B’fhearr "An Odaisé" ná "An Odyssey" a thabhairt ar aistear Odaiséis a scríobh Hóiméar.

A Shéamuis, ná bac leis! Cac is ea é! Aistriúchán innille is ea é!
Séamus, the one you linked is AI-generated crap.
A (or even 'the'; I'm not aware of alternatives) legit translation is An Odaisé by Monsignor Pádraig de Brún, edited by Ciarán Ó Coigligh. See e.g. https://archive.org/details/isbn_9780049000001.
(There's also a picture book for children "An Odaisé" from Leabhar Breac, ISBN 978-1-911363-03-3).

Go raibh maith agat, a Ghreásaghais, nách mise atá baoch nár cheannuíos an leabhar lofa san! Tá ana-chuid leabhar foilsithe aige Clasaicí Beaga Bídeacha (isiad so a dh'fhoilsigh An Odaisé): An Odaisé, Romeo agus Juliet, Frankenstein, Oileán an Órchiste, Don Cíochótae, Camchuairt Ghuilivéir
