This vessel has an ovate bowl with six gadroons and a lobed mouth. The shaft is formed by a triple knop, the upper and lower ones covered by enamelled gold mounts and the central one carved out of the rock crystal, with imitations of inset precious stones. The two enamelled gold mounts follow the same pattern of green scrolls framed by black whorls tooled in the gold, with a drop of red enamel in the centre to simulate a ruby cabochon. The turned stem is short, while the foot has six gadroons decorated with flower sprays and rows of seeds. The frontal gadroons contain representations of the four seasons of the year. Emerging from the lateral folds are some protuberances on which four serpents’ heads are carved, their tails descending all the way down the body of the vessel. On the lower part is a marine scene with waves and monsters. Arbeteta attributed it to the Sarachi workshop, possibly designed by Annibale Fontana.

Missing since an unknown date are the mounts of the foot and the cover, which must have been hemispherical in shape, gadrooned, and crowned with an acorn or baluster finial.

The decoration admits an allegorical reading, as Arbeteta pointed out, since it represents the four seasons in accordance with Roman and Christian visual traditions. The old man warming himself is a symbol of winter, while the goddess Flora is an evocation of spring. The pomegranates intermingled with flowers on the garland may be an allusion to Persephone, while Ceres, with her ears of corn and cornucopia, represents the summer, and Noah and the vine represent the autumn. The frontal and lateral gadroons are separated by the serpents’ tails. They may be an allusion to the monstrous Python, the daughter of Gea (the Earth), and by extension to Apollo, the god who killed her, and who symbolises the sun, responsible for the changing seasons. The lateral figures complete the reading. The young Bacchus raises the cup with the newly made wine, while the half-anthropomorphic dolphins on the waves might allude to the sailors who tried to kidnap him when he was travelling to Naxos as a youth. However, a more intricate interpretation is also possible, since they could also refer generically to the punishment awaiting those who oppose Bacchus/Dionysus, a burning issue in the context of Counter-Reformation Milan in the last two thirds of the 16th century, where there was little in the way of liberties and esotericism. It was in defence of these that an eccentric group of artists gathered in the Accademia della Val di Blenio and took Bacchus half-jokingly and half-seriously as their patron. One of those artists was the brother-in-law of the Sarachi brothers, Annibale Fontana, who may have inspired the subject. The female figure on the other side could be Amphitrite, the marine Venus or the image of Fortune. In any case, they are images of good omen related to wine and water, just as the serpent Python is related to the earth and Apollo to the sun. The lost decoration on the cover may well have completed the meaning of this apparently simple decorative programme.

The four seasons appear on numerous pieces from the Milanese workshops, normally accompanied by other scenes. There are coincidences with a ewer at the Museo degli Argenti, Inv. Gemme 1921, no. 488, with a handle in the form of a serpent, and with the jewel case of extraordinary quality, attributed to Fontana, that was donated by Infanta Isabella Clara Eugenia to El Escorial, now at the Royal Palace in Madrid, inv. 10012357. Although it is more delicate, the technical language of vessel O83 has points in common with the Grape harvest vessel at the Prado (O81), the flask decorated with scenes of Orpheus and Midas at the Museo degli Argenti in Florence (Inv. Gemme 1921, no. 620), and another flask with grape harvesting scenes, formally and thematically similar, at Dresden, Grünes Gewölbe, V.186. It is highly probable that all were made at the Sarachi workshop.
