The Roman god of grain storage and the harvest festival Consualia was Consus.
Consus was an ancient Roman deity connected especially with grain, its storage, and the hidden fertility of the earth. His altar stood at the Circus Maximus and was traditionally underground or covered with earth. It was uncovered for rites, emphasizing the god’s association with grain concealed beneath the soil and stored after harvest.
The Consualia were celebrated on August 21 and December 15, with an additional sacrifice on July 7. Horses, mules, and asses were given a rest from labor and decorated with garlands, while chariot races—including races with mule-drawn vehicles—took place at the Circus Maximus.
Consus is often confused with Ceres, the goddess of crops and agriculture, or Ops, a goddess of abundance associated with the harvest. They were related in Roman agricultural religion, but Consus specifically governed stored grain. Roman legend also connected his festival with Romulus’s abduction of the Sabine women.
