Opening the World of Ceres
August 24
(Roman) Ancient: IX Kal. Sept.
On this day the Mundus Cereris (World of Ceres), a two-compartment vaulted ritual pit, is opened, which occurs on
only two other days (Oct. 5, Nov. 8). Since its lid, the Lapis Manalis (Stone of the Manes), is considered an
Ostium Orci (Gate of Hades), the Manes (ancestral spirits) are freed to roam the streets; therefore no marriages,
battles, business or enterprises of any kind is conducted. First-fruit offerings to the Manes may be placed in the
pit.
