Alessandro Galilei - architect

After frustrations in England Florentine made mark in Rome

Giuseppe Berti's portrait of
Alessandro Galilei

The architect Alessandro Galilei, best known for the colossal Classical façade of the basilica of San Giovanni in Laterano in Rome, was born on this day in 1691 in Florence.

From the same patrician family as Renaissance polymath Galileo Galilei but not a direct descendant, Galilei’s father was a notary, Giuseppe Maria Galilei. Though his father considered the family to be noble still, their standing had fallen somewhat under Medici rule.

Alessandro studied mathematics and engineering at the prestigious Accademia dei Nobili in Florence, where he was instructed in building techniques and perspective among other things. 

As he sought to develop a career, Galilei met John Molesworth, son of Viscount Robert Molesworth, who spent three years in Florence as an envoy to the Medici court. Molesworth used his time there to indulge his interests in architecture, art, music, literature and poetry and developed a close friendship with Galilei, whose designs he admired.  He sponsored Galilei to spend time studying in Rome and when his posting in Italy was at an end, invited him to return to England with him.

Galilei’s designs had a Classical bent that put him at odds with the fashion for Baroque that was still dominant in Italy but appealed to Molesworth and to his father, who was keen to launch a new architectural movement, to which the subscribers included Sir Thomas Hewitt and Edward Lovett Pearce, who Galilei had met in Florence while Pearce was in Italy to study the architecture of Andrea Palladio.

The facade of Castletown House, home of Irish
politician William Conolly, was designed by Galilei

Although Galilei’s time in London yielded few commissions as Molesworth’s movement failed to take off, he had more success in Ireland, where Robert Molesworth introduced him to William Conolly, Speaker of the Irish House of Commons and the wealthy owner of Castletown House, a palatial house near Dublin. He invited Galilei to design a new façade, and though the Italian did not remain in England to execute his plans, they were carried through by Pearce.

Before he returned to Florence, Galilei also designed the Doric portico on the east front of Kimbolton Castle in Huntingdonshire for Charles, Duke of Manchester.

In 1719, Galilei was appointed engineer of court buildings and fortresses to the courts of the Grand Dukes of Tuscany, Cosimo III and Gian Gastone de' Medici. Again, however, his severe, heavily Classical designs failed to win him the grand projects he hoped to secure.

His fortunes changed in 1730 when a Florentine Cardinal, Lorenzo Cortini, was elected as pope, taking the name of Pope Clement XII. He called Galilei to Rome in 1731 to build his family's chapel, the Cappella Corsini, in the Basilica di San Giovanni in Laterano.

Pope Clement XII gave Galilei
his most prestigious project

At around the same time, Clement XII announced ambitious plans to renovate the basilica, which was the oldest and highest ranking of the four papal basilicas in the city but had suffered neglect after twice being damaged by fire in the 14th century, before being rebuilt in the 16th century.

He announced a competition for a new façade. Designs were submitted by 26 architects and the award of the commission to Galilei attracted raised eyebrows, especially since the consensus was that Luigi Vanvitelli’s entry was far superior.

Galilei completed the project in 1735, after which the sheer scale of his design, topped with enormous statues of saints, attracted more controversy, with critics complaining that it was far more suited to a palace than a church. It was not until Neoclassicism became popular in subsequent years that his work earned the appreciation that was missing in his lifetime.

Also responsible for the Baroque façade of the church of San Giovanni dei Fiorentini in Rome, Galilei died in Rome in 1737, at the age of just 46. A portrait of him by his contemporary, Giuseppe Berti, today hangs in the entrance hall of Castletown House.

Galilei's façade of the Basilica di San
Giovanni in Laterano was controversial

Travel tip:

Although the Basilica di San Giovanni in Laterano is in the Appio/San Giovanni neighbourhood of Rome, southeast of the city centre, some 4km (2.5 miles) southwest of the Vatican, because it is a property of the Holy See, the basilica and its adjoining buildings enjoy an extraterritorial status from Italy, in accordance with the terms of the Lateran Treaty of 1929. The oldest and most important of Rome’s four major basilicas, it is officially Rome’s cathedral.  The church’s history can be traced to the reign of the Roman emperor Constantine the Great, who converted the Lateran Palace to a church in 324 after he had converted to Christianity.  

The church of San Giovanni dei
Fiorentini overlooks the Tiber

Travel tip:

The church of San Giovanni dei Fiorentini can be found in the Ponte district of central Rome, overlooking the Tiber, just across the river from Castel Sant’ Angelo and about 10 minutes’ walk from Piazza Navona. It was conceived after Pope Leo X organised a competition in 1518 for a new church on the site of the old church of San Pantaleo. The architects who submitted designs included Baldassare Peruzzi, Jacopo Sansovino, Antonio da Sangallo the Younger and Raphael. Although Sansovino won the competition, the building was constructed by Sangallo and Giacomo della Porta, with Carlo Maderno taking over in 1602. Galilei’s façade was not added until 1734.

Jacopo Mazzoni – philosopher

Brilliant scholar could recite long passages from Dante

Jacopo Mazzoni was known for literary
criticism as well as philosophy

Jacopo Mazzoni, a University professor with a phenomenal memory who was a friend of Galileo Galilei, died on this day in 1598 in Ferrara in Emilia-Romagna.

Mazzoni, also sometimes referred to as Giacomo Mazzoni, was regarded as one of the most eminent scholars of his period. His excellent powers of recall made him adept at recalling passages from Dante, Lucretius, Virgil and other writers during his regular debates with prominent academics. He relished taking part in memory contests, which he usually won.

Mazzoni was born in Cesena in Emilia-Romagna in 1548 and was educated at Bologna in Hebrew, Greek, Latin, rhetoric and poetics. He later attended the University of Padua where he studied philosophy and jurisprudence.

He became an authority on ancient languages and philology and promoted the scientific study of the Italian language.

Galileo Galilei was a fellow
professor at Pisa University

Although Mazzoni wrote a major work on philosophy, he became well known for his works on literary criticism, in particular for his writing in defence of Dante’s Divine Comedy - Discorso in Difesa Della Commedia della Divina Poeta Dante - published in 1572 and Della Difesa Della Commedia di Dante, which was not published until 1688.

Mazzoni was also influenced by Plato and Aristotle and often made references to their works.

In turn, his theories about poetry influenced romantic writers who came later such as Samuel Taylor Coleridge and Friedrich von Schiller.

Mazzoni is also credited with helping to found the Accademia della Crusca, a society of scholars of Italian linguistics and philology, in 1583. The academy, in Florence, is the oldest linguistic academy in the world and the most important research institution into the Italian language.

The pala - shovel - given to Mazzoni
by the Accademia della Crusca

Crusca is the Italian word for bran, its use a reflection of the society's symbology, which likened 'good' language to flour sifted from bran.  The society's emblem was the frullone, a machine used to separate flour from bran. The operator would load bran into the machine using a pala - shovel - and the society extended the symbolism by presenting each member with a shovel bearing the member's name and a motto, usually a line of verse.

Mazzoni worked as a university professor, first at Macerata and then at Pisa, where he taught philosophy from 1588 to 1597. It was there he met Galileo, who was a young mathematics professor at the university. They became good friends and in May 1597, Galileo wrote Mazzoni a letter in which he commented on Mazzoni’s latest book, In universam Platonis et Aristotelis philosophiam praeludia, and also stated his inclination towards the Copernican system over the Ptolemaic one.

Later that year, Mazzoni accepted the chair in philosophy at Rome’s La Sapienza University.

He was asked to accompany Cardinal Pietro Aldobrandini on a mission to Venice in 1598. After they stopped off in Ferrara on the way back, Mazzoni was taken ill and later died. He was 57 years old.

The Rocca Malatestiana in Cesena, once a prison, now
houses a museum of agriculture

Travel tip:

Cesena, the birthplace of Jacopo Mazzoni, is a city in Emilia-Romagna, south of Ravenna and west of Rimini. One of the main sights in the town is the 15th century Biblioteca Malatestiana, which houses many valuable manuscripts and was the first public library in Europe. The library has been preserved in its 15th century condition and is now a listed UNESCO World Heritage site. The city’s castle, the Rocca Malatestiana, was used by Cesare Borgia as a prison during the Italian Wars and is now a museum.

The Castello Estense is the centrepiece of the city
of Ferrara, where Mazzoni died

Travel tip:

Ferrara, where Jacopo Mazzoni died, is a city in Emilia-Romagna, about 50 km (31 miles) to the northeast of Bologna. It was ruled by the Este family between 1240 and 1598. Building work on the magnificent moated Este Castle (Castello Estense) in the centre of the city began in 1385 and the castle was added to and improved by successive rulers of Ferrara until the end of the Este line. The castle was purchased for 70,000 lire by the province of Ferrara in 1874 to be used as the headquarters of the Prefecture. You can still see Ferrara’s original narrow, medieval streets to the west and south of the city centre, between the main thoroughfares of Via Ripa Grande and Via Garibaldi. These were the original heart of the city in the middle ages before the Este family redesigned it.

Francesco Barberini – Cardinal

Patron of the arts sympathised with Galileo

Francesco Barberini knew Galileo from his
days as a student at the University of Pisa

Francesco Barberini, a cardinal who as Grand Inquisitor of the Roman Inquisition refused to condemn the scientist Galileo Galilei as a heretic, was born on this day in 1597 in Florence.

As a cardinal working within the Vatican administration, Barberini also became an important patron of literature and the arts.

The son of Carlo Barberini and Costanza Magalotti, Francesco was assisted by Galileo during his studies at the University of Pisa. The scientist was also a family friend. Francesco graduated in canon and civil law at the age of 25 in 1623.

Later that year, his uncle, Maffeo Barberini, who had been recently elected as Pope Urban VIII, made him a cardinal and sent him to be papal legate to Avignon.

He was sent to Paris as a special legate to negotiate with Cardinal Richelieu and then to Spain as a papal legate, but both his missions were unsuccessful.

From 1628 onwards Barberini led the foreign diplomacy of the Papal States, always favouring France.

Galileo subscribed to the view that the Earth
was not the centre of the universe

From 1633 until his death more than 40 years later, Barberini was the Grand Inquisitor of the Roman Inquisition. He was part of the Inquisition tribunal investigating Galileo after the publication of writings supporting the arguments put forward by the German scientist Nicolaus Copernicus that the sun and not the earth was the centre of the universe.

He was one of three members of the tribunal who refused to condemn the scientist, although the majority verdict was that Galileo was "vehemently suspect of heresy" and he was sentenced him to indefinite imprisonment, later commuted to house arrest, where he remained until his death in 1642.

The Barberini family fortunes declined after hostilities between the papacy and the Duchy of Parma and Piacenza led to the First War of Castro in which the papacy did badly. Peace was concluded only a few months before the death of Urban VIII.

Once it became clear that the Barberini candidate for the papacy was not going to be elected. Francesco and his brother, Antonio, switched their support to Giovanni Battista Pamphili.

But after Pamphili became Pope Innocent X, he launched an investigation into their handling of the finances during the War of Castro, forcing the Barberini brothers to flee to Paris.

Two years later, Francesco Barberini was pardoned, his properties were restored to him and he was able to continue as a patron of the arts.

He was a member of various literary associations and secured altarpiece commissions for St Peter’s from prominent artists, such as Pietro da Cortona and the French Baroque painter, Poussin.

Barberini bought several paintings by Poussin for himself during the artist’s early years living in Rome.

In 1625 he had acquired the former Sforza palace and, after buying further land, he engaged the architect, Carlo Maderno, to transform it into a much larger and grander building, which eventually became Palazzo Barberini.

Francesco Barberini died in Rome in 1679 at the age of 82.

The Palazzo alla Giornata on the Arno embankment is
one of the main buildings of the University of Pisa

Travel tip:

The University of Pisa, where Galileo taught and Francesco Barberini studied, was founded in 1343 making it the 10th oldest in Italy and it houses Europe’s oldest academic botanical garden. The main University buildings are in and around Lungarno Antonio Pacinotti, overlooking the River Arno, a short walk from the city’s famous Leaning Tower.

The Palazzo Barberini was Barberini's home in the
centre of Rome, just off Piazza Barberini

Travel tip:

Palazzo Barberini is just off Piazza Barberini in the centre of Rome. It was completed in 1633 as a home for Francesco Barberini and was the work of three great architects, Carlo Maderno, Francesco Borromini and Gian Lorenzo Bernini. The palace now houses part of the collection of Italy’s National Gallery of Ancient Art.

Galileo demonstrates potential of telescope

Scientist unveiled new instrument to Doge of Venice

How the Milanese artist Giuseppe Bertini imagined the
scene as Galileo demonstrated his telescope to the Doge

The scientist and inventor Galileo Galilei demonstrated the wonders of the telescope to an audience of Venetian lawmakers on this day in 1609.

The 90th Doge, Leonardo Donato, and other members of the Venetian senate accompanied Galileo to the top of the campanile of St Mark’s Basilica, where each took it in turn to look through the instrument.

The meeting had been arranged by Galileo’s friend, Paolo Sarpi, who was a scientist, lawyer and statesman employed by the Venetian government. The two were both professors at the University of Padua.

Galileo, whose knowledge of the universe led him to be called the ‘father of observational astronomy’, was for many years wrongly credited with the invention of the telescope when in fact the first to apply for a patent for the device was a Dutch eyeglass maker named Hans Lippershey.

However, Galileo’s work using uncertain details of Lippershey’s design certainly took the idea to a different level.

Like Galileo, Paolo Sarpi was a professor
at the University of Padua

Whereas Lippershey’s device magnified objects by about three times, Galileo eventually produced a telescope with a magnification factor of 30.

The one he demonstrated on August 25, 1609, is thought to have had a factor of about eight or nine.

Galileo was the first to realise the potential of the telescope for astronomical study.

He was able to make out mountains and craters on the moon, as well as a ribbon of diffuse light arching across the sky — the Milky Way.  Galileo also discovered the rings of Saturn, sunspots and four of Jupiter's moons.

It was his findings on Jupiter’s moons in January 1610 that would lead him indirectly into trouble with the Roman Inquisition over his belief in heliocentrism, the concept that the sun and not the Earth was the centre of the solar system, as had been theorised by the Polish scientist Nicolaus Copernicus in the previous century.

In observing the three objects in proximity to the planet Jupiter that he had originally thought to be distant stars, he noticed that their position relative to the planet changed in a way that would have been inexplicable if they had really been fixed stars.

One day he noticed that one of them had disappeared altogether only to reappear later and within a few days had concluded that they were orbiting Jupiter. When, later in the year, he discovered that the planet Venus had ‘phases’ similar to the earth’s Moon, when differences in appearance suggested different positions in the sky, he began to subscribe firmly to the Copernican theory.

This flew in the face of a major part of Roman Catholic belief, based on the Aristotelian principle that all heavenly bodies orbited the Earth.

In time, Galileo was found guilty of heresy and forced to recant his views under threat of torture. He would have spend the last years of his life in prison had the court not shown some clemency and commuted his sentence to house arrest.

The campanile of St Mark's is a famous landmark
in Venice, towering over the basilica

Travel tip:

The Campanile of St Mark’s has become one of the symbols of Venice, instantly recognisable as part of the landscape of St Mark’s Square - Piazza San Marco - standing away from the basilica itself. Constructed in the ninth century, one of its first uses was a watchtower or lighthouse. Over the centuries it has been restored and added to several times, often following regular lightning strikes.  It assumed its definitive shape in the 16th century with restorations made to repair damage caused by the earthquake of March 1511, when the belfry, attic and spire were added. The whole structure collapsed in 1902, a few days after a large crack appeared in the north wall, it is thought because of erosion of the foundations after almost 1,000 years, but was rebuilt over the following 10 years.

Travel tip:

Galileo lived under house arrest was Villa Gioella, a house he rented a couple of miles from the from the centre of Florence in the Arcetri hills.  In Galileo’s time it was a farmhouse, surrounded by many acres of land. The area is also home to the Arcetri Observatory, which was opened in 1872 after astronomers at La Specola Observatory, not far from the Pitti Palace, decided that pollution from artificial light was making clear images impossible.
