In this imaginary, idyllic realm, classical philosophers and scholars gather to teach and learn. The men and women in the foreground examine a book of astrological signs. Behind them, a second group studies an armillary sphere, a celestial globe invented in ancient times that became a symbol of knowledge during the Renaissance. A woodcut version of this scene appeared as an illustration in the fortunetelling book <em>Garden of Thoughts</em>, published in Venice in 1540. In that context, the group of three women in the foreground might be seen as the three fates, and the man with the globe as a personification of astrology.
