How does this artwork elucidate its Description?
The work shows several  differences from the earlier Coronation now at the Uffizi. The gilded background has disappeared, replaced by a more realistic light blue sky. The composition is more advanced, perhaps inspired to the innovation introduced by Masaccio. Angelico here  depicts a rich  cyborium with Gothic triple mullions, supported by a series of polychrome marble steps, as the set of the Incoronation. Elements such as the  twisted columns show similarities with the tabernacles painted in the frescoes of the Niccoline Chapel in Rome.Such as in the Florence painting, the angels and the saints form the audience at the side of the central scene, but the figures are more defined and some are shown from back, and the pavement's tiles are painted according to geometrical perspective. Pope-Hennessy supposed that the angels were influenced by those in the San Brizio Chapel of Orvieto Cathedral (1447).
The work was executed with the extensive help of assistants, especially in the right side: for example, St. Catherine's wheel is painted approximatively, and some of the saints in this side have less expressive faces.
The painting has a predella with scenes portraying the Miracles of St. Dominic and, in the middle, the Resurrection of Christ. Such as in other Angelico's work, the predella scenes show an extensive use of geometrical perspective, enhanced by the use of alternatively empty and full architectures.
