Candidate passages:
Lorenzo de' Medici's death on April 8, 1492, brought a reversal of Michelangelo's circumstances.
Michelangelo left the security of the Medici court and returned to his father's house.
In the following months he carved a wooden crucifix (1493), as a gift to the prior of the Florentine church of Santo Spirito, who had permitted him some studies of anatomy on the corpses of the church's hospital.
Between 1493 and 1494 he bought a block of marble for a larger than life statue of Hercules, which was sent to France and subsequently disappeared sometime around the 18th century.
On January 20, 1494, after heavy snowfalls, Lorenzo's heir, Piero di Lorenzo de' Medici commissioned a snow statue, and Michelangelo again entered the court of the Medici.
The Medici sixty year reign came to an end under the reign of Piero Medici.
In the same year, the Medici's were expelled from Florence as the result of the rise of Girolamo Savonarola.
Michelangelo left the city before the end of the political upheaval, moving to Venice and then to Bologna, where he stayed for more than a year.
In Bologna he was commissioned to finish the carving of the last small figures of the Shrine of St. Dominic, in the church dedicated to that saint.
According to Condivi, Lorenzo di Pierfrancesco de' Medici, for whom Michelangelo had sculpted St. John the Baptist, asked that Michelangelo "fix it so that it looked as if it had been buried" so he could "send it to Rome...pass off as an ancient work and...sell it much better."
Both Lorenzo and Michelangelo were unwittingly cheated out of the real value of the piece by a middleman.
Cardinal Raffaele Riario, to whom Lorenzo had sold it, discovered that it was a fraud, but was so impressed by the quality of the sculpture that he invited the artist to Rome.
This apparent success in selling his sculpture abroad as well as the conservative Florentine situation may have encouraged Michelangelo to accept the prelate's invitation.
Towards the end of 1494, the political situation in Florence was calmer.
Upon his return to Florence, he found that things in the city had greatly changed.
The city, previously under threat from the French, was no longer in danger as Charles VIII had suffered defeats.
Michelangelo returned to Florence but received no commissions from the new city government under Savonarola.
He returned to the employment of the Medici.
During the half year he spent in Florence he worked on two small statues, a child St. John the Baptist and a sleeping Cupid. 
After Alfieri's death Louise's companion was the artist François Xavier Fabre; it seems unlikely that their relationship was a romantic one.
Louise continued to live in Florence until in 1809 she was summoned to Paris by Napoleon who asked if she and Charles Edward had ever given birth to a child hoping they could then be used to try and stir up insurrection in Britain with which France was at war.
When she replied "no", the meeting was abruptly terminated.
A year later she was allowed to return to Florence.
Louise is buried in the Basilica di Santa Croce in Florence (in the Castellani Chapel); Alfieri is also buried in the basilica (between the tombs of Machiavelli and Michelangelo). 
  Michelangelo is appointed to reconstruct the fortifications of Florence.  
The Giardino dell'Iris is a botanical garden specializing in the cultivation of iris flowers, symbol of Florence since 1251.
It is located on the corner of Viale dei Colli and Piazzale Michelangelo in Florence, Italy, and open daily without charge from May 2-20 every year.
The garden is owned by the Società italiana dell'Iris, which has opened the garden to the public since hosting the annual "International dell'Iris" in 1954.
It is almost entirely devoted to iris plants, with more than 1,500 (variously 2,500) varieties on display during the annual competition.
The garden contains a pond is for the cultivation of aquatic varieties and provides an excellent view of Florence and its surrounding hills. 
Lorenzo de' Medici's death on 8 April 1492 brought a reversal of Michelangelo's circumstances.
Michelangelo left the security of the Medici court and returned to his father's house.
In the following months he carved a polychrome wooden "Crucifix" (1493), as a gift to the prior of the Florentine church of Santo Spirito, which had permitted him some studies of anatomy on the corpses of the church's hospital.
Between 1493 and 1494 he bought a block of marble, and carved a larger than life statue of Hercules, which was sent to France and subsequently disappeared sometime circa 18th century.
On 20 January 1494, after heavy snowfalls, Lorenzo's heir, Piero de Medici, commissioned a snow statue, and Michelangelo again entered the court of the Medici.
In the same year, the Medici were expelled from Florence as the result of the rise of Savonarola.
Michelangelo left the city before the end of the political upheaval, moving to Venice and then to Bologna.
In Bologna, he was commissioned to carve several of the last small figures for the completion of the Shrine of St. Dominic, in the church dedicated to that saint.
At this time Michelangelo studied the robust reliefs carved by Jacopo della Quercia around main portal of the Basilica of St Petronius, including the panel of "The Creation of Eve" the composition of which was to reappear on the Sistine Chapel ceiling.
Towards the end of 1494, the political situation in Florence was calmer.
The city, previously under threat from the French, was no longer in danger as Charles VIII had suffered defeats.

Michelangelo arrived in Rome 25 June 1496 at the age of 21.
On 4 July of the same year, he began work on a commission for Cardinal Raffaele Riario, an over-life-size statue of the Roman wine god "Bacchus".
Upon completion, the work was rejected by the cardinal, and subsequently entered the collection of the banker Jacopo Galli, for his garden.
In November 1497, the French ambassador to the Holy See, Cardinal Jean de Bilhères-Lagraulas, commissioned him to carve a "Pietà", a sculpture showing the Virgin Mary grieving over the body of Jesus.
The subject, which is not part of the Biblical narrative of the Crucifixion, was common in religious sculpture of Medieval Northern Europe and would have been very familiar to the Cardinal.
The contract was agreed upon in August of the following year.
Michelangelo was 24 at the time of its completion.
It was soon to be regarded as one of the world's great masterpieces of sculpture, "a revelation of all the potentialities and force of the art of sculpture".
Contemporary opinion was summarized by Vasari: "It is certainly a miracle that a formless block of stone could ever have been reduced to a perfection that nature is scarcely able to create in the flesh."
It is now located in St Peter's Basilica.
