The canvas depicts the mythological episode of Diana, or Artemis, goddess of hunting, and her nymph Callisto with whom Jupiter – Diana’s father – had fallen madly in love. Callisto, however, was destined to remain virgin as a creature devoted to the goddess Diana, so when the goddess discovered during a bath that her nymph had become pregnant to her father, she first transformed her into a bear and then killed her with an arrow. For this Jupiter turned dead Callisto into the constellation of Ursa Major. Tiepolo depicts quite faithfully the mythological episode by Ovid narrated in his Metamorphoses and he places the scene close to a cave where Diana and the nymphs are taking a relaxing bath after a hunt. Under a blue sky with a soft pink cloud you can see Callisto on the right with a swollen belly due to her pregnancy, which she is trying to hide from Diana by raising her hands and being helped by another nymph who tries to cover her with a cloth. On the left Diana stands tall with her hands resting on her hips and two little angels standing around her, while other nymphs, frightened by her anger, are on her sides and seem to want to hide behind the ground. Although this is his early work, it is characterized by the elements of Tiepolo’s painting. The dramatic and theatrical composition and large figures with exaggerated but loose gestures is, in fact, a recurring element in his work, as well as the use of color, which is still linked to the contrasting examples he had learned from Giovanni Battista Piazzetta and Federico Bencovich, but which he began to abandon here by moving towards dramatic but clearer and more brilliant chiaroscuro, which became a permanent element of his painting. The painting is part of series of four paintings of same size with mythological subjects from Ovid’s Metamorphoses, which depict Diana and Actaeon, The Rape of Europe, Apollo and Marsyas. The works are currently preserved at Gallerie dell’Accademia of Venice, but in the past they were all in Belluno. In 1898, in fact, Count Francesco Agosti, who lived in the city of Veneto, bought the Rape of Europe as well as Diana and Actaeon, while in 1907 the counts Capponi bought Diana and Callisto and Apollo and Marsyas. The paintings were attributed at the time to Venetian painter Sebastiano Ricci, and they were probably purchased over some years to decorate a palace in Belluno. In 1922 the four paintings were exhibited the Exhibition of Italian Paintings from the 17th and 18th Century, curated by Ugo Ojetti (Florence, Palazzo Pitti). On that occasion the paintings, that were presented as works by Ricci, were correctly attributed to Tiepolo and considered among his early works.

Giovanbattista Tiepolo was born in Venice, where he studied in the workshop of the Venetian painter Gregorio Lazzarini, who introduced him to the painting of the great Venetian masters of the past, such as Titian, Tintoretto and Veronese, but also his contemporaries Sebastiano Ricci, Giovanni Battista Piazzetta and Federico Bencovich. From them Tiepolo learned the theatrical style and violent chiaroscuro that characterized his altarpieces and great fresco decorations. From the middle of the 1710s’ Tiepolo obtained important commissions and began to paint altarpieces for the churches of Venice, among them Madonna del Carmine and the Martyrdom of St. Bartholomew, as well as the paintings for doge Giovanni II Cornaro. From the 1720s the painter began to gain more reputation, and both the clergy and the Venetian nobility commissioned paintings of religious subjects and portraits and especially frescoes with mythological and allegorical themes to decorate the great city palaces and the country villas. The wide and scenographic compositions with astonishing perspective views that Tiepolo expressed through clear graphic style, with bright colors and strong chiaroscuro which met the taste of his new clients. His popularity led him to paint the frescoes of the chapel of SS. Sacramento for the cathedral of Udine in 1726, Castello and Palazzo Patriarcale of the city, while the following year he traveled to Milan where he worked on the decoration of Palazzo Archinto and Palazzo Dugnani, with the Stories of Scipio Africanus. He went back to Venice in the 1730s where he worked on various decorations, also in Vicenza and then in Padua, where he painted the Martyrdom of St. Agatha. He also painted the works Madonna of the Rosary, Madonna with Child with Saints Hyacinth and Dominic, both preserved today in America, as well as the large altarpieces with the scenes of the Passion of Christ for the church of Sant’Alvise in Venice. The artist was still very much in demand, when he assumed his Giandomenico and Lorenzo as his assistants and he was called again to Milan, where he decorated Palazzo Clereci, then to Venice to paint the frescoes of the hall of Palazzo Labia with the Stories of Antonius and Cleopatra. In 1750 the Tiepolo family was in Würzburg, Germany, to decorate the residence of Prince Bishop Karl Phillipp von Greiffenklau with the Stories of Frederick Barbarossa. Once the works were complete, the Tiepolo family returned to Italy. In Vicenza they frescoed Villa Valmarana with the stories of Homer’s Iliad, Virgil’s Aeneid, Ariosto’s Iphigenia and Orlando Furioso and the Liberation of Jerusalem by Tasso. In 1761 Tieopolo moved to Spain with his sons to work in the service of King Charles III, who invited him to decorate the rooms of the Royal Palace in Madrid. Here he painted the allegorical subjects such as the Allegory of Spain, mythological pieces and the altarpieces for the church of Aranjuez. Tiepolo never returned to Italy because he died in Madrid at the height of his career in 1770. His sons returned to Venice and continued, especially Giandomenico, their father’s work dedicating themselves to fresco decorations.

The Accademia of Venice was founded in 1750 and the opening of the Gallerie dell’Accademia was linked to it with primarily educational purpose: in 1803 a decree established the need to adjoin a gallery next to the school that was used by the students who studied painting and sculpting.

In 1817 the gallery was opened also to the public. The gallery is located in the area of Dorsoduro, down by the Accademia bridge, in a complex including the church of Santa Maria della Carità, the Canonici Lateranensi convent and the Scuola Grande of Santa Maria della Carità, all situated in a single floor, divided into twenty-fours and covering 5537 square meters.

The first section of the collection includes the Presentation of the Virgin at the Temple and the Pietà by Titian (1538) and the Triptych of the Madonna della Carità by Antonio Vivarini and Giovanni d’Alemagna (1480). The collection also includes essays by the students of the academy and a collection of plaster casts (hence the plural name, gallerie) which were put on display in the exhibition with success in 1817.

The collection was enriched with the paintings brought from defeated France and with the masterpieces that were left to the museum by great collectors. However, the paintings were always linked to the Venetian culture and this feature was tried to overcome for the whole 20th century. Among these works was the legacy of Felicita Reiner (in 1833, but only formalized in 1850), which included masterpieces such as Piero della Francesca’s St. Jerome, Giovanni Bellini’s Madonna and Child and Saints Catherine and Mary Magdalene. The legacy of Girolamo Contarini (1838) included 180 works, among them Madonna of the Small Trees and the Four Allegories by Bellini, and six paintings by Pietro Longhi.

The emperor Franz Joseph grew the collection with Nicolò di Pietro’s Madonna and Mantegna’s St. George, Memling’s Portrait of a Young Man and Giorgione’s Old Woman. The gallery was radically reorganized in 1895 by the director Giulio Cantalamessa. He excluded all the 19th century artists and for the first time the exhibition was organized chronologically. He coordinated the cycles of the School of St. Ursula by Vittore Carpaccio and the School of St. John the Evangelist by Cima da Conegliano, previously divided in various locations. Under the direction of Gino Fogolari (1905) the museum acquired other fundamental masterpieces, such as the Tempest by Giorgione and the Crucifixion by Luca Giordano and the Feast at the House of Simon by Bernardo Strozzi.

In the post-war period the museum performed various changes, for example Titian’s Assumption of the Virgin, which was supposed to be placed in a specially designed room, was returned to the Frari church in Venice instead. The 19th century works that were already excluded from the exhibition were sent to the deposit at the museum of Modern Art in Ca’ Pesaro and the foreign art in the Galleria Giorgio Franchetti in Ca’ d’Oro. In the 1940s’ Vittorio Moschini and Carlo Scarpa wanted to perform a modern reorganization of the museum, including the 19th century salons, but which resulted quite impractical in the end. In these years Francesco Guardi’s Fire in the Oil Depot of San Marcuola and Montagna’s St. Peter and Donor became part of the collection.

In 1987 director Sciré decided to increase the exhibition space opening the gallery on the fourth floor with the graphic collection and a new deposit was opened on the top floor of the Palladio building. In the same year the collection was enriched with two cherubs and two allegorical figures representing Justice and Patience, taken from Giorgio Vasari’s ceiling in a room of Palazzo Corner on the Grand Canal. Between 2001-2003 the gallery was renovated expanding the exhibition areas and adding modern lightning in the rooms.
