While there are some correspondences between the ideas about genius and "juno", especially in the imperial age, the relevant documentation is rather late (Tibullus mentions it first). Dumézil also remarks that from these passages one could infer that every woman has a Venus too. As evidence of the antiquity of the concept of a "juno" of women, homologous to the "genius" of men, is the Arval sacrifice of two sheep to the Juno Deae Diae ("the juno of goddesses named Dea Dia"), in contrast to their sacrifice of two cows sacrificed to Juno (singular). However both G. Wissowa and K. Latte allow that this ritual could have been adapted to fit theology of the Augustan restoration. While the concept of a Juno of goddesses is not attested in the inscriptions of 58 BC from Furfo, that of a Genius of gods is, and even of a Genius of a goddess, Victoria. On this point it looks remarkable that also in Martianus Capella's division of Heaven a "Juno Hospitae Genius" is mentioned in region IX, and not a "Juno": the sex of this Genius is feminine.
