One was Conor mac Nessa, King of Ulster, whose druid told him of the crucifixion of Christ and who died of that knowledge.[35] The second was the wise judge, Morann, and the third Cormac, son of Art.

This knowledge was revealed to him by divine illumination, and thenceforth he refused to consult the druids or to worship the images which they made as emblems of the Immortal Ones.
[35] See the conclusion of the _Vengeance of Mesgedra_.
One day it happened that Cormac after he had laid down the kingship of Ireland, was present when the druids and a concourse of people were worshipping the great golden image which was set up in the plain called Moy Slaught.

When the ceremony was done, the chief druid, whose name was Moylann, spoke to Cormac and said: "Why, O Cormac, didst thou not bow down and adore the golden image of the god like the rest of the people ?" And Cormac said: "Never will I worship a stock[36] that my own carpenter has made.

Rather would I worship the man that made it, for he is nobler than the work of his hands." [36] The image was doubtless of wood overlaid with gold.
Then it is told that Moylann by magic art caused the image to move and leap before the eyes of Cormac.

"Seest thou that ?" said Moylann.
"Although I see," said Cormac, "I will do no worship save to the God of Heaven and Earth and Hell." Then Cormac went to his own home at Sletty on the Boyne, for there he lived after he had given up the kingdom to his son Cairbry.
