Mona Lisa

The title of the painting, which is known in English as Mona Lisa, is based on the presumption that it depicts Lisa del Giocondo, although her likeness is uncertain. Renaissance art historian Giorgio Vasari wrote that "Leonardo undertook to paint, for Francesco del Giocondo, the portrait of Mona Lisa, his wife." Monna in Italian is a polite form of address originating as ma donna—similar to Ma'am, Madam, or my lady in English. This became madonna, and its contraction monna. The title of the painting is spelled in Italian as Monna Lisa (mona being a vulgarity in Italian), which is rare in English, where it is traditionally spelled Mona.

Lisa del Giocondo was a member of the Gherardini family of Florence and Tuscany, and the wife of wealthy Florentine silk merchant Francesco del Giocondo. The painting is thought to have been commissioned for their new home, and to celebrate the birth of their second son, Andrea. The Italian name for the painting, La Gioconda, means "jocund" ("happy" or "jovial"), or literally "the jocund one", a pun on the feminine form of Lisa's married name, Giocondo. In French, the title La Joconde has the same meaning. Vasari's account of the Mona Lisa comes from his biography of Leonardo published in 1550, 31 years after the artist's death. It has long been the best-known source of information on the provenance of the work and identity of the sitter. Leonardo's assistant Salaì, at his death in 1524, owned a portrait which in his personal papers was named la Gioconda, a painting bequeathed to him by Leonardo.

That Leonardo painted such a work, and its date, were confirmed in 2005 when a scholar at Heidelberg University discovered a marginal note in a 1477 printing of a volume by ancient Roman philosopher Cicero. Dated October 1503, the note was written by Leonardo's contemporary Agostino Vespucci. This note likens Leonardo to renowned Greek painter Apelles, who is mentioned in the text, and states that Leonardo was at that time working on a painting of Lisa del Giocondo. In response to the announcement of the discovery of this document, Vincent Delieuvin, the Louvre representative, stated "Leonardo da Vinci was painting, in 1503, the portrait of a Florentine lady by the name of Lisa del Giocondo. About this we are now certain. …

The Mona Lisa bears a strong resemblance to many Renaissance depictions of the Virgin Mary, who was at that time seen as an ideal for womanhood. The woman sits markedly upright in a pozzetto armchair with her arms folded, a sign of her reserved posture. Her gaze is fixed on the observer. The woman appears alive to an unusual extent, which Leonardo achieved by his method of not drawing outlines. The soft blending (sfumato) creates an ambiguous mood "mainly in two features: the corners of the mouth, and the corners of the eyes".

The depiction of the sitter in three-quarter profile is similar to late 15th-century works by Lorenzo di Credi and Agnolo di Domenico del Mazziere. Frank Zöllner notes that the sitter's general position can be traced back to Flemish models and that "in particular the vertical slices of columns at both sides of the panel had precedents in Flemish portraiture." Woods-Marsden cites Hans Memling's portrait of Benedetto Portinari (1487) or Italian imitations such as Sebastiano Mainardi's pendant portraits for the use of a loggia, which has the effect of mediating between the sitter and the distant landscape, a feature missing from Leonardo's earlier portrait of Ginevra de' Benci.

The painting was one of the first Italian portraits to depict the sitter in front of an imaginary landscape, although some scholars favour a realistic description, and Leonardo was one of the first painters to use aerial perspective. The enigmatic woman is portrayed seated in what appears to be an open loggia with dark pillar bases on either side. Behind her, a vast landscape recedes to icy mountains, winding paths and a distant bridge, giving only the slightest indications of human presence. Leonardo chose to place the horizon line not at the neck, as he did with Ginevra de' Benci, but on a level with the eyes, thus linking the figure with the landscape and emphasizing the mysterious nature of the painting. The bridge in the background was identified by Silvano Vincenti as the four-arched Romito di Laterina bridge from Etruscan-Roman times near Laterina, Arezzo, over the Arno river. Other bridges with similar arches suggested as possible locations had more arches. Some observers find similarities with the Azzone Visconti Bridge.

Mona Lisa has no clearly visible eyebrows or eyelashes, although Vasari describes the eyebrows in detail. …

Of Leonardo da Vinci's works, the Mona Lisa is the only portrait whose authenticity has never been seriously questioned, and one of four works‍—‍‌the others being Saint Jerome in the Wilderness, Adoration of the Magi and The Last Supper⁠ —‍‌whose attribution has avoided controversy. He had begun working on a portrait of Lisa del Giocondo, the sitter for the Mona Lisa, by October 1503. It is believed by some that the Mona Lisa was begun in 1503 or 1504 in Florence. Although the Louvre states that it was "doubtless painted between 1503 and 1506", art historian Martin Kemp says that there are some difficulties in confirming the dates with certainty. Alessandro Vezzosi believes that the painting is characteristic of Leonardo's style in the final years of his life, post-1513. Other academics argue that, given the historical documentation, Leonardo would have painted the work from 1513. According to Vasari, "after he had lingered over it four years, [he] left it unfinished". In 1516, Leonardo was invited by King Francis I to work at the Clos Lucé near the Château d'Amboise; it is believed that he took the Mona Lisa with him and continued to work on it after he moved to France. Art historian Carmen C. Bambach has concluded that Leonardo probably continued refining the work until 1516 or 1517. Leonardo's right hand was paralytic c. 1517, which may indicate why he left the Mona Lisa unfinished.

Circa 1505, Raphael executed a pen-and-ink sketch, in which the columns flanking the subject are more apparent. Experts universally agree that it is based on Leonardo's portrait. Other later copies of the Mona Lisa, such as those in the National Museum of Art, Architecture and Design and The Walters Art Museum, also display large flanking columns. As a result, it was thought that the Mona Lisa had been trimmed. By 1993, Frank Zöllner observed that the painting surface had never been trimmed; this was confirmed through a series of tests in 2004. …

The Mona Lisa has survived for more than 500 years, and an international commission convened in 1952 noted that "the picture is in a remarkable state of preservation". It has never been fully restored, so the current condition is partly due to a variety of conservation treatments the painting has undergone. A detailed analysis in 1933 by Madame de Gironde revealed that earlier restorers had "acted with a great deal of restraint." Despite the treatments, the Mona Lisa has been well cared for throughout its history, and although the panel's warping caused the curators "some worry", the 2004–05 conservation team was optimistic about the future of the work.

At some point in the 16th century, a varnish was applied to the painting. At some point, the Mona Lisa was removed from its original frame. The edges of the painting have been trimmed at least once in its history to fit the picture into various frames, although no part of the original paint layer has been trimmed.

The first and most extensive recorded cleaning, revarnishing, and touch-up of the Mona Lisa was an 1809 wash and revarnishing undertaken by Jean-Marie Hooghstoel, who was responsible for the restoration of paintings for the galleries of the Musée Napoléon. The work involved cleaning with spirits, touch-ups of colour, and revarnishing the painting. This aggressive cleaning and revarnishing removed some of the uppermost portion of the paint layer, resulting in a washed-out appearance to the face of the figure.

The unconstrained poplar panel warped freely with changes in humidity, and as a result, a crack developed near the top of the panel, extending down to the hairline of the figure. In the mid-18th century to early 19th century, two butterfly-shaped walnut braces were inserted into the back of the panel to a depth of about one third the thickness of the panel. This intervention was skillfully executed, and successfully stabilized the crack. Sometime between 1888 and 1905, or perhaps during the picture's theft, the upper brace fell out. A later restorer glued and lined the resulting socket and crack with cloth.

In 1906, Louvre restorer Eugène Denizard performed watercolour retouches on areas of the paint layer disturbed by the crack in the panel. Denizard also retouched the edges of the picture with varnish to mask areas that had been covered initially by an older frame. …

The Mona Lisa began influencing contemporary Florentine painting even before its completion. Raphael, who had been to Leonardo's workshop several times, promptly used elements of the portrait's composition and format in several of his works, such as Young Woman with Unicorn (c. 1506), and Portrait of Maddalena Doni (c. 1506). Later paintings by Raphael, such as La velata (1515–16) and Portrait of Baldassare Castiglione (c. 1514–15), continued to borrow from Leonardo's painting. Zollner states that "None of Leonardo's works would exert more influence upon the evolution of the genre than the Mona Lisa. It became the definitive example of the Renaissance portrait and perhaps for this reason is seen not just as the likeness of a real person, but also as the embodiment of an ideal."

Where earlier critics such as Vasari in the 16th century and André Félibien in the 17th praised the picture for its realism, by the mid-19th century, writers began to regard the Mona Lisa as imbued with a sense of mystery and romance. In 1859, Théophile Gautier wrote that the Mona Lisa was a "sphinx of beauty who smiles so mysteriously" and that "Beneath the form expressed one feels a thought that is vague, infinite, inexpressible. One is moved, troubled ... repressed desires, hopes that drive one to despair, stir painfully." Walter Pater's essay of 1869 described the sitter as "older than the rocks among which she sits; like the vampire, she has been dead many times, and learned the secrets of the grave; and has been a diver in the deep seas, and keeps their fallen day about her."

By the early 20th century, some critics started to feel the painting had become a repository for subjective exegeses and theories. Upon the painting's theft in 1911, Renaissance historian Bernard Berenson admitted that it had "simply become an incubus, and [he] was glad to be rid of her." Jean Metzinger's Le goûter (Tea Time) was exhibited at the 1911 Salon d'Automne and was sarcastically described as "la Joconde à la cuiller" (Mona Lisa with a spoon) by art critic Louis Vauxcelles on the front page of Gil Blas. André Salmon subsequently described the painting as "The Mona Lisa of Cubism".

The avant-garde art world has made note of the Mona Lisa's undeniable popularity. Because of the painting's overwhelming stature, Dadaists and Surrealists often produce modifications and caricatures. …
