Document 6: Michelangelo: A number of Michelangelo's works of painting, sculpture and architecture rank among the most famous in existence. His output in these fields was prodigious; given the sheer volume of surviving correspondence, sketches and reminiscences, he is the best - documented artist of the 16th century. He sculpted two of his best - known works, the Pietà and David, before the age of thirty. Despite holding a low opinion of painting, he also created two of the most influential frescoes in the history of Western art: the scenes from Genesis on the ceiling of the Sistine Chapel in Rome, and The Last Judgment on its altar wall. His design of the Laurentian Library pioneered Mannerist architecture. At the age of 74, he succeeded Antonio da Sangallo the Younger as the architect of St. Peter's Basilica. He transformed the plan so that the western end was finished to his design, as was the dome, with some modification, after his death.
Document 7: Artemisia Gentileschi: Artemisia Gentileschi was born Artemisia Gentileschi Lomi in Rome on July 8, 1593, although her birth certificate from the Archivio di Stato indicated she was born in 1590, the eldest child of the Tuscan painter Orazio Gentileschi and Prudenzia di Ottaviano Montoni. Artemisia was introduced to painting in her father's workshop, showing much more talent than her brothers, who worked alongside her. She learned drawing, how to mix color, and how to paint. "By 1612, when she was not yet nineteen years old, her father could boast of her extraordinary talents, claiming that in the profession of painting, which she had practiced for three years, she had no peer".
Document 8: Vittoria Colonna: Colonna was born at Marino in 1490, a fief of the Colonna family in the Alban Hills near Rome.

She was engaged in 1495 at the age of 3 years old to "Ferrante" Fernando Francesco d'Ávalos, son of the marquese di Pescara, at the insistence of Ferdinand, King of Naples.
Document 9: Michelangelo: Michelangelo was born on 6 March 1475 in Caprese, known today as Caprese Michelangelo, a small town situated in Valtiberina, near Arezzo, Tuscany. For several generations, his family had been small-scale bankers in Florence; but the bank failed, and his father, Ludovico di Leonardo Buonarroti Simoni, briefly took a government post in Caprese, where Michelangelo was born. At the time of Michelangelo's birth, his father was the town's Judicial administrator and podestà or local administrator of Chiusi della Verna. Michelangelo's mother was Francesca di Neri del Miniato di Siena. The Buonarrotis claimed to descend from the Countess Mathilde of Canossa—a claim that remains unproven, but which Michelangelo believed.Several months after Michelangelo's birth, the family returned to Florence, where he was raised. During his mother's later prolonged illness, and after her death in 1481 (when he was six years old), Michelangelo lived with a nanny and her husband, a stonecutter, in the town of Settignano, where his father owned a marble quarry and a small farm. There he gained his love for marble. As Giorgio Vasari quotes him:

Her father's parents were immigrants from Pacentro, Italy, while her mother was of French-Canadian ancestry. Tony worked as an engineer designer for Chrysler and General Motors. Since Madonna had the same name as her mother, family members called her "Little Nonni". She has two elder brothers, Anthony (born 1956) and Martin (born 1957), and three younger siblings, Paula (born 1959), Christopher (born 1960), and Melanie (born 1962).

Document 13: Lionel Messi: Lionel Andrés Messi was born on 24 June 1987 in Rosario, the third of four children of Jorge Messi, a steel factory manager, and his wife Celia Cuccittini, who worked in a magnet manufacturing workshop. On his father's side, he is of Italian and Spanish descent, the great-grandson of immigrants from the northcentral Adriatic Marche region of Italy and Catalonia, and on his mother's side, he has primarily Italian ancestry. Growing up in a tight-knit, football-loving family, "Leo" developed a passion for the sport from an early age, playing constantly with his older brothers, Rodrigo and Matías, and his cousins, Maximiliano and Emanuel Biancucchi, both of whom became professional footballers. At the age of four he joined local club Grandoli, where he was coached by his father, though his earliest influence as a player came from his maternal grandmother, Celia, who accompanied him to training and matches. He was greatly affected by her death, shortly before his eleventh birthday; since then, as a devout Catholic, he has celebrated his goals by looking up and pointing to the sky in tribute of his grandmother.
