Candidate passages:
Arts of the late 1400s and early 1500s were dominated by three men.
They were Michelangelo, Raphael, and Leonardo da Vinci.
Michelangelo excelled as a painter, architect, and poet.
In addition, he has been called the greatest sculptor in history.
Michelangelo was a master of portraying the human figure.
For example, his famous statue of the Israelite leader "Moses" (1516) gives an overwhelming impression of physical and spiritual power.
These qualities also appear in the frescoes of Biblical and classical subjects that Michelangelo painted on the ceiling of the Vatican's Sistine Chapel.
The frescoes, painted from 1508 to 1512, rank among the greatest works of Renaissance art.
Raphael's paintings are softer in outline and more poetic than those of Michelangelo.
Raphael was skilled in creating perspective and in the delicate use of color.
He painted a number of beautiful pictures of the Madonna (Virgin Mary) and many outstanding portraits.
One of his greatest works is the fresco "The School of Athens".
The painting was influenced by classical Greek and Roman models.
It portrays the great philosophers and scientists of ancient Greece in a setting of classical arches.
Raphael was thus making a connection between the culture of classical antiquity and the Italian culture of his time.
Leonardo da Vinci painted two of the most famous works of Renaissance art, the wallpainting "The Last Supper" and the portrait "Mona Lisa".
Leonardo had one of the most searching minds in all history.
He wanted to know how everything that he saw in nature worked.
In over 4,000 pages of notebooks, he drew detailed diagrams and wrote his observations.
Leonardo made careful drawings of human skeletons and muscles, trying to learn how the body worked.
Due to his inquiring mind, Leonardo has become a symbol of the Renaissance spirit of learning and intellectual curiosity.
The creator of High Renaissance architecture was Donato Bramante, who came to Rome in 1499, when he was 55.
His first Roman masterpiece, the "Tempietto" (1502) at San Pietro in Montorio, is a centralized dome structure that recalls Classical temple architecture.
Pope Julius II chose Bramante to be papal architect, and together they devised a plan to replace the 4th-century Old St. Peter's with a new church of gigantic dimensions.
The project was not completed, however, until long after Bramante's death.
Humanistic studies continued under the powerful popes of the High Renaissance, Julius II and Leo X, as did the development of polyphonic music.
The Sistine Choir, which performed at services when the pope officiated, drew musicians and singers from all of Italy and northern Europe.
Among the most famous composers who became members were Josquin des Prez and Giovanni Pierluigi da Palestrina. 
Comic books.
Mirage Comics.
In the original comic books, Michelangelo was initially depicted as fun-loving, carefree, and, while not as aggressive as Raphael, always ready to fight.
He is much more serious-natured in the comic book than in the film incarnations, which have labeled his character a permanent "dude" talking pre-teen.
It was Michelangelo's one-shot in this series that fleshed out most of the traits that have become synonymous with the character, such as his playfulness, empathy, and easygoing nature.
In the one-shot story, Michelangelo adopts a stray cat (which he names Klunk) and also stops thieves from stealing toys meant for orphaned children.
After their defeat at the hands of the Foot Clan the Turtles, Splinter, April O'Neil, and Casey Jones retreat to a farm house in Northampton, Massachusetts which used to belong to Casey's grandmother.
While there, April is worried to note that Michelangelo is not himself.
He spends his days in the barn taking out his aggression on a punching bag.
A scene shows him lashing out at his surroundings and repeatedly punching the wall of the barn until it breaks, then collapsing on it despondently, anger spent.
The end of the story implies that Michelangelo's sorrow and frustration have been resolved, as subsequent issues restore Michelangelo's more relaxed, optimistic personality.
It is during the group's time at the farm we learn that Michelangelo also has an interest in comic books, specifically ones involving superheroes such as "The Justice Force" (comic book heroes based on The Justice League and The Fantastic Four).
He also finds solace in writing fiction and has produced a story depicting himself as a ronin in Feudal Japan.
In the story arc "City at War", Michelangelo instantly bonds with Casey Jones' adopted daughter Shadow, who nicknames him "Rooish".
In the second volume, the Turtles decide to try to live apart from one another.
Michelangelo, the social creature that he is, moves in with April and Casey so that he can be close to Shadow.
Throughout the first two volumes, Michelangelo seemed to act as peacemaker of the team.
These stories also laid the foundations which demonstrated his closeness with Donatello, their laid-back natures separating them from the more contentious Leonardo and Raphael.
In Volume 4, Michelangelo gets a job as a tour guide showing alien visitors around Earth.
His first (and only) tourist is the "Regenta" (or "princess") Seri of the Styracodon race.
Michelangelo convinces Seri to sneak away from her bodyguards so that he can take her on a tour of the northwest coast of the USA.
Their relationship becomes more intimate apparently, when Seri delivers eggs that she claims are "their" children.
Unfortunately, before much time is given for him to settle with this news Seri's bodyguards become aware of his machinations.
They attack Michelangelo and transport him back to their home world, where he is placed in prison.
With the help of a Triceraton prisoner named Azokk, he manages to escape, and is rescued by a group of Triceratons who came to rescue Azokk.
Michelangelo was not given an especially large role in Volumes 1 and 2, did little to advance the plot, and was often not portrayed as an especially skilled fighter.
His relatively small role was probably due to the need to establish Leonardo's role as "leader" along with the fact that Donatello was Peter Laird's favorite Turtle, and Raphael was Kevin Eastman's favorite.
This incarnation of Michelangelo appeared in the "Turtles Forever" crossover special voiced by Braford Cameron. 
This period has been described as a 'natural extension' of the art of Andrea del Sarto, Michelangelo, and Raphael.
Michelangelo from early age has developed a style of his own, a deeply original style which was greatly admired first, then often copied and imitated by his fellow artists of his time.
One of the qualities most admired by his contemporaries was his "terribilità", a sense of awe-inspiring grandeur, and it was the attempts of subsequent artists to imitate.
Michelangelo's impassioned and highly personal style was thus learned by the other artists copying the works of the master, learning by copying was a standard way that students learn to paint and sculpt.
His Sistine Chapel ceiling provided examples for other artists to follow, in particular the figures of "ignudi" and of the Libyan Sibyl, his vestibule to the Laurentian Library, in the figures on his Medici tombs, and above all in his "Last Judgment".
The later Michelangelo was one of the great role model of Mannerism.
This was noticed by Michelangelo himself who might have been annoyed sometimes by this.
Young artist broke in into the house of Michelangelo and stole drawings from him.
In his book "Lives of the Most Eminent Painters, Sculptors, and Architects", Giorgio Vasari noted that Michelangelo stated once: "Those who are followers can never pass by whom they follow. 
Battle of the Centaurs is a relief by Italian Renaissance artist Michelangelo, created around 1492.
It was the last work Michelangelo created while under the patronage of Lorenzo de' Medici, who died shortly after its completion.
Inspired by a classical relief created by Bertoldo di Giovanni, the unfinished marble sculpture depicts the mythic battle between the Lapiths and the Centaurs.
A popular subject of art in ancient Greece, the story was suggested to Michelangelo by the classical scholar and poet Poliziano.
"Battle of the Centaurs" was a remarkable sculpture in several ways, presaging Michelangelo's future sculptural direction.
Michelangelo had departed from the then current practices of working on a discrete plane to work multidimensionally.
It was also the first sculpture Michelangelo created without the use of a bow drill and the first sculpture to reach such a state of completion with the marks of the subbia chisel left to stand as a final surface.
Whether intentionally left unfinished or not, the work is significant in the tradition of "non finito" sculpting technique for that reason.
Michelangelo regarded it as the best of his early works, and a visual reminder of why he should have focused his efforts on sculpture. 
 Brian Tochi as Leonardo Robbie Rist as Michelangelo Corey Feldman as Donatello Tim Kelleher as Raphael James Murray as Splinter Cast.
Voice cast.
Rist and Tochi (who did the voices of Michelangelo and Leonardo, respectively) are the only two voice actors to voice the same character throughout all three live-action "TMNT" movies.
However, Feldman voiced Donatello in both this and the first movie.
