The name derives from the stucco faces personifying the winds that are set in medallions in the sixteen groins of the vaults. Each mask is different and together they make up a sort of anthology of caricatures. The role of the winds is to separate the celestial vault, with its deities and zodiac signs, from the earthly world where human life takes place, influenced by the stars.

The room was also called chamber of the Planets, Medallions, or Zodiac.
The central motif of the decoration in the room is astrology and the influence the stars have on man, as  the writing above the south door explains”DISTAT ENIM QVAE SYDERA TE EXCIPIANT” (from Giovenal) which can be translated: “it depends precisely on which stars greet you (at birth).

The division of the vault into panels is explained by the iconography: the geometric pattern places the device of Mount Olympus in the centre and around this the twelve Olympic deities (either frescoed or modelled in stucco) governing the zodiac signs.

These are represented around the vault as bas-reliefs and alternate with painted personifications of the months.

The influence on man of the different constellations and zodiac signs is instead represented at the top of the walls. The stories take place within medallions surrounded by paintwork made to look like marble.

Here we see how human existence is not only influenced by the signs of the zodiac but also by constellations outside the zodiac that are present from birth, the so-called “paranatellonta”. The whole  cycle is inspired by the ancient astrological doctrines in the works of Firmico Materno and Manilio.

Also interesting is the decorative theme in the corbels of the vault. These are supported by male and female satyrs with their arms raised to perform the role of telamons.
This was a more private room. During his visit in 1530 emperor Charles V was entertained here after lunching in the chamber of Amor and Psyche.

The room was decorated between 1527 and 1528 by: sculptor Nicolò da Milano (stucco figures and festoons), stucco worker Andrea di Pezi (acanthus leaves on the corbels and the moulded frames) and painters Anselmo Guazzi, Agostino da Mozzanica, Benedetto Pagni and Girolamo da Treviso.

Made of Brentonico marble are the door frames and fireplace, which also bears an inscription dedicated to the marquis.
