High Kings were traditionally installed on the Hill of Tara. The Lia Fáil (pictured) which tradition says shouted the rightful king’s name when he placed his foot on it
The Irish Celtic God Cermait (Cearmaid) is the equivalent of the Dionysus-Osiris. Per wikipedia:
In Irish mythology, Cermait (modern spelling: Cearmaid) of the Tuatha Dé Danannwas a son of the Dagda. He was known by the epithet Milbél (honey-mouth. See alsoOgma). He was killed by Lugh after he had an affair with Lug’s wife. The Dagda cried tears of blood for his son. Cermait’s three sons, Mac Cuill, Mac Cecht and Mac Gréine, avenged his death, and went on to become joint High Kings of Ireland.
This would then mean that Lugh is the equivalent of the Greek Prometheus and his story does match Prometheus. Lugh is also a Celtic Trickster God, just like Prometheus.
Please notice the “Cear” in the Cearmaid name which is part of the word Osiris and Caesir, Czar, and Kaiser. They sound the same because these bloodlines came from Dionysus-Osiris.
