Gaspare Nadi - builder and diarist

Craftsmen kept chronicle for 50 years

The bell tower of the Palazzo d'Accursio in
Bologna was one of Nadi's projects

Gaspare Nadi, a builder who became famous for the insight into life in 15th century Italy provided by a diary he maintained for half a century, was born on this day in 1418 in Bologna.

Nadi worked on several important buildings in Bologna, including the bell tower of the Palazzo d’Accursio and several churches. He built the library of the Basilica of San Domenico.

He attained the position of Master Mason in the local guild of bricklayers, whom he also served for many terms as guild manager and other official positions.

Yet it was the diary he began to compile in 1452 that became his legacy. Written in idiomatic Bolognese, it proved to be an extraordinary document, a source for historians seeking to understand how families and society functioned in the Italy of Nadi’s lifetime.

As well as detailing family issues, the diary explained much about the construction industry of the time, with entries about clients and remuneration, injuries suffered by workers, the times demanded to turn around projects and the workings of the guilds, even down to the taverns in which members met and the vineyards that supplied their wine.

Nadi's extraordinary diaries are still
available to read today

There were also references to broader topics such as the duties of the city corporations in relation to the maintenance of public order and the pursuing of thieves. Nadi described deliberations on how a defence force would be enlisted for circumstances in which the city was in danger from its enemies.

Nadi was born in a house on the Via dei Pelacani (now Via Giuseppe Petroni) in the parish of San Vitale in Bologna. His father, Filippo di Domenico, a tanner, died in 1427, after which his mother, Chiara, married Giacomo Senzabarba, a shoemaker.

He moved to Faenza at the age of 15, with the intention of pursuing a career in the law. Two years later he returned to Bologna but his step-father refused to maintain him there and he was forced to move out. Fortunately, he was given by friends help first to learn to read and write and then to find work.

He was apprenticed as a barber in 1436. However, the cost of training was prohibitive and he turned instead to learning how to build walls under the guidance of the master builder Bartolomeo Negri.  In May of that year, he helped the engineer Aristotele Fioravanti complete the bell tower of the Palazzo d’Accursio - also known as the Palazzo del Comune - in the centre of Bologna.

In 1444, after completing his professional training in Ferrara, he married Catelina di Antonio di Bernardo, the daughter of a Florentine tailor, and the following year he moved to live with his in-laws in Prato, where he continued to practice his profession.

Catelina bore him six children and six other failed pregnancies in the space of 13 years, which is thought to have contributed to her death in 1462, after which Nadi married twice more, losing his second wife, Francesca, and his eldest son, Girolamo, in an outbreak of plague.  His third marriage, to Caterina, was unhappy and Nadi moved out to live with another son, Giovanni.

He died in 1504 at the age of 85 and is buried in the parish church of San Vitale.

the Palazzo d'Accursio - or Palazzo del Comune

Travel tip:

The Palazzo del Comune in Bologna’s Piazza Maggiore began life in the 13th century as Palazzo d'Accursio, the residence of the jurist Accursius. Over time, it was expanded and attached to adjacent buildings to house civic offices. In 1336 it became the seat of the Anziani - Elders - the highest magistrates of the city, and then the city's seat of government. In the 15th century it was refurbished under the designs of the architect Fioravante Fioravanti, who added the clock tower - Torre d'Accursio - in which Nadi installed the bell.

The Due Torri - the Asinelli and Garisenda
towers - a feature of the Bologna skyline

Travel tip:

Via Giuseppe Petroni, where Nadi was born (known then as Via dei Pelacani) is in central Bologna, linking Piazza Giuseppe Verdi - home of the Teatro Comunale di Bologna, the city’s principal opera venue - with Piazza Aldrovandi, named after the geologist Ulisse Aldrovandi (1522- 1605). Piazza Aldrovandi has a permanent food market, with stands selling fruit and vegetable as well as cheese, fish and other produce on a daily basis. The Piazza Aldrovandi is only 550m along Strada Maggiore from the Due Torri - the Torre degli Asinelli, which is the tallest leaning medieval tower in the world, and its sister, the Garisenda tower - which represent one of the symbols of the city.

Giulio Romano – artist and architect

Painter from Rome left his mark on Mantua

Titian's portrait of Giulio Romano, painted
between 1536 and 1540

Giulio Romano, who was the principal heir to the artist Raphael and one of the most important initiators of the Mannerist style of painting, died on this day in 1546 in Mantua.

He is most remembered for his masterpiece, the Palazzo del Te, built on the outskirts of Mantua as a pleasure palace for the Gonzaga family, which was designed, constructed and decorated entirely by him and his pupils.

The artist had been born in Rome some time in the 1490s and was given the name, Giulio di Pietro di Filippo de’ Gianuzzi. He was known originally as Giulio Pippi, but later was referred to as Giulio Romano because of where he was born.

Giulio was apprenticed to Raphael when still a child and worked on the frescos in the Vatican loggias to designs by Raphael. He also collaborated with him on the decoration of the ceiling in the Villa Farnesina.

He became so important in the workshop that on Raphael’s death in 1520 he was named as one of the master’s chief heirs and he also became his principal artistic executor, completing a number of Raphael’s works, including the Transfiguration.

Romano's 1523 painting The Stoning of St Stephen

His own works from this time, such as the Madonna and Saints and the Stoning of St Stephen, both completed in 1523, show he had developed a highly personal, anticlassical style of painting.

The following year, at the invitation of the Gonzaga family, Giulio left Rome for Mantua, where he remained until his death, completely dominating the artistic affairs of the duchy.

In Mantua he worked on the rebuilding of the ducal palace and his decorations in the Sala de Troia are thought to foreshadow the Baroque style.

He also sculpted the figure of Christ that is positioned above Castiglione’s tomb in the Church of Santa Maria delle Grazie just outside Mantua.

Romano's Palazzo del Tel is 

Giulio’s studio became a popular school of art in Mantua and many of his pupils later achieved fame as artists themselves.

Drawings by Giulio that are still in existence are treasured by collectors and contemporary prints of them, engraved by Marcantonio Raimondi, made a significant contribution to the spread of Italian style throughout Europe.

The architect built a house for himself in Mantua, which was a Mannerist version of Raphael’s house in Rome. He started rebuilding the city’s cathedral the year before his death, in 1546.

Giulio Romano was buried in the Church of San Barnaba in Piazza Giuseppe Bazzani in Mantua.

The Palazzo Ducale in Mantua was the seat
of the ruling Gonzaga family

Travel tip:

Mantua is an atmospheric, old city in Lombardy, to the southeast of Milan, famous for its Renaissance Palazzo Ducale, the seat of the Gonzaga family between 1328 and 1707. Giulio Romano was well paid by the Gonzaga family and could afford to build his own residence in Via Carlo Poma. He reconstructed it from existing buildings, creating an elegant stone façade with arched windows on the upper floor. It still stands as an example of his genius and has some of his original frescos inside. 

The Palazzo del Te was designed as a pleasure palace
considered to be Giulio Romano's masterpiece

Travel tip:

Palazzo del Te, designed for Federico Gonzaga as a summer residence, is a fine example of the Mannerist school of architecture and is considered to be Giulio Romano’s masterpiece. The name for the palace came about because the location chosen had been the site of the Gonzaga family stables at Isola del Te on the edge of the marshes just outside Mantua’s city walls. After the building was completed in about 1535, a team of plasterers, carvers and painters worked on the interior for ten years until all the rooms were decorated with beautiful frescoes.

Galileo Ferraris - electrical engineer

Pioneer of alternating current (AC) systems

The engineer Galileo Ferraris saw himself
as a scientist rather than an entrepreneur

The physicist and electrical engineer Galileo Ferraris, who was one of the pioneers of the alternating current (AC) system for transmitting electricity and invented the first alternators and induction motors, was born on this day in 1847 in Piedmont.

The AC system was a vital element in the development of electricity as a readily-available source of power in that it made it possible to transport electricity economically and efficiently over long distances.

Ferraris did not benefit financially from his invention, which is still the basis of induction motors in use today. Another scientist, the Serbian-born Nikola Tesla, patented the device after moving to the United States to work for the Edison Corporation.

Tesla had been working simultaneously on creating an induction motor but there is evidence that Ferraris probably developed his first and as such is regarded by many as the unsung hero in his field.

He saw himself as a scientist rather than an entrepreneur and, although there is no suggestion that his ideas were stolen, openly invited visitors to come in and see his lab.  Unlike Tesla, he never intended to start a company to manufacture the motor and even had doubts whether it would work.

One of Ferraris's early motors, currently
in a museum in Sardinia

Born in Livorno Vercellese, a small town in the Vercelli province of Piedmont now known as Livorno Ferraris, Galileo Ferraris was the son of a pharmacist and the nephew of a physician in Turin, to whom he was sent at the age of 10 to obtain an education in the classics and the sciences.

Ferraris was was a graduate of the University of Turin and the Scuola d’Applicazione of Turin, emerging with a master's degree in engineering. He remained in the academic world and independently researched the rotary magnetic field.

He experimented with different types of motors and his research and his studies resulted in the development of an alternator, which converted mechanical (rotating) power into electric power as alternating current.

While Tesla sought to patent his device, Ferraris published his research in a paper to the Royal Academy of Sciences in Turin and the alternator as a source of polyphase power became key in the history of electrification, along with the power transformer.

These inventions enabled power to be transmitted by wires economically over considerable distances and electricity to be generated by harnessing the natural power of water, thus enabling power to be available in remote places.

The city of Turin marked the contributions made to science by Ferraris, who also researched in the field of optical instruments, with the creation of a permanent monument at the Royal Italian Industrial Museum of Turin (now the Royal Turin Polytechnic).  From 1934 to 2006, the "Galileo Ferraris" Electrotechnical Institute could be found in Corso Massimo d'Azeglio.

The Palazzo Chiablese di Castell'Apertole, the former
Savoy hunting lodge near Livorno Ferraris

Travel tip:

Known at different times as Livorno Piemonte as well as Livorno Vercellese, Livorno Ferraris occupies a wide area of countryside in the province of Vercelli in the plain of the Po river, bisected by the Depretis, Cavour and Ivrea canals. Located about 40km (25 miles) northeast of Turin and about 25km (16 miles) west of the city of Vercelli, it  hosted the conclave for the election of the antipope Benedict XIII in 1384. Nearby is the 18th century Palazzo Chiablese di Castell'Apertole, a former hunting lodge of the Savoy royal family.

The modern Politecnico di Torino of today

Travel tip:

The Royal Turin Polytechnic can be found in Corso Duca degli Abruzzi in the centre of Turin, about 2.5km (1.5 miles) from the Royal Palace. It evolved from the Royal Italian Industrial Museum, which was established in 1862 by Royal Decree as an Italian equivalent of the South Kensington Museum of London and of the Conservatoire des Arts et Métiers of Paris, to promote industrial education and the progress of industry and trade. Parallel with Corso Duca degli Abruzzi is the Corso Galileo Ferraris, a long, straight road that links the Giardino Andrea Guglielminetti with the Stadio Olimpico Grande Torino, the home of Torino football club, a distance of 4.1km (2.5 miles).

Poggio Bracciolini – scholar and humanist

Calligrapher who could read Latin changed the course of history

The linguist and scholar Poggio Bracciolini was
born in a village near Arezzo in Tuscany

Gian Francesco Poggio Bracciolini, who rediscovered many forgotten Latin manuscripts including the only surviving work by the Roman poet and philosopher, Lucretius, died on this day in 1459 in Florence.

For his services to literature he was commemorated after his death with a statue by Donatello and a portrait by Antonio del Pollaiuolo.

Bracciolini was born in 1380 at Terranuova near Arezzo in Tuscany. In 1862 his home village was renamed Terranuova Bracciolini in his honour.

He studied Latin as a young boy under a friend of the poet, Petrarch, and his linguistic ability and talent for copying manuscripts neatly was soon noted by scholars in Florence.

He later studied notarial law and was received into the notaries guild in Florence at the age of 21.

After becoming secretary to the Bishop of Bari, Bracciolini was invited to join the Chancery of Apostolic Briefs in the Roman Curia of Pope Boniface IX.

Part of one of Cicero's Catiline Orations copied by Bracciolini
 in a style of writing that became the basis for Roman fonts

He was to spend the next 50 years serving seven popes, first as a writer of official documents and then working his way up to becoming a papal secretary.

Bracciolini was well thought of because of his excellent Latin, beautiful handwriting and the diplomatic work he was able to carry out with Florence.

He was never attracted to the ecclesiastical life and its potential riches and, despite his poor salary, remained a layman to the end of his life.

He invented the style of writing that, after generations of polishing by other scribes, served the new art of printing as the prototype for Roman fonts.

In 1415 while working for the Pope at a monastery in Cluny, Bracciolini brought to light two previously unknown orations of the Roman statesman Cicero.

At another monastery in 1416 he found the first complete text of Quintilian’s Institutio oratoria, three books and part of a fourth of Valerius Flaccus’s Argonautica and the commentaries of Asconius Pedianus on Cicero’s orations.

in Florence, attributed to Donatello

While visiting other monasteries in 1417 he discovered a number of Latin manuscripts, including De rerum natura (On the Nature of Things) by Lucretius.

It is believed he subsequently discovered seven other orations of Cicero in a monastery in Cologne.

He made copies of the works he found in his elegant script, some of which have survived.

Bracciolini also collected classical inscriptions and sculptures, with which he adorned the garden of the villa he eventually bought near Florence.

At the age of 56 he left his long-term mistress and married a girl of 17, who produced five sons and a daughter for him.

He spent his last years having intellectual arguments with Lorenzo Valla, an expert at philological analysis of ancient texts, and writing a history of Florence.

Bracciolini died in 1459 before he had put the final touches to this work and was buried at the Church of Santa Croce in Florence.

The 2011 Pulitzer Prize winning book, The Swerve: How the World Became Modern by Stephen Greenblatt, tells the story of Bracciolini’s discovery of the ancient manuscript written by Lucretius. Greenblatt analyses the poem’s subsequent influence on the Renaissance, the Reformation and modern science.

 where Bracciolini was buried in illustrious company

Travel tip:

The Basilica of Santa Croce, consecrated in 1442, is the main Franciscan church in Florence and the burial place among others of Michelangelo, Galileo, Machiavelli, the poet Ugo Foscolo, the philosopher Giovanni Gentile and the composer Gioachino Rossini.  It houses works by some of the most illustrious names in the history of art, including Canova, Cimabue, Donatello, Giotto and Vasari.  The Basilica, with 16 chapels, many of them decorated with frescoes by Giotto and his pupils, is the largest Franciscan church in the world and the present building dates back to the 13th century.

The village of Terranuova Bracciolini, near Arezzo, where
Bracciolini was born and which was renamed in 1862

Travel tip:

Terranuova Bracciolini is a town in the province of Arezzo in Tuscany, located about 35km (22 miles) southeast of Florence and about 25m (16 miles) northwest of Arezzo.  Originally called Castel Santa Maria, the town was part of Florence’s massive 14th-century project to build new areas to populate in the countryside. It was renamed after Poggio Bracciolini in 1862.  Terranuova Bracciolini still conserves its medieval walls and some perimeter towers.
