The Matres (Latin "mothers") and Matronae (Latin "matrons") were female deities venerated in Northwestern Europe, of whom relics are found dating from the first to the fifth century. They are depicted on votive offerings and altars that bear images of goddesses, depicted almost entirely in groups of three, that feature inscriptions (about half of which feature Continental Celtic names and half of which feature Germanic names) and were venerated in regions of Germania, Eastern Gaul, and Northern Italy (with a small distribution elsewhere) that were occupied by the Roman army from the first to the fifth century.
Matres also appear on votive reliefs and inscriptions in other areas occupied by the Roman army, including southeast Gaul, as at Vertillum; in Spain and Portugal, where some twenty inscriptions are known, among them several ones which include local epithets like a dedication to the Matribus Gallaicis "to the Galician Mothers"; and also in the Romano-Celtic culture of Pannonia in the form of similar reliefs and inscriptions to the Nutrices Augustae, "the august Nurses" found in Roman sites of Ptuj, Lower Styria.
Matres and Matronae appear depicted on both stones with inscriptions and without, both as altars and votives. All depictions are frontal, they appear almost exclusively in threes with at least one figure holding a basket of fruit in her lap, and the women are either standing or sitting. In some depictions, the middle figure is depicted with loose hair and wearing a headband, and the other two wear head dresses. In addition, snakes, children, and nappies appear. Other motifs include depictions of sacrifice--including burning incense, pigs, and bowls filled with fruit--and decorations of fruits, plants and trees. In most cases, the votive stones and altars are not found singularly, but rather in groups around temple buildings and cult centers.
Rudolf Simek comments that the loose hair may point to maidenhood, whereas the head dresses may refer to married women, the snakes may refer to an association with the souls of the dead or the underworld, and the children and nappies seem to indicate that the Matres and Matronae held a protective function over the family, as well as a particular function as midwives.
Information about the religious practices surrounding the Matres is limited to the stones on which their depictions and inscriptions are found, of which over 1,100 exist.
