and songs — often profane in content — written by students and clergy in the early 13th century. Excerpts from two of the collection's better known poems, ""Fortuna Imperatrix Mundi" (Fortune, Empress of the World)" and ""Fortune Plango Vulnera" (I Bemoan the Wounds of Fortune)," read: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 his"Consolatio Philosophiae".vv
