The Italian painter Andrea del Sarto (1486-1530) was one of the most important painters of the High Renaissance. His highly expressive use of color is unsurpassed in Florentine painting.
With Michelangelo and Raphael working in Rome, Andrea del Sarto became the leading painter in Florence following the death of Fra Bartolommeo in 1517, and through his pupils, II Rosso and Pontormo, he was a vital formative influence on the development of mannerism.
Andrea was born in Florence on July 16, 1486. He was the son of Agnolo di Francesco, a tailor (Italian, sarto), hence the name Andrea del Sarto. According to Vasari, who was a pupil of Andrea, he was trained with a goldsmith from the age of 7. An earlier source identifies Andrea's master, quite convincingly, as Rafaellino del Garbo, a highly competent and successful painter of the late 15th century. About the age of 20 Andrea set up an independent shop with Franciabigio, although he did not matriculate in the painters' guild until Dec. 11, 1508.

Early Period
In 1509 Andrea received his first important public commission for five frescoes in the entrance cloister of the Church of SS. Annunziata, Florence, depicting scenes from the life of St. Filippo Benizzi. Two further frescoes, the Journey of the Magi and the Nativity of the Virgin, added in 1511 and 1514, illustrate the very rapid development of his style. Of the panel paintings, the beautiful Mystic Marriage of St. Catherine (ca. 1512; Dresden) shows his deep understanding of Leonardo's art, particularly in the expressive and compositional use of chiaroscuro (light and shade). Andrea was very selective in the ideas and motifs that he derived from his great contemporaries Fra Bartolommeo, Michelangelo, and Raphael. His figures are not idealized but warmly human and even humorous. He showed a notably early interest in Northern woodcuts by such artists as Albrecht Dürer, Martin Schongauer, and Lucas van Leyden; and his interest in sculpture was not confined to the antique but extended to the use of actual models by his friend Jacopo Sansovino, with whom he shared a workshop from 1511 to 1517.

Middle Period
Between 1511 and 1526 Andrea painted the famous monochrome fresco cycle in the cloister of the Scalzo, Florence, which is one of the masterpieces of High Renaissance art. The elaborate, painted architectural setting and the sculptural clarity of the narrative established new standards in monumental fresco painting.
Outstanding among the panel paintings of this period are the Madonna of the Harpies (1517; Florence) and the Wallace Madonna (1517-1518; London). In these mature works the outward gaze of the saints and the compelling vibrancy of the color demand the devotional involvement of the spectator.
It was probably in 1517 that Andrea married Lucrezia del Fede, a widow, whose portrait he had included in the Nativity of the Virgin. Despite Vasari's condemnation, which was so readily accepted and elaborated in the 19th century, there seems to be no real evidence that Andrea suffered either moral or financial ruin as a result of this marriage.
Summoned by the French king, Francis I, he traveled to France in 1518, but his stay at Fontainebleau was very short for he was back in Florence by the autumn of 1519. The Charity (Paris) and the Portrait of a French Lady (Cleveland) are the only surviving paintings that he executed in France.
Andrea may have visited Rome in 1519-1520 in connection with the important commission from Pope Leo X for the decoration of the Medici villa at Poggio a Caiano, near Florence, since Andrea's fresco Tribute to Caesar (dated 1521) at the villa strongly suggests a direct experience of Raphael's work in Rome.

Late Period
Comparatively little is known of the later part of Andrea's life, although his presence is frequently documented in Florence and his paintings offer no real evidence of any extensive travels. In 1520 he purchased a site on the Via della Crocetta and built a house. In 1524 Andrea took his family to the Mugello to avoid the plague. There he painted the Pietà (Florence), which, though more restrained in its color and emotion than the earlier Pietà (ca. 1520; Vienna), forms the point of departure for the deliberately appealing beauty of the late works. The increasing idealization and the sometimes arbitrary but acutely expressive color of paintings such as the Quattro Santi (1528; Florence) and St. Agnes (1527-1528; Pisa Cathedral) provided a rich source of inspiration for the young generation of mannerist painters. Yet the powerful devotional feeling in these works is evident from the exaggerated praise that Andrea received from writers of the Counter Reformation.
He died of the plague on Sept. 29, 1530, and was buried by the religious confraternity of the Scalzo in the Church of SS. Annunziata.

His Character
Andrea seems to have been a kindly, unassuming man with high professional standards and a profound understanding of humanity. He was genuinely pious, sometimes working for a nominal fee or, as in the case of the Madonna del Sacco (SS. Annunziata, 1525), waiving his fee altogether. Vasari interprets this as timidity and weakness, but it is more likely that Andrea, who was patronized by the Pope and the King of France, was sufficiently prosperous to afford such generosity. His popularity in the 16th century is demonstrated by the survival of an exceptional number of copies of his works.
Commonly referred to as Andreino, he was short of stature, as noticeable in the self-portrait in the Journey of the Magi (SS. Annunziata). The most reliable record of his features is the self-portrait painted on a tile (1527-1528; Florence).

Franciabigio (1482 – January 24, 1525), was an Italian painter of the Florentine Renaissance. His true name may have been Francesco di Cristofano, however he also is referred to as either Marcantonio Franciabigio or Francia Bigio. He was born in Florence, and initially worked under Albertinelli until about 1506. In 1505 he befriended Andrea del Sarto; and by the next year, the two painters set up common shop in the Piazza del Grano. He was proficient in fresco and Vasari claimed that he surpassed all his contemporaries in this method. It however in his portraits, and not religious paintings and frescoes, that his painting gathers naturalistic power. In 1513, in the cloister of the Annunziata he frescoed the Marriage of the Virgin, part of a larger series mainly directed by Andrea del Sarto, and overshadowed by the latter's masterpiece of Birth of the Virgin[1]. Other artists working under Sarto at the cloister included Rosso Fiorentino, Pontormo, Francesco Indaco, and Baccio Bandinelli[2]. In 1514, he frescoed a Mategnesque Last Supper for the Convento della Calza in Florence[3]. In 1518-19, at the Convento della Salzo, in another series of frescoes on which Andrea was likewise employed, he executed the Departure of John the Baptist for the Desert, and the Meeting of the Baptist with Jesus. In 1520-21, at the villa Medici at Poggio a Caiano he frescoed a turgid Triumph of Cicero on the walls of the salon, but again he is overshadowed by Potormo's naturalistic lunette of Vertumnus and Pomona. The array of figures appears distraught rather than celebratory, the antique details are a melange of quotations, and the architect a fancy of Quattrocento style[4]. He painted a St Job altarpiece (1516, Uffizi). Various works which have been ascribed to Raphael are reasonably deemed to be by Franciabigio. Such as the Madonna del Pozzo, with its awkwardly muscular John the Baptist[5]; and some of his portraits, including the half figure of a Young Man (shown above). These two works show a close analogy in style to another in the Pitti gallery, avowedly by Franciabigio, a Youth at a Window, and to some others—which bear this painter's recognized monogram. The series of portraits, taken collectively, placed beyond dispute the eminent and idiosyncratic genius of the master. Two other works of his, of some celebrity, are the Calumny of Apelles, in the Pitti Palace, and the Bath of Bathsheba (painted in 1523), in the Dresden gallery.

Critical assessment and legacy
When compared to his younger contemporary colleague, del Sarto, Franciabigio appears more sculptural and less forward-looking. The Quattrocento monumentality (or stiffness) of posing is evident in figures. Franciabigio attends more to linearity and balance in fresco recalling Massacio, while the complexity and Sarto's paintings reflect an understanding of the dissipating velvety colorful fabric of molding that characterizes Venetian work, and the development of sway that will "mannerize" art in the decades to come.
