Irish legend claims that St. Brendan was the first to land on the shores of America. Brendan was on Slieve Daidche beside the sea and he saw in a vision a beautiful island with angels serving upon it. An angel came to him in his sleep and said "I will be with you from this throughout your lifetime and it is I who will teach you to find that island you have seen and have a mind to go to". Brendan built his ship and sailed westwards from Ireland in search of his promised land. The sea and wind drove the ship at will until Brendan reached the new land.
