Vagitanus

In ancient Roman religion, Vagitanus or Vaticanus was one of a number of childbirth deities who influenced or guided some aspect of parturition, in this instance the newborn's crying.

[1] Some sources relate it to the Latin noun vagitus, "crying, squalling, wailing," particularly by a baby or an animal, and the verb vagio, vagire.

Gellius quotes Varro, who is generally acknowledged also as Augustine's main source on ancient Roman theology:[8] We have been told that the word Vatican is applied to the hill, and the deity who presides over it, from the vaticinia, or prophecies, which took place there by the power and inspiration of the god; but Marcus Varro, in his book on Divine Things, gives another reason for this name.

"As Aius," says he, "was called a deity, and an altar was built to his honour in the lowest part of the new road, because in that place a voice from heaven was heard, so this deity was called Vaticanus, because he presided over the principles of the human voice; for infants, as soon as they are born, make the sound which forms the first syllable in Vaticanus, and are therefore said vagire (to cry) which word expresses the noise which an infant first makes.

[9] Despite the insistence on an etymological connection between the god's name and vagitus, Gronovius thought the correct form should be Vaticanus, and that Vagitanus was Vulgar Latin rather than classical.
