Antonello da Messina instance of human
In his biography of the artist, Giorgio Vasari remarked that Antonello saw an oil painting by Van Eyck (the Lomellini Tryptych) belonging to King Alfonso V of Aragon at Naples and consequently introduced oil painting to Italy. Recent evidence indicates that an "Antonello di Sicilia" (di Sicilia meaning 'from Sicily') was in contact with Van Eyck's most accomplished follower, Petrus Christus, in Milan in early 1456. It appears likely that this was in fact Antonello da Messina as this would explain why he was one of the first Italians to master Eyckian oil painting, and why Christus was the first Netherlandish painter to learn Italian linear perspective. Antonello's paintings after that date show an observation of almost microscopic detail and of minute gradations of light on reflecting or light absorbent objects that is very close to the style of the Netherlandish masters, suggesting that Antonello was personally instructed by Christus. Also, the calmer expressions on human faces and calmness in the overall composition of Antonello's works appear to be owing to a Netherlandish influence. He is believed to have shared Van Eyck's techniques with Gentile and Giovanni Bellini.Between the years of 1456 and 1457, Antonello proved himself to be a master painter in Messina. He also shared his home with Paolo di Ciacio, a student from Calabria. The artist's earliest documented commission, in 1457, was for a banner for the Confraternità di San Michele dei Gerbini in Reggio Calabria, where he set up a workshop for the production of such banners and devotional images. At this date, he was already married, and his son Jacobello had been born.
In 1460, his father is mentioned leasing a brigantine to bring back Antonello and his family from Amantea in Calabria. In that year, Antonello painted the so-called Salting Madonna, in which standard iconography and Flemish style are combined with a greater attention in the volumetric proportions of the figures, probably indicating a knowledge of works by Piero della Francesca. Also from around 1460 are two small panels depicting Abraham Served by the Angels and St. Jerome Penitent now in the Museo Nazionale della Magna Grecia in Reggio Calabria. In 1461 Antonello's younger brother Giordano entered his workshop, signing a three-year contract.  In that year Antonello painted a Madonna with Child for the Messinese nobleman Giovanni Mirulla, now lost.
Historians believe that Antonello painted his first portraits in the late 1460s. They follow a Netherlandish model, the subject being shown bust-length, against a dark background, full face or in three-quarter view,  while most previous Italian painters had adopted the medal-style  profile pose for individual portraits.  John Pope-Hennessy described him as "the first Italian  painter for whom the individual portrait was an art form in its own right".Venice
Antonello went to Venice in 1475 and remained there until the fall of 1476. His works of this period begin to show a greater attention to the human figure, regarding both anatomy and expressivity, indicating the influence of Piero della Francesca and Giovanni Bellini. His most famous pictures  from this period include the Condottiero (Louvre), the San Cassiano Altarpiece and the St. Sebastian. The San Cassiano Altarpiece was especially influential on Venetian painters, as it was one of the first of the large compositions in the sacra conversazione format which was perfected by Giovanni Bellini (Antonello's surviving work in Vienna is only a fragment of a much larger original). It is also likely that Antonello passed on both the techniques of using oil paints and the principles of calmness on subjects' faces and in the composition of paintings to Giovanni Bellini and other Venetian painters during that visit. While in Venice he was offered, but did not accept, the opportunity to become the court portrait painter to the Duke of Milan.
