A local Brythonic deity of Gaul who was worshipped in the Garonne valley in southwestern France. As Abelio, inscriptions to this deity have been found at Fabas, Montauban-de-Luchon, Saint-Béat, Saint-Bertrand-de-Comminges in the Haute-Garonne, France. As Abellio inscriptions to this deity have been found at Aulon, Baucou, Boutx, Burglays, Cardeilhac, Garin, Saint-Aventin, Saint-Bertrand-de-Comminges; all in the Haute-Garonne region of France. Finally, an inscription to Abello was fount at Billiére again in the Haute-Garonne, France. Unlike many other gods Abelio has not been associated with a companion or linked with a Greco-Roman deity through interpretatio Romana.

His name suggests that he was a god of either apple trees or orchards and may be cognate with the insular Afallach.

He was also known (though to a lesser degree) as a solar deity in Crete and the Pyrenees. Which may suggest that he was a god of the ‘Summer Lord’ type associated with the fruitfulness of apple trees.
