What is "caieta"

In Roman mythology, Caieta was the wet-nurse of Aeneas. The Roman poet Vergil locates her grave on the bay at Gaeta, to which she also gives her name (cf. Caietae Portus). The poet Ovid, working a generation later, provides an epitaph:

HIC • ME • CAIETAM • NOTAE • PIETATIS • ALVMNUS EREPTAM • ARGOLICO • QVO • DEBVIT • IGNE • CREMAVIT

"Here me, Caieta, snatched from Grecian flames, my pious son consumed with fitting fire." The fourth-century commentator Servius writes that there was some controversy about whose wet-nurse Caieta was: in addition to Aeneas, he offers Creusa and Ascanius as possibilities.
