Life Best Works Photo Gallery Home Page Maria Teresa Agnesi Life Italian composer, harpsichordist, singer and librettist: as a girl she performed in her home while her elder sister Maria Gaetna (1718-99; she became a distinquished mathematician) lectured and debated in Latin. Charles de Brosses, who heard them on 16 July 1739 and was highly impressed, reported that Maria Teresa performed harpsichord pieces by Rameau and both sang and played compositions of her own invention. Her first theatrical work, Il restauro d'Arcadia, was successfully presented in Milan's ducal theatre in 1747. At about this time she dedicated collections of her own arias and instrumental pieces to the rulers of Saxony and Austria; according to Simonetti the Empress Maria Theresa sang from a collection of arias that Agnesi had given her. MIDI FILE - Sonata for keyboard (4'13'') She married Pier Antonio Pinottini on 13 June 1752 but had no children. Her next opera, Ciro in Armenia, produced a the Regio Ducal Teatro in 1753, was to her own libretto. In 1766 her Insubria consolata was performed in Milan to honour the engagement of Beatrice d'Este and the Archduke Ferdinand.

The Witch of Agnesi
by
Daphne Golden and Melissa Hanzsek-Brill
Historical Background Maria Gaetana Agnesi (1719-1799) of Milan was a gifted scholar and linguist who was first published at the age of nine with a Latin essay defending higher education for women. She was a well-published scientist by the age of 20 and was made an honorary member of the faculty at the University of Bologna with the consent of the pope at the age of thirty. She later retired to devote herself to her religious work. Her two volume textbook was the first comprehensive textbook on the calculus after L'Hopital's earlier book. She is most famous for her curve Agnesi called versiera, or turning curve. We know this curve by the name the "witch of Agnesi" because a British mathematician, John Colson, translated the word versiera incorrectly. See an animation with GSP? Investigations of the Witch Curve The algebraic equation that generates this curve is By substituting the values 1,2, and 3 in for a, we get the following graphs using Algebra Xpresser GRAPH ONE:

About this list: This is by no means the ultimate database of women composers. In fact, this list represents only a tiny fraction of more than 6000 women composers about whom a record exists (e.g. Aaron Cohen's Encyclopedia of Women Composers lists 6,196 women composers). Only composers of classical music whose works have been recorded on compact disc have been included in this database. Composers are listed in alphabetical order; their name is followed by their date of birth and country of origin. Where a link to online resources exists it has also been provided.

Curiosidade VI - A feiticeira de Maria Agnesi Plotando os pontos P(x, y) da curva de equação x .y + a
num sistema de coordenadas cartesianas xOy , obteremos o gráfico a seguir:
Desenvolvendo a equação acima, vem:
x .y + a
Colocando y em evidencia, fica: y(x + a ) = a
Podemos escrever, finalmente: A curva representativa dessa equação, pode ser obtida conforme figura abaixo, onde os pontos P(x, y), são obtidos pela interseção dos segmentos BP (horizontal) e AP (vertical) , perpendiculares entre si, onde A é obtido pela interseção da semi-reta OA com a tangente à curva no ponto C
(reta y = a) e B é obtido pela interseção da mesma semi-reta com a circunferência de diâmetro OC = a. Fazendo-se a semi-reta OA variar, mantendo-se o ponto O fixo e variando-se o ângulo t, iremos obtendo novos pontos A , A , ... , que, pelo critério acima, irão determinando os novos pontos da curva. Esta curva,é conhecida pelo sugestivo nome de Bruxa de Agnesi ou Feiticeira de Maria Agnesi Segundo o que já li sobre o assunto, Maria de Agnesi não tinha nada que pudesse associa-la a uma bruxa. Ao contrário, tratava-se de uma pessoa sensível,muito inteligente e, bastante preocupada com os mais carentes. Consta que o nome bruxa ou feiticeira atribuído à curva , deveu-se a problemas relacionados com a tradução de um livro de sua autoria, que incluía uma discussão sobre a curva y = a / (x + a Podemos dizer que a denominação Curva de Agnesi faz muito mais justiça a Maria G. Agnesi, do que a denominação

90. Witch Of Agnesi
C Truesdell, Correction and Additions for maria Gaetana agnesi, Archive for Historyof Exact Science 43 (1991), 385386. This philosopher was maria agnesi.
http://hausdorff.math.yorku.ca/Courses/2041-42/CubicCurves/Agnesi.shtml
Why is it Called the "Witch of Agnesi"?
In the History of Analytic Geometry by Carl Boyer In footnote 41 on page 179 one learns that:
The name "witch," customarily used in English, apparently is due to a mistranslation. The word "versiera" which Grandi coined in 1718 to indicate the manner in which the curve is generated, has also the meaning "witch" in Italian, but this has no connection with what Grandi and Agnesi had in mind. Further to this, Alfred Ross says that:
...Luigi Guido Grandi (1671-1742) studied this curve in 1703. He named it the versaria, meaning "turning in every direction." In 1748, Maria Gaetana Agnesi (1718-1799), in Istituzioni Analitiche, the first calculus book written by a woman, called the curve the versiera. The British mathematician John Colson (1680-1760), translating Agnesi's work into English, translated the Italian word versiera (intended to mean "turning curve") as "the witch curve." (The Italian word avversiera can be translated "wife of the devil.") Some sources indicate Colson mistranslated the word; other sources indicate Agnesi had confused an old Italian word meaning "free to move" with another meaning "witch." and contributes the following web site as a reference David Fowler provides a slightly different view on the matter:
The treatise Instituzioni analitiche ad uso della gioventu italiana contains no original mathematics by Agnesi. Rather the book contains many examples which were carefully selected to illustrate the ideas; one review calls it an: ... exposition by examples rather than by theory.

THE WITCH OF AGNESI
by John H. Lienhard
Click here for audio of Episode 217. Today, we meet the Witch of Agnesi. The University of Houston's College of Engineering presents this series about the machines that make our civilization run, and the people whose ingenuity created them. H ere's an old geometry book. One of its problems leads you to construct a singularly gentle and graceful curve. We're told that the curve is called the Witch of Agnesi. But why? There's nothing sinister about its flowing line. It turns out that one person who worked with this curve was Maria Agnesi, a noted 18th-century Italian mathematician a woman mathematician! So she was the Witch. Well, perhaps. But maybe we should meet the lady. Maria Agnesi was born in 1718, the daughter of an Italian mathematics professor at the University of Bologna. She was a child prodigy and the apple of her father's eye. Yet she was shy and retiring. She wanted to become a nun, but her father wouldn't have that. Still, she never married. When she was twenty, her mother died and she took responsibility for the household. She also began work on what was already her second book. That book was a two-volume treatise on the new differential and integral calculus. It took ten years for her to complete, and it was a major step in bringing the calculus to general use. It was in this extremely important work that she showed how the calculus could be used to create the curve that would later be called the Witch of Agnesi. The work was recognized in its time. Her queen rewarded it with a gift, and the Pope arranged her appointment to the faculty of the University of Bologna.
