Focus on this artwork and explain the Description.
The polyptych measures 280 x 250 cm, the panels measuring 157.20x79.6 (central one), 117.50x40 (side lower panels) and 48.9x37.8 (upper panels). The central panel depicts the Incoronation of the Virgin and, in the lower part, a Trinity and a choir of musician angels. This scene was inspired to the Byzantine mosaics that Gentile had seen at Venice in St. Mark's Basilica, as shown by the figures floating in the air and the shining gold background, which is very finely tooled. Jesus' garment is drawn over a silver sheet.
The four side panels show figures of saints: from the left are Saint Jerome, with a model of the church in his  hands, Saint Francis of Assisi, Saint Dominic and Mary Magdalene. The figures are located in a garden whose botanic species are painted in deep detail. Details include the ampulla (not painted, but engraved in gold) held by Mary Magdalene in her fingers' tips: later, influenced by Masaccio's realism, Gentile would paint the same subject as firmly hold in Mary's hands in the Quaratesi Polyptych.
The smaller panels in the upper cusps depict Saint John the Baptist Praying in the Desert, the Martyrdom of Saint Peter of Verona, Saint Anthony of Padua Reading and Saint Francis Receiving the Stigmata. The scenes include further examples of Gentile's attention to details, such as the quasi-pointillism technique used to render the wool of the figure in Peter's scene, or the fine hair of Saint John's cloth. It is likely that the central cusp originally  housed a panel with the Crucifixion, housed in the Pinacoteca's same room. Other small panels with saints, divided among several collections, have been also thought to be once in the side piers of the polyptych, now lost.
