'''Dom Guido Grandi''', O.S.B. Cam., (October 1, 1671 – July 4, 1742) was an Italian [[monk]], [[priest]], [[philosopher]], [[mathematician]], and [[engineer]].

== Mathematical studies ==

In 1701 Grandi published a study of the [[conical loxodrome]], followed by a study in 1703 of the curve which he named ''versiera'', from the Latin: ''vertere'' (to turn).

This curve was later studied by [[Maria Gaetana Agnesi]], one of the few women scientists to achieve a degree.

Through a mistranslation by the translator of her work into English who mistook the term "witch" (Italian: ''avversiera'') for Grandi's term, this curve became known in English as the [[witch of Agnesi]].

It was through his studies on this curve that Grandi helped introduce [[Leibniz]]' ideas on [[calculus]] to Italy.

In [[mathematics]] Grandi is best known for his work ''[[Flores geometrici]]'' (1728), studying the [[rose curve]], a curve which has the shape of a petalled flower, and for [[Grandi's series]].

He named the rose curve ''rhodonea''.

He also contributed to the Note on the Treatise of Galileo Concerning Natural Motion in the first Florentine edition of [[Galileo Galilei]]'s works.
