In Irish myth, Newgrange is the home of Oengus Mac ind-Og
, the Irish version of Mabon ap Modron
. Keeping in mind the circumstances of the Winter Solstice
as given above, it is possible that Oengus represents the reborn sun
, as his Welsh counterpart Mabon does.
It is said that Oengus won Newgrange in a bet with his father the Dagda, but that Oengus had to relent and allow his father to live there some part of the year. Could this be a seasonal myth? And as the Dagda is identifiable in many respects with Bran the Fisher King, does this have a bearing on the Grail legend?
