Ataegina

[5] The name Ataegina is most commonly derived from a Celtic source: according to Cristina Maria Grilo Lopes and Juan Olivares Pedreño, French scholar D'Arbois de Jubainville and Portuguese scholar José Leite de Vasconcelos interpreted her name as a compound from *ate- 'repetition, re-' *-genos '(to be) born'.

[9] Similarly, in a 1998 article, Eugenio Luján, based on the epigraphic evidence available until then, supposed that Adaecina is the original spelling of her name, and related it to Irish adaig,[a] and both deriving from a Proto-Celtic *adakī.

[12] Wolfgang Meid raises the possibility that Old Irish adaig may be a borrowing of Welsh adeg "time, occasion, period, seaspn", whose native Irish cognate is athach "interval, space (of time)", derived from Proto-Celtic *atikā, from Proto-Indo-European *h₂et-i-keh₂, from *h₂et- (“to go”), making a connection between these words and Ataegina unlikely.

[19] Spanish historian José María Blázquez Martínez [es] supported the idea of Ataegina's indigenous character, while remarking that a Celtic interpretation of her name as 'reborn' is "inviable", and that her connection to Irish 'night' is "difficult".

[31] In that regard, a dedication etched in marble was found in Augusta Emérita: the propitiator prays to Dea Ataecina Turibrig(ensis) Proserpina for her to avenge the theft of some pieces of clothing.
