The sellisternium or solisternium was a ritual banquet for goddesses in the Ancient Roman religion.
In the sellisternium, the attending goddesses sat on chairs or benches (in Latin, sellae), usually in the company of exclusively female hosts and guests.
[2] A sellisternium for the Magna Mater was part of her ludi Megalenses; a representation of her temple on the Augustan Ara Pietatis probably shows her sellisternum, which includes Attis, her castrated consort.
[3] After Rome's great fire of 64 AD, a sellisternium was held to propitiate Juno.
The secular games had a sellisternium for Juno and Diana, and according to Macrobius, a seated banquet of the gods and goddesses alike was part of Hercules' cult at the Ara Maxima.
