The biggest accomplishments of the Medici were in the sponsorship of art and architecture, mainly early and High Renaissance art and architecture.
The Medici were responsible for the majority of Florentine art during their reign.
Their money was significant because during this period, artists generally only made their works when they received commissions in advance.
Giovanni di Bicci de' Medici, the first patron of the arts in the family, aided Masaccio and commissioned Brunelleschi for the reconstruction of the Basilica of San Lorenzo, Florence in 1419.
Cosimo the Elder's notable artistic associates were Donatello and Fra Angelico.
The most significant addition to the list over the years was Michelangelo Buonarroti (1475–1564), who produced work for a number of Medici, beginning with Lorenzo the Magnificent, who was said to be extremely fond of the young Michelangelo, inviting him to study the family collection of antique sculpture.
Lorenzo also served as patron to Leonardo da Vinci (1452–1519) for seven years.
Indeed Lorenzo was an artist in his own right, and author of poetry and song; his support of the arts and letters is seen as a high point in Medici patronage.
After Lorenzo's death the puritanical Dominican friar, Girolamo Savonarola rose to prominence, warning Florentines against excessive luxury.
Under Savonarola's fanatical leadership, many great works were "voluntarily" destroyed in the Bonfire of the Vanities (February 7, 1497).
The following year, on May 23, 1498, Savonarola and two young supporters were burned at the stake in the Piazza della Signoria, the same location as his bonfire.
In addition to commissions for art and architecture, the Medici were prolific collectors and today their acquisitions form the core of the Uffizi museum in Florence.
In architecture, the Medici are responsible for some notable features of Florence; including the Uffizi Gallery, the Boboli Gardens, the Belvedere, and the Palazzo Medici, Medici ChapelLater, in Rome, the Medici Popes continued in the family tradition of patronizing artists in Rome.
Pope Leo X would chiefly commission works from Raphael.
Pope Clement VII commissioned Michelangelo to paint the altar wall of the Sistine Chapel just before the pontiff's death in 1534.
Eleanor of Toledo, princess of Spain and wife of Cosimo I the Great, purchased the Pitti Palace from Buonaccorso Pitti in 1550.
Cosimo in turn patronized Vasari who erected the Uffizi Gallery in 1560 and founded the Accademia delle Arti del Disegno – ("Academy of the Arts of Drawing") in 1563.
Marie de' Medici, widow of Henry IV of France and mother of Louis XIII, is the subject of a commissioned cycle of paintings known as the Marie de' Medici cycle, painted for the Luxembourg Palace by court painter Peter Paul Rubens in 1622-23.
Although none of the Medici themselves were scientists, the family is well known to have been the patrons of the famous Galileo Galilei, who tutored multiple generations of Medici children, and was an important figurehead for his patron's quest for power.
Galileo's patronage was eventually abandoned by Ferdinando II, when the Inquisition accused Galileo of heresy.
However, the Medici family did afford the scientist a safe haven for many years.
Galileo named the four largest moons of Jupiter after four Medici children he tutored, although the names Galileo used are not the names currently used.

The Medici giraffe was a giraffe presented to Lorenzo de' Medici in 1486 possibly by al-Ashraf Qaitbay, the Burji Sultan of Egypt, in an attempt to win the support of the Medici.
It caused a great stir on its arrival in Florence: although the Medici maintained a large menagerie, and had previously featured a giant mannequin of a giraffe in the animal entertainments they provided to the citizenry, this was the first time a living example had been seen in the city.
It was also reputedly the first living giraffe to be seen in Italy since the days of Ancient Rome.
It did not survive for long and another giraffe was not seen in Europe for almost 300 years.
