The feria of the Matralia was celebrated III Idus Iun. (June 11th) at the temple of the goddess Mater Matuta, the goddess Aurora in the Forum Boiarum. It was celebrated by Roman matrons, matrones and , a univir a woman married only once had the privilege of crowning the cult statue of Mater Matuta.
- Slaves were forbidden from entering the temple or participating in the ceremonies. For the Matralia a slave, was made to enter the sanctuary and then ritually slapped and expelled by a matron. The Roman matrons bore their sisters children into the temple, made offerings of cakes baked in earthenware pots, rocked the infants and asked the goddess' blessing for the child's welfare. The cult statue was then crowned with a garland by a 'univir'.
Archelogical activity at a temple of Mater Matuta outside of Rome, uncovered votives of the goddess holding an infant, or nursing it, confirming her relation to infants.
