Question: When did Donatello go back to Florence?
About the article "Donatello", section "Last years in Florence".

Candidate passages:
 c.1400: Miniaturist Jacquemart de Hesdin paints "The Carrying of the Cross" 1401: Commission to design bronze doors for the Florence Baptistery won by Lorenzo Ghiberti 1408: Donatello commissioned to sculpt a marble "David" for Florence Cathedral, his first significant commission  
Donatello returned to Florence in 1453.
The Judith and Holofernes, begun for the Duomo di Siena date from 1455 to 1460 but were later acquired by the Medici.
Until 1461, Donatello remained in Siena, where he created a "St. John the Baptist", also for the Duomo, and models for its gates, now lost.
For his last commission in Florence, Donatello produced reliefs for the bronze pulpits in the church of San Lorenzo, with help from students Bartolomeo Bellano and Bertoldo di Giovanni.
Donatello provided the general design and personally executed the "Martyrdom of St. Lawrence" and the "Deposition from the Cross"; he worked on the reliefs of "Christ before Pilate" and "Christ before Caiphus", with Bellano.
This work is characterized by an intense, free, indeed sketchy and suggestively unfinished — in Italian a "non-finito" — technique that heightens the dramatic effect of the scenes and emphasizes their spiritual intensity.
Donatello died in Florence in 1466 and was buried in the Basilica of San Lorenzo, next to Cosimo de' Medici the Elder.
Mirage Comics.
In the comics, Donatello is originally presented along with Leonardo as one of the two calmer turtles.
While the comics portrayal of the team has no official command structure, in the early stories he is depicted as second-in-command.
In the first issue, he is the one that killed the Shredder by knocking him and his grenade off the roof.
The second issue elaborated more on each turtles' personalities and opened with Donatello soldering a circuit.
Later in the issue, Donatello states that he is "familiar with some computer systems" and helps April O'Neil deactivate the Mousers.
During the turtles' exile to Northampton, Donatello becomes obsessed with fixing up and repairing the many broken things within the farmhouse they were living in.
Most notably he spent days and nights fixing the boiler to give his family hot running water and builds a windmill and a water wheel to provide electricity.
He also finds an old type writer and writes his own personal credo.
In the Donatello one shot, Donatello encounters an artist called Kirby (an homage to the comic artist Jack Kirby) whose mysterious crystal brings his drawings to life before disappearing.
The two newfound friends journey to a dimension inhabited by Kirby's creations and help the heroes defeat the invading monsters.
In the "Shades of Grey" storyline, Casey Jones encounters the turtle by a ravine as he was pondering "the fractal structure of natural patterns".
Casey accuses the turtle of using big words and acting better than everyone else.
Donatello suggests they should continue the conversation when Casey is sober.
Grabbing a stick, an angry Jones continually pokes the turtle until he loses his temper and sends Casey careening into the water.
In the "City at War" storyline, the turtles return to New York to put an end to the Foot Clan's civil war.
During a battle with Shredder's Elite Guards in the ruins of the Second Time Around Shop, Donatello falls through the floor and breaks his leg.
Seeing their ally Karai subdued and about to be killed, Donatello grabs one of the Foot's machine guns and repeatedly shoots the Foot Elite.
Donatello is visibly shaken by the violence and throws the gun away.
At the end of the story the turtles, April and Casey move back to New York save for Donatello who chooses to stay in Northampton with Master Splinter to heal from his injury as well as reflect on everything that had happened.
While meditating with Splinter, Donatello receives a vision of the future where he is in the village of Chihaya in Japan.
When Donatello asks what he would be doing there, his master simply replies "To bury me".
After encountering the turtle vigilante ally Nobody in civilian guise he returns with him to New York to help his brothers battle Baxter Stockman.
In the current comics, Donatello finds an armored truck in the sewers which apparently had been part of a bank robbery in the sixties.
Along with Raphael and Casey Jones undertakes the task of fixing up the vehicle.
After the death of Splinter, Donatello secretly goes to his body and asks forgiveness before clipping something off him.
Shortly after, Donatello decides to accompany the Utroms on a mission to Tepui to search for two missing research teams.
The group are attacked by strange wooden creatures who shrink them to miniature size.
The creatures turn out to be a group of Utroms which had been stranded in the Jungle during their first stay on Earth and had been living in secret thanks to their Quantum Inversion Redimensioning device which could alter their size.
The process could not be reversed on Donatello, possibly due to his mutation, leaving him the size of an action figure.
While the Utroms work on returning him to normal, Donatello put his new size to use infiltrating a terrorist organizations warehouse.
He's also made a robotic body for him made to resemble a turtle to help him move around.
This incarnation of Donatello appeared in the "Turtles Forever" crossover special voiced by Christopher C. Adams. 
Like the Mirage comics, Donatello has a complex personality in the 2003 animated series.
Donatello is voiced by Sam Riegel in the original English version and Yuji Ueda in the Japanese version.
Several episodes concentrate on him, as well as his emotional and intellectual struggles.
As in his other incarnations, he is intelligent, good with his hands, and very introspective, frequently becoming pensive over things he doesn't understand.
He typically has a very close, however platonic, relationship with April.
He also displays closeness with Michelangelo akin to that seen in the original movie.
Even more pacifistic than his other incarnations, Donatello shows a greater interest in technology than his ninjutsu training.
Even so, Donatello will defend his brothers at any cost, and he frequently assists the team in many ways through the technology he develops, mostly vehicles and communication devices.
In this animation, Donatello is generally well liked by all of his brothers, never engaging in major confrontations with them.
In fact, Donatello was the one to reunite his brothers against the Shredder in the episode "Same As It Never Was", having been sent to an alternate future where the team fell apart after he vanished.
His skin color is a light, brownish green color; this particular color is only used for him in the 2003 animation.
In the fourth season, he was infected by a monster, and in the episode "Adventures in Turtlesitting", he mutates into a monster himself, which happened to Raphael in the comics.
In the seventh season, also called "Back to the Sewer", Donatello blamed himself for Master Splinter's decompiling and vowed to restore his bits from cyberspace.
This obsession caused him to disregard anything else, such as the war between the Purple Dragons and the Foot clan, as unimportant.
It wasn't until seeing his brothers in danger from the Cyber Shredder did he realize he was ignoring his responsibilities to help them and promised not to let his obsession with saving Master Splinter take control again.
By the time of "Turtles Forever", the 2003 Donatello is in total disbelief over the scientific attitude of his 1987 counterpart, in which the alternate Donatello replied, "Science isn't all just facts and figures", although the two still manage to work together to track their enemies. 
In 2012 and 2013, De Fauveau’s Sepulcher for Louise de Favreau and Monument to Anne de la Pierre were at the center of a restoration and maintenance project sponsored by the Advancing Women Artists Foundation (AWA).
Both monuments had been damaged when the Arno River flooded Florence in 1966.
With regards to the first restoration, author and AWA Founder Jane Fortune writes, ‘Restorers had the opportunity to discover more about de Fauveau’s sculptural methods which differed from those of her contemporaries who were intent on copying Donatello.
She used flat and toothed chisels to create linear movement and most likely learned carving techniques by working on medallions.’ The artist’s base-relief of Florence behind the figure of de Favreau is an example of her technique.
During the restoration of De Fauveau’s monument in Santa Maria del Carmine, restorers replaced Anne de la Pierre’s chin, damaged during the Nazi invasion of Florence in 1943.
