Isabella d'Este

Biography

Isabella was born on Tuesday, 19 May 1474 at nine o'clock in the evening. Isabella's mother, Eleanor of Naples, wrote a letter to her friend Barbara Gonzaga describing the details of Isabella's birth in Ferrara. Eleanor was the daughter of Ferdinand I, the Aragonese King of Naples, and Isabella of Clermont.

One year later, on 29 June 1475, her sister Beatrice was born, and in 1476 and 1477 two brothers, Alfonso and Ferrante, were born. In 1479 and 1480 two more brothers were born: Ippolito and Sigismondo. Of all the children born into the family, Isabella is believed to have been the favourite.

In the year of her brother Ferrante's birth, Isabella was among the children of the family who travelled to Naples with her mother. When her mother returned to Ferrara, Isabella accompanied her, while the other two children remained in Naples for many years: Beatrice was adopted by her grandfather, and her little brother Ferrante was left under the tutelage of their uncle Alfonso.

Education

Due to her outstanding intellect, she often discussed the classics and the affairs of state with ambassadors. Isabella d'Este encouraged her humanist apologists, including Mario Equicola, to promote the view that female education and experience of the world could cultivate the prudence and strength of character necessary for political authority. In addition, she was personally acquainted with the painters, musicians, writers, and scholars who lived in and around the court. Besides her extensive knowledge of history and languages, she could also recite Virgil, Cicero and Terence by heart. In addition, she also had the ability to recite Latin and Greek grammar. After leaving Ferrara for Mantua, another former tutor, Jacopo Gallino, reminisced about teaching her, and sent her books they previously used together. While in Mantua, it appears she let go of studying Greek, but continued to study Latin. Isabella was also a talented singer and musician, and was taught to play the lute by Giovanni Angelo Testagrossa. In addition to these accomplishments, she was also an innovator of new dances, having been instructed in the art of dance by Ambrogio, a Jewish dancing master. Through her well-imbued lessons of a scholarly, classical, and artistic nature, Isabella later went on to apply these talents to her co-rule with her husband Francesco. By using these, she worked to solidify the way in which her presence and authority was seen, thus creating an image for herself and the Houses her family represented.

Betrothal and marriage

In 1480, at the age of six, Isabella was betrothed to the eight years older Francesco, the heir to the Marquess of Mantua. The Duke of Milan requested her hand in marriage for his son, Ludovico, two weeks later. Instead, her sister, Beatrice, was betrothed to Ludovico and became the Duchess of Milan. Her dowry amounted to 25,000 ducats. Although he was not handsome, Isabella admired Francesco for his strength and bravery; she also regarded him as a gentleman. After their first few encounters, she began to enjoy his company and she spent the next few years getting to know him and preparing to be the Marchioness of Mantua. During their courtship, Isabella treasured the letters, poems, and sonnets he sent her as gifts.

Ten years later, on 11 February 1490, at age 15, she married Francesco by proxy. By then, he had succeeded to the marquisate. Besides being the Marquess, Francesco was captain general of the armies of the Republic of Venice. Isabella became his wife amid a spectacular outpouring of public rejoicing and a grand celebration that took place on 15 February. She brought the sum of 3,000 ducats as her marriage portion, as well as valuable jewelry, dishes, and a silver service. Prior to the magnificent banquet which followed the wedding ceremony, Isabella rode through the main streets of Ferrara astride a horse draped in gems and gold. In addition, the couple were consistent in their correspondence, writing "la lettera missiva" to each other in order to further their familiarity following their union. Such letters ultimately detail the changes and developments of their relationship, each one composed and abiding by period-specific court conventions. Over the course of their marriage, there were a sizeable amount of letters sent between the couple. Their letters contained information about "political and administrative matters" but they also discussed the affection that they shared for one another in the letters from the beginning of their marriage.

In 1491, Isabella went with a small entourage to Brescello and from there to Pavia, to accompany her sister Beatrice, who was married to Ludovico il Moro. On this occasion, she saw Galeazzo Sanseverino again — as she had known him as a child in Ferrara — with whom she began a large, and at times humorous, exchange of letters. However, his identity is not certain and could be the almost homonymous Galeazzo Visconti, Count of Busto Arsizio, a courtier also dear to the dukes.

Between the two immediately ignited a dispute, destined to last for months, on who was the best paladin, Orlando or Rinaldo: Galeazzo supported the first, the sisters d'Este the second. Galeazzo, who exercised a strong fascination, soon managed to convert them both to Orlando's faith, but Isabella, once back in Mantua, returned to prefer Rinaldo, so that Galeazzo remembered her as "I alone was enough to make her change her mind and cry out Rolando! Rolando!", invited her to follow her sister's example and swore that he would convert her a second time, as soon as they met again. Isabella jokingly replied that she would then bring a frog to offend him, and the dispute went on for a long time.

Regency

Isabella played an important role in Mantua during troubled times for the city. When her husband was captured in 1509 and held hostage in Venice, she took control of Mantua's military forces and held off the invaders until his release in 1512. In the same year, 1512, she was the hostess at the Congress of Mantua, which was held to settle questions concerning Florence and Milan. As a ruler, she appeared to have been much more assertive and competent than her husband. When her husband was experiencing severe symptoms of his chronic syphilis, Isabella feared contracting the disease. To avoid this, Isabella decided to seek distractions outside of Mantua. She remained in Milan from 1513 to 1514. In this period, Isabella expressed a greater sense of maturation and independence, especially in her travels for diplomatic purposes. Isabella gained a better understanding of her political authority and broadened her cultural perspectives. She wrote frequently to her sick husband to both entertain him and to convey her seriousness as an advocate for Mantua while abroad. However, Francesco was skeptical about her travels and her image as a sophisticated diplomat. When Francesco learned in September 1514 that Isabella had gone to Genoa from Milan of her own accord, he reacted unfavourably. In response, Isabella wrote numerous letters to her husband asking for his forgiveness and apologising for her mistakes.Francesco was furious and humiliated at being surpassed by his wife's superior political ability. This caused their marriage to break down irrevocably. As a result, Isabella began to travel freely and live independently from her husband until his death on 19 March 1519. As years passed, Isabella's eldest son Federico, the new marquis of Mantua, grew tired of listening to his mother's political advice. Freed from this responsibility, Isabella decided to leave Mantua more often. She travelled to various cities, including Rome during the Sack of 1527, allowing her to stay in touch with new cultural and intellectual developments. Her pursuit of uncertain travels and sightseeing allowed her to live boldly, going against the submissive gender beliefs for her sex at the time and allowing her to embrace cosmopolitanism. During such travels, in December of 1514, Isabella visited Naples, also the birthplace of her mother, during her extended journey through Italy. The visit was arranged even though her husband, Francesco Gonzaga, was concerned about her absence from Mantua. These long periods of solo travel go to show Isabella's independence from her husband Francesco.

After the death of her husband, Isabella ruled Mantua as regent for her son Federico. She began to play an increasingly important role in Italian politics, steadily advancing Mantua's position. She was instrumental in promoting Mantua to a Duchy, which was obtained by wise diplomatic use of her son's marriage contracts. She also succeeded in obtaining a cardinalate for her son Ercole. She further displayed shrewd political acumen in her negotiations with Cesare Borgia, who had dispossessed Guidobaldo da Montefeltro, duke of Urbino, the husband of her sister-in-law and good friend Elisabetta Gonzaga in 1502

Widowhood

As a widow, Isabella at the age of 45 became a "devoted head of state". Her position as a Marquise required her serious attention, therefore she was required to study the problems faced by a ruler of a city-state. To improve the well-being of her subjects she studied architecture, agriculture, and industry, and followed the principles that Niccolò Machiavelli had set forth for rulers in his book The Prince. In return, the people of Mantua respected and loved her.

Isabella left Mantua for Rome in 1527. She was present during the catastrophic Sack of Rome, when she converted her house, the Palazzo Colonna, into an asylum for approximately 2,000 people (including clerics, nobles and common citizens) fleeing the Imperial soldiers. Her huge palace was the only place safe from attacks, because her son Ferrante Gonzaga was a general in the invading army and she herself had good relationship with the emperor. When she left Rome, she managed to acquire safe passage for all the refugees who had sought refuge in her home.

Once Rome became stabilized following the sacking, she left the city and returned to Mantua. She made it a centre of culture, started a school for girls, and turned her ducal apartments into a museum containing the finest art treasures. This was not enough to satisfy Isabella, already in her mid-sixties, so she returned to political life and ruled Solarolo, in Romagna. As her last large purchase, Isabella acquired the late Cardinal Sigismondo's countryside castle of Solarolo, in the territory of Faenza, and was responsible for overseeing improvements to the castle and maintaining well documented estate records. Following her death on 13 February 1539, Isabella was buried beside her husband in the Church of Santa Paola in Mantua, but her remains were stolen. French revolutionary troops in control of Mantua in 1797 tore apart the tombs in the Church of Santa Paola, including both her and her husband Francesco's tomb.

Appearance

Isabella's appearance was frequently written about in her lifetime. Mario Equicola said that "her eyes were black and sparkling, her hair yellow, and her complexion one of dazzling brilliancy." Similarly Gian Giorgio Trissino's I Ritratti has a fictionalized Pietro Bembo describe Isabella's "rippling golden hair that flowed in thick masses over her shoulders," in a passage that, according to art historian Sally Hickson, identifies Isabella as the "living paragon of female beauty." The real Bembo praised Isabella's "beautiful and charming hand and pure, sweet voice" in a letter addressed to her. The alleged beauty of Isabella attracted the attention of the king of France, Charles VIII, who asked the chaplain Bernardino of Urbino about her features and attempted to arrange a meeting with her. However, this meeting never took place as shortly after he returned to France.

Isabella herself frequently diminished her own appearance; commenting on his portrait she told Francia that he had "made us far more beautiful by your art than nature ever made us." Likewise she told Trissino that "your praises of us far exceed the truth", and said of Titian's portrait that "we doubt that at the age he represents us we were ever of the beauty it contains." In 1534, in the same year that Titian's portrait was painted, Titian's friend, Pietro Aretino, mocked her appearance, calling her "the monstrous Marchioness of Mantua, with ebony teeth and ivory eyelashes, dishonestly ugly and ultra-dishonestly tarted up." Despite her displays of modesty, Isabella was also known to lose herself in front of a mirror.

Isabella was worried about her weight from an early age. As an adult she discussed her weight with those close to her frequently. In 1499 she sent a portrait by Giovanni Santi to her brother Ludovico Sforza, complaining that it did not resemble her very much "for being a little fatter than me." Ludovico replied that he liked the portrait very much of her and that it was very similar to her, although "somewhat more fat", unless Isabella had "grown fatter after we saw her." In 1509 she complained to her husband that "if she had more to do with running the state she would not have grown fat", while in 1511 her sister Lucrezia complained about an early draft of the Francia portrait that made her look too thin.

Her face became damaged and prematurely aged by Venetian ceruse.

Legacy

During her lifetime and after her death, poets, popes, and statesmen paid tribute to Isabella. Pope Leo X invited her to treat him with "as much friendliness as you would your brother". The latter's secretary Pietro Bembo described her as "one of the wisest and most fortunate of women". The poet Ariosto deemed her the "liberal and magnanimous Isabella". Author Matteo Bandello wrote that she was "supreme among women", and the diplomat Niccolò da Correggio entitled her "The First Lady of the world".

Judgments less imbued with praise, indeed very harsh, were instead expressed by Pope Julius II in disagreement with Isabella's conduct, even went so far as to call her "that ribald whore". A similar judgment had also been expressed by her husband Francesco himself who, now a prisoner of the Venetians, accused his wife of not loving him and of having been the cause of his ruin, referring to her by letter as "that whore of my wife".

Cultural pursuits

Isabella d'Este is famous as the most important art patron of the Renaissance; her life is documented by her correspondence, which remains archived in Mantua (approximately 28,000 letters received and copies of approximately 12,000 letters written).

Art patronage

In painting she had numerous famous artists of the time work for her, including Giovanni Bellini, Giorgione, Leonardo da Vinci, Andrea Mantegna (court painter until 1506), Perugino, Raphael, Titian, Antonio da Correggio, Lorenzo Costa (court painter from 1509), Dosso Dossi, Francesco Francia, Giulio Romano, and many others. For instance her 'Studiolo' in the Ducal Palace, Mantua, was decorated with allegories by Mantegna, Perugino, Costa, and Correggio.

In parallel she contracted the most important sculptors and medallists of her time, i.e. Michelangelo, Pier Jacopo Alari Bonacolsi (L'Antico), Gian Cristoforo Romano, and Tullio Lombardo. She also collected ancient Roman art. Beyond her interest in paintings, sculptures, and medals, Isabella was dedicated to collecting antique gems, cameos, and other small, valuable objects, which she displayed in dedicated rooms. One of her most notable collections, however, was her istoriato maiolica service. Isabella collected maiolica from various cities, including Urbino, where her daughter Eleonora Gonzaga was duchess at the time. Eleonora, to smooth her relationship with her mother, commissioned the maiolica master Nicola da Urbino to provide Isabella with maiolica to decorate her palace at Porto. Isabella's maiolica service represents the genius of Nicola da Urbino; he detailed her maiolica with enigmatic emblems and narratives, such as the number XXVII, a number that means to overcome the arrows of misfortune. Urbino emphasized her humanist education and her role as a motherly figure of Mantua in the maiolica, decorating them with scenes that show how she protects her children, like in the Justice of Trajan. Urbino also decorated them with Roman gods, primarily Diana, as she represents female power and purity. Isabella d'Este's collection of mythological panel paintings set her apart from other Renaissance female patrons. Examining this type of patronage, scholars have drawn attention to her relationships with artists, including Mantegna, Bellini, and Perugino.

Isabella d'Este cultivated a richly scented environment: she was known for her scented gloves and kept vessels for perfumes and scented water in her Grota and Studiolo, which stood beside two gardens (Giardini d'Onore and Giardino Secreto) which were filled with these fragrant plants.

In music Isabella sponsored the composers Bartolomeo Tromboncino and Marco Cara and she played the lute. Unusually, she employed women as professional singers at her court, including Giovanna Moreschi, the wife of Marchetto Cara.

Personal adornment

Isabella established herself as an innovator in fashion, cosmetics, and interior styling, a reputation supported by records of her purchasing habits and art patronage. Beyond mere interest, she developed custom fragrances, swapped recipes for the court, and partnered with specialists to invent unique apparel and jewelry.

Literary patronage

For what concerns writers, she was in contact with Pietro Aretino, Ludovico Ariosto, Pietro Bembo, Baldassare Castiglione, Mario Equicola, Gian Giorgio Trissino, and others. While staying in contact with these writers, Isabella used literature for reading, collecting, display, gift exchange, and relationship-building. Isabella also relied on these personal connections to acquire new literary works, directly requesting from authors such as Matteo Maria Boiardo for recently written sections of his Orlando innamorato. Her library was unusually extensive for a woman of her period: a post-mortem inventory of Isabella's possessions listed 133 books, approximately half (66) of them manuscripts, with a relatively small proportion of devotional works compared with other elite women's collections.

Portraits

Despite her significant art patronage that included a number of portraits, there are very few surviving portraits that may be identified as Isabella, especially when compared to her sister Beatrice. It is known that the elderly Isabella preferred idealized paintings and even waived sitting as a model. However, it may be presumed that she insisted nonetheless on seeing her personal characteristics in the outcome. These few identifications are known as inhomogeneous (i.e. differing eye and hair colours as well as divergent eyebrows in two Titian portraits).

In 1495 she refused with absolute rigor to pose for Mantegna in the Madonna della Vittoria – where her figure was provided next to that of her husband – since in the past the painter had portrayed her "so badly done" – in a painting that in fact has not survived – "which has none of my similarities". However, the negative judgment of the Marquise was not due to Mantegna's inability to portray her similar to the truth, as she herself writes, but to the opposite lack: of not knowing how to "well counterfeit the natural", that is idealize. Her husband Francesco had to pose alone and Mantegna remedied the disturbance of the symmetry by painting, in place of the Marquise, St. Elizabeth, his eponymous saint.

In recent years several museums have withdrawn their few identifications of portraits as Isabella because of concern about possible misidentification.

The remaining three colourful portraits are still inhomogeneous (Kunsthistorisches Museum/KHM, Vienna):

Ambras Miniature, 16th century

Isabella in Red by Titian, c. 1529 (lost, known from a copy by Peter Paul Rubens c. 1605)

Isabella in Black by Titian, 1536

La Bella (now in Palazzo Pitti, Florence) has been discussed as an alternative to Titian's 1536 portrait in Vienna, because the commission from the 60-year-old patron was for a rejuvenated portrait; if La Bella were Isabella, eye colour, hair colour, eyebrows, and general appearance would homogenize in all known portraits, allowing potential links toward further identifications.

Relationship with Leonardo and Mona Lisa theory

In the current catalogue raisonné of Leonardo da Vinci (2019), only Isabella d'Este is documented as a plausible alternative as the subject of Leonardo's Mona Lisa, usually considered a portrait of Lisa del Giocondo. Lisa was the wife of a less known merchant in Florence and Giorgio Vasari wrote of her portrait by Leonardo, – in debate that persists about whether this is the portrait now known as the Mona Lisa. No visual comparisons are known for Lisa del Giocondo's and the format speaks in favour of a wealthy art patron.

Evidence in favor of Isabella as the subject of the famous work includes Leonardo's drawing 'Isabella d'Este' from 1499 and her letters of 1501–1506 requesting the promised painted portrait. Further arguments focus upon the mountains in the background indicating the native origin of the subject, and the armrest in the painting as a Renaissance symbol used to identify a portrait as that of a sovereign. The cleaned Prado copy from the Leonardo workshop also confirms the hairstyle shown on Isabella d'Este's portrait medals: hair tied up and temple curls. The Louvre's reservation was (in 1975) that Isabella would be a "blonde", a feature that exists only in the widely circulated but uncertain representation Isabella in Black.

Issue

Together Isabella and Francesco had eight children:

Eleonora Gonzaga (31 December 1493 – 13 February 1570), married Francesco Maria I della Rovere, Duke of Urbino, by whom she had issue

Margherita Gonzaga (13 July 1496 – 22 September 1496)

Federico II Gonzaga, Duke of Mantua (17 May 1500 – 28 August 1540), married Margaret Paleologa, by whom he had issue

Livia Gonzaga (1501 – January 1508)

Ippolita Gonzaga (13 November 1503 – 16 March 1570), who became a nun

Ercole Gonzaga (23 November 1505 – 2 March 1563), Cardinal, Bishop of Mantua

Ferrante Gonzaga (28 January 1507 – 15 November 1557), a condottiero; married Isabella di Capua, by whom he had issue

Livia Gonzaga (August 1508 – 1569), who became a nun

Household slaves

Correspondence exchanged by Isabella documents the Renaissance European tendency to perceive black African slaves as exotic. According to her extant correspondence, Isabella put considerable effort into bringing African children into her household. On May 1st, 1491, Isabella wrote to her agent in Venice, Giorgio Brognolo, to procure a young black girl between the ages of one-and-a-half and four. In two following reminders sent to Brognolo in early June, she emphasized that the girl be "as black as possible." In her correspondence with her sister-in-law, Anna Sforza, in late June 1491, they discussed their treatment of their very young black maidservants. This revealed that Isabella already possessed an older African girl—whom she referred to as the "best buffoon in the world." Later in June, Brognolo reported back that he had found a four-year-old black girl, who was a daughter of a free African gondolier in Venice. However, Isabella failed to acquire her as her mother, Eleonora d'Aragona, had already invited the girl and her family to enter the service of her household in Ferrara. Persisting in her search, Isabella procured two other black African children from Venice: one two-year-old girl from a Venetian orphanage, one boy from a Venetian patrician household. In 1497, she purchased a black girl from her sister-in-law Chiara Gonzaga.

Depiction in modern media

The artwork The Dinner Party by Judy Chicago features a place setting for Isabella d'Este.

Isabella d'Este was portrayed by Belgian actress Alexandra Oppo in the television show Borgia (2011–2014).

Isabella d'Este was depicted as a vampire in the video game Vampire Therapist (2024). The game chronicles Isabella's life and the fate of the Gonzaga house.

Isabella d'Este is the subject of a novel by the historian and bestselling novelist Sarah Dunant, The Marchesa, published by Whitefox in 2025, is based on her archive of letters in Mantua and includes illustrations. While ostensibly fiction, it is historically accurate.
