Maria Gaetana Agnesi – mathematician

Brilliant scholar gave her time and money to the poor

Maria Gaetana Agnesi learned
seven languages by the age of 11

Maria Gaetana Agnesi, the first woman to write a mathematics handbook, was born on this day in 1718 in Milan.

Maria became a mathematician, philosopher, theologian and humanitarian and was also the first woman to be appointed as a mathematics professor at a university.

She was one of at least 21 children born to Pietro Agnesi, a wealthy man whose family had made their money from silk production. Her mother was his first wife, Anna Fortunato Brivio, who was from a noble Milanese family.

Maria was soon recognised as a child prodigy, who could speak Italian and French by the time she was five and had learnt Greek, Hebrew, Spanish, German and Latin by the time she was 11.

When she became ill at the age of 12, it was thought to have been because of excessive studying and reading, but after she was prescribed vigorous dancing and horse riding to improve her health, she suffered convulsions and was then advised to moderate her activities.

By the time Maria was 14 she was studying ballistics and geometry. Her father regularly invited learned men to his house to listen to her read and to discuss philosophical questions with her.

After Maria’s mother died, her father remarried twice and Maria was given the task of teaching all her siblings and half-siblings.

This stopped her from fulfilling her wish to enter a convent.  Instead, her father agreed to let her live away from society and devote herself to the study of mathematics.

In 1740 she began studying differential and integral calculus with esteemed Italian mathematician Ramiro Rampinelli.

By 1748 Maria had published her Instituzioni analitiche ad uso della gioventù italiana. She said this was to give a systematic illustration of the different results and theorems of infinitesimal calculus. The work was translated into French and English and Maria received letters and gifts from the Habsburg Empress Maria Theresa and Pope Benedict XIV.

In the book, Maria discusses a curve that had been studied earlier by the mathematician Luigi Guido Grandi. He had called the curve ‘versoria,’ the Latin word for a rope that turns a sail, because that is what it reminded him of.  This was mistranslated as the word ‘witch’ in the English version and so the curve became known as ‘The Witch of Agnesi’.

In 1750 Pope Benedict XIV appointed Maria to the chair of mathematics and natural philosophy and physics at Bologna University, although she never actually taught there. She was the second woman in the world to be granted a professorship at a university, Laura Bassi, an Italian physicist being the first.

After the death of her father in 1752, Maria finally had the chance to study theology. She then worked with the poor, sick and homeless, founding a home for the elderly in Milan, where she went to live.

In January 1799, Maria Gaetana Agnesi died at the age of 80. She was buried in a mass grave for the poor along with 15 other bodies.

An asteroid, 16765 Agnesi, a crater on Venus and a brandy are all named after her, as well as the mathematical curve, the Witch of Agnesi.

The Villa Agnesi Albertoni at Montevecchia in the province
of Lecco, where Maria and her family spent the summer

Travel tip:

You can visit the Villa Agnesi Albertoni, where Maria and her family spent time during the summer, which is in Largo Maria Gaetana Agnesi at Montevecchia in the province of Lecco, about 30 kilometres (19 miles) northeast of Milan. The villa has been preserved in the rococo style in which it was built during the 17th century. Visitors can still see the ‘salotto’, where eminent visitors would discuss philosophy with Maria Gaetana Agnesi and hear one of her sisters, Maria Teresa Agnesi play her own compositions on the harpsichord.

The famous Archiginnasio, the
university's anatomical theatre

Travel tip:

Bologna University, where Maria Gaetana Agnesi was the first woman to be appointed as a mathematics professor, was founded in 1088, making it the oldest university in the world. It attracted popes and kings as well as students of the calibre of Dante, Copernicus and Boccaccio. You can still visit one of the original university buildings in the centre of Bologna, the former anatomy theatre, the Archiginnasio, in Piazza Galvani. It is open Monday to Saturday from 9 am to 1 pm, admission free.

Bomb destroys Archiginnasio anatomical theatre

Historic facility hit in 1944 air raid

The Archiginnasio anatomical theatre is surrounded by
statues of eminent physicians carved in wood

The historic anatomical theatre of the Palazzo Archiginnasio, the original seat of the University of Bologna, was almost completely destroyed in a bombing raid on the city by Allied forces on this day in 1944.

The northern Italian city was a frequent target during the final two years of the conflict because of its importance as a transport hub and communications centre.  The wing of the palazzo housing the anatomical theatre, built between 1636 and 1638, took a direct hit on the night of January 29.

Although it is unlikely that the university - the oldest in the world - was a specific target, bombing was much less precise 75 years ago and collateral damage was common and often widespread.

As well as its importance in the history of medical research, the anatomical theatre was notable as an art treasure, mainly for the 18th century carved wooden statues by Silvestro Gianotti depicting great physicians of history, from the Greek physicians Hippocrates and Galenus onwards, including many who worked at the university, such as Fabrizio Bartoletti, Marcello Malpighi, Mondino de Liuzzi and Gaspare Tagliacozzi.

Gaspare Tagliacozzi was one of the many
physicians who worked in the Archiginnasio

The theatre, built in the form if an amphitheatre, was designed in 1637 by the Bolognese architect Antonio Levanti, a pupil of Annibale Carracci.

The ceiling, completed between 1647 and 1649 had the figure of Apollo, the god of Medicine, in the middle, surrounded by symbolic images of constellations carved in wood.

The centrepiece of the table was the white table on which the dissection of human or animal bodies took place.  These were open to the public and took place in the presence of an Inquisition priest.

To the side, in an elevated position, the cattedra del lettore - teacher’s desk - was flanked by two spellati - skinned men - statues, sculpted in 1734 from drawings by Ercole Lelli, a local painter of the late Baroque period who became famous for his anatomical sculptures in wax.

Incredibly, despite the destruction, the theatre was faithfully reconstructed after the war had ended thanks to the painstaking recovery from the rubble of anything that could be reused, including the majority of the statues.

The theatre today is open daily to the public, along with other parts of the Palazzo Archiginnasio, which was the seat of the university until 1803. The original marble table is not the one on display, mainly out of consideration for visitors whose sensitivities might be offended by the sight of indelible blood stains.

The city of Bologna as a whole suffered extensive damage from bombing during the Second World War II. The worst raids took place in 1943. On July 24, a massive bombardment destroyed a significant part of the historic city centre and killed about 200 people, with 44 per cent of the buildings in the centre listed as having been destroyed or severely damaged. On September 25, sustained bombing of the wider city left more than 1,000 people dead.

which was completed in 1563

Travel tip:

The construction of the Archiginnasio, situated behind the Basilica di San Petronio, began after nearby Piazza Maggiore was remodeled under papal orders in the 16th century. It was commissioned by Pope Pius IV through the papal legate Charles Borromeo, who entrusted the project to the architect Antonio Morandi. The building, inaugurated on October 21, 1563, was to house the Schools of the Legisti (Canon and Civil law) and Artisti (philosophy, medicine, mathematics, natural sciences and physics). The building was named Archiginnasio after the classical term which was used to designate the Studium, as the University was first called, of Bologna. The Archiginnasio ceased to be the seat of the university in 1803, when the university moved to Palazzo Poggi, where it is still located today.  The original building now houses the Archiginnasio Municipal Library, the largest library in Emilia-Romagna.

The Basilica di San Petronio is the largest brick-built church
in the world, reaching 51m (167ft) high

Travel tip:

The Basilica di San Petronio, is the main church of Bologna, located in Piazza Maggiore in the centre of the city. It is the largest, brick-built church in the world. Building work began on the church in 1390 and it was dedicated to San Petronio, who had been the Bishop of Bologna in the fifth century. The 10th-largest church in the world at 132m (433ft) long and 66m (271ft), the vault reaches 45m (148ft) inside and 51m (167ft) in the facade. The basilica, built as a communal project, was finally consecrated in 1954. It has been the seat of the relics of Bologna's patron saint only since 2000.  Work on the facade was abandoned in the early 16th century by order of Pope Pius IV over fears that it would upstage St Peter's Basilica in Rome as the grandest church in Italy. It has never been completed.
