The Quartiere Degli Dei Terrestri

The Studiolo of Francesco I:

Francesco de’ Medici, Duke Cosimo’s eldest son, commissioned Giorgio Vasari to design this room, located off the Hall of the Five Hundred. Francesco used it as his study as well as to house family heirlooms, as was typical at the time (during the 16th and 17th century, collecting and categorizing objects was in vogue, influenced, no doubt, by the beginnings of the scientific revolution). Each side of the room was designed to resemble one of the four elements, which then corresponded to the items held within each built-in cabinet. The doors to those cabinets were also designed with the particular cabinet’s contents in mind, decorated with Biblical, mythological, or historical events that corresponded to its inner treasures.

The room’s apotheosis is the vault, which depicts Nature handing a stone to Prometheus. Nature’s handoff of the stone demonstrates the convergence of science and art (two of Francesco’s passions) because, it is assumed, Prometheus will transform the stone into a beautiful gem. Prometheus is depicted holding a flaming branch because it was he, according to the greek writer Hesiod, who gave man the secret of fire. Zeus retaliated by chaining Prometheus to a mountain and ordering an eagle to eat Prometheus’ liver, which would then regrow every night only to be eaten the next day. For men’s punishment in Prometheus’ scheme, Zeus allegedly created women.

[600] even so Zeus who thunders on high made women to be an evil to mortal men, with a nature to do evil. And he gave them a second evil to be the price for the good they had: whoever avoids marriage and the sorrows that women cause, and will not wed, reaches deadly old age [605] without anyone to tend his years, and though he at least has no lack of livelihood while he lives, yet, when he is dead, his kinsfolk divide his possessions amongst them. And as for the man who chooses the lot of marriage and takes a good wife suited to his mind, evil continually contends with good; [610] for whoever happens to have mischievous children, lives always with unceasing grief in his spirit and heart within him; and this evil cannot be healed. So it is not possible to deceive or go beyond the will of Zeus: for not even the son of Iapetus, kindly Prometheus, [615] escaped his heavy anger, but of necessity strong bands confined him, although he knew many a wile.

It seems Hesiod did not have much luck in his love life.

Surrounding the center fresco is a typical 16th century cosmogram (i.e. the four elements, the four qualities (cold, damp, hot, dry), the four humours (melancholic, phlegmatic, sanguine, and choleric), and the four seasons).

The Quartiere Degli Dei Terrestri

Also next to the Hall of the Five Hundred are apartments that were dedicated to housing guests of the Medici. In light of this function, Cosimo I commissioned Vasari to decorate the rooms with typical ducal trappings of power. Vasari did just that – and more. Rather than simply celebrate ducal power, the rooms serve to equate the Medici to “Dei Terrestri” (“earthly gods”).

Indeed, each room is dedicated to one of the Medici heroes, with frescoes celebrating major events of his lifetime. Each of these lower level rooms, however, corresponds to the room located directly above, which was dedicated to a mythical god and/or hero (the “Dei Celetri”). Through this linkage, Vasari mythologizes Cosimo’s more famous ancestors, elevating them to Dei Terrestri.

Room of Cosimo il Vecchio

The first room is dedicated to Cosimo il Vecchio (also known as “Pater Patriae” or “father of the nation”), arguably the most famous member of the Medici Family and Duke Cosimo’s namesake. Vasari decided to focus the room on Cosimo’s return from a year long exile in 1434.

Cosimo the Elder Returns from Exile, Giorgio Vasari

The ceiling fresco depicts throngs of Florentines meeting Cosimo as he returns to Florence, a depiction which would seem more appropriate for a triumphal return from battle rather than a return from exile. By emphasizing the people’s happiness over Cosimo’s return, however, Vasari refocuses the story on Cosimo’s popularity with the people rather than on the treason of which he was found guilty.

How did the Pater Patriae get himself exiled from the nation he had allegedly birthed? To understand, it is important to note that Florentine politics were rife with violence, internal conflict, mistrust, and petty jealousies. Indeed, Cosimo’s exile can be boiled down to one faction’s animosity towards the Medici’s increasing wealth and power. Rinaldo degli Albizzi and his conservative allies had been in control of Florence’s government for four decades when the Medici family was just beginning to assert its power. As the Medici attained more wealth and supporters, known as amici (translated as “friends”), tensions with the Albizzi grew. It all came to a head in 1429 when hostilities broke out between Florence and the city of Lucca. Albizzi and his conservatives favored a full blown war with Lucca while the Medici and the amici cautioned against it. The Albizzi won out and Florence went to war, which turned out to be a fiasco. As the costs of the war began mounting, Cosimo’s bank loaned the city money to cover the shortfall, eventually loaning Florence so much money that one third of the city’s debt was financed by the Medici bank. The result of this debacle was the people’s loss of confidence in Albizzi and an increase in respect for the Medici, who, as the Medici propagandists argued, had counseled against the war yet still risked financial ruin for the good of the republic to ensure its victory.

To avoid losing any more power and perhaps to save face, Albizzi tried Cosimo for treason, alleging Cosimo had prolonged the war for his own financial benefit. Cosimo was found guilty and subjected to exile, which, to Albizzi’s horror, was overturned after the election of a majority of amici to the Signoria. In an about-face, the newly elected Signoria brought Cosimo home and exiled Albizzi and many of his allies, purging the government of all those opposing the Medici and allowing Cosimo to take full control of the government. And so began the Medici’s tight hold on Florentine government (aside from a couple more periods of exile).

To improve their social standing both within Florence and without, the Medici family portrayed themselves as “renaissance men,” i.e. patrons of the arts, sciences, and culture. Vasari sought to capture Cosimo’s renown for artistic patronage in the painting below, Cosimo the Elder Surrounded by Literati and Artists, painted by Marco da Faenza (a collaborator to Vasari).

Here, Cosimo il Vecchio is depicted surrounded by key artists of his time, including Marsilio Ficino, Donatello, Filippo Brunelleschi, Luca della Robbia, Fra Angelico, Filippo Lippi, and Lorenzo Ghiberti, many of whom he had commissioned numerous artworks.

Room of Lorenzo il Magnifico

The next room is dedicated to Lorenzo il Magnifico, Cosimo’s grandson. Lorenzo’s father, known as Piero the Gouty, delegated much of the family authority to Lorenzo due to his poor health, Moreover, he was not as politically astute as his father or son, thus his lack of a room.

The second day after [my father’s] death, although I, Lorenzo was very young, being only twenty years of age, the principal men of the city and of the State came to us in our house to condole with us on our loss and to encourage me to take charge of the city and of the State, as my grandfather and my father had done.

Lorenzo de’Medici, Ricordi

In contrast to his father, Lorenzo operated on an international stage, thereby expanding the family’s influence beyond the bounds of Tuscany. It is therefore fitting that the ceiling in this room depicts foreign dignitaries presenting Lorenzo with gifts, including lions, Barb horses, jewels, and a cardinal hat, which was given to his son Giovanni, the first Medici to become pope.

Lorenzo was a living representation of the Medici’s move from solidly middle class stock to nobility. Indeed, Lorenzo’s wife, Clarice Orsini, came from an ancient Roman family, a match which was notable both for the bride’s foreignness and for her blue blood. Moreover, Lorenzo successfully lobbied for a cardinalship for his son, Giovanni de’Medici (later, Pope Leo X). With Giovanni’s cardinal’s hat, Lorenzo’s son was now a prince of the church, giving him the same status as any lay prince. Lorenzo had elevated his family from its commercial roots to nobility (via his wife Clarice), then royalty (via his son Giovanni).

This [hat] was a ladder enabling his family to rise to heaven.


Lorenzo also continued his grandfather’s patronage of the arts and sciences. In the painting to the right, he is depicted sitting amongst such humanists as Pico della Mirandola, Politian, Marsilio Ficino, Leon Battista Alberti, and Leonardo Bruni. Indeed, Lorenzo himself was an amateur philosopher and poet.

Interestingly, in both of these rooms, Vasari depicted Cosimo and Lorenzo in strikingly similar poses to that taken by Roman Emperor Constantine in the Aurelian Relief known as Liberalitas (located on the Arch of Constantine in Rome), further strengthening the link of the Medici to royalty/power. In the Liberalitas, Constantine is shown distributing money and protection to Roman citizens. So too, Vasari’s designs proclaim, Cosimo and Lorenzo distributed money and protection to the artists and intellectuals that surrounded them.

Room of Leo X

In my distress I cried unto the Lord, and he heard me.

Pope Leo X’s motto, taken from Psalm 120

Pope Leo X was born Giovanni de’ Medici, son of Lorenzo il Magnifico. He became a cardinal at thirteen (at this time it was common to be made a cardinal prior to attaining adulthood and even prior to taking holy orders) and was eventually elected to the papacy in 1513 (at age 37), taking the name Leo X (after the Florentine lion).

The Election of Giovanni de’Medici to the Papacy, Vasari

The piece below captures Pope Leo X’s visit to Florence in 1515. The procession into Florence was led by eighty mules and was rumored to have over 3,000 participants, including mace-bearers, squires, valets, secretaries, lawyers, ambassadors, cardinals, archbishops, and trumpeters.

The Arrival of Leo X in Florence, Vasari

Since the pope had left Rome to go to Bologna to meet the king of France … Leo decided that on the way he would pass through Florence to show his homeland the glory and grandeur God had vested in him, after so many different vicissitudes.

Vasari, Ragionamenti

Unfortunately, the rooms dedicated to Clement VII, Giovanni delle Bande Nere, and Cosimo I are not open to the public, as they are used as the offices of the mayor of Florence, so I don’t have any pictures, but I can tell you about them.

First, there is a room dedicated to Clement VII, the second Medici to hold the papal throne, who was elevated to the cardinalship by his uncle, Pope Leo X. He was elected to the papacy in November of 1523, and it was under his papacy that Holy Roman Emperor Charles V sacked Rome and the advent of the Protestant reformation. He, however, was the one responsible for installing the Medici as Dukes of Florence in the person of his illegitimate son, Alessandro de’Medici, via his alliance with Charles V, who had recently taken over the city.

The next room is dedicated to Giovanni delle Bande Nere, Cosimo I’s father. Giovanni was a commander in the papal army, serving under both his cousins Leo X and Clement VII. He died, likely from gangrene, after being wounded during a skirmish against Imperial troops. Upon Giovanni’s marriage to Maria Salviati (granddaughter to Lorenzo il Magnifico), the two branches of the Medici family were reunited.

Finally, Cosimo I dedicated a room wholly to none other than Cosimo I, thereby including himself among the legendary Medici heroes. A clear indication of how highly he thought of his political prowess.

Cosimo I became duke after his cousin, Duke Alessandro, made himself highly unpopular during his short-lived reign as Duke of Florence. Indeed, he was assassinated by another Medici cousin, Lorenzino, in January of 1537. Rather than install Alessandro’s illegitimate four year old son as duke, the Florentines promoted Cosimo as Alessandro’s successor. Charles V agreed and invested him with the duchy. It was Cosimo who lobbied Pope Pius V to grant the Medici the title of Grand Duke of Tuscany, a royal elevation from the (“simple”) dukedom of Florence.
