The first mention of this curve is the Florentine monk Guido Grandi in two letters to Leibniz in December 1713 and calls it "rhodonea", from the Greek. ῥόδον - "rose"). Ten years later he published an article about her in The Philosophical Works of the Royal Society, where he examined varieties of this curve with a different number of petals and also called them " rose-shaped". Five years later, Guido Grandi developed the theory of rose-shaped curves in a separate work.
