St. Brendan was a monk who lived in Ireland in the 400s.

St. Brendan received a calling from God to go on an ocean voyage West to seek the Promised Land.

He and his crew of Irish monks sailed around the Atlantic for seven years, visiting Iceland and Greenland on the way.

They encountered many natural wonders on their trip unknown to Europeans, including volcanoes, whales and allegedly Judas Escariot trapped on an iceberg.

A written record of his travels tells of St. Brendan reaching the Promised Land, or the “Island of Delights.” If true, this could make St. Brendan the first European to visit North America. Details in the account lead some researchers to wonder if this Island of Delights was Oak Island.

Roman coins similar to these have been found on Oak Island. St. Brendan would have had access to these kinds of Roman coins.
