About
About Saint Brendan's Isle (San Borondón)
8th c. Navigatio Sancti Brendani voyage (Brendan the Navigator c.512–530) tells 7-year Atlantic circuit finding island paradise with Judas on rock, whale Jasconius, colony and ultimately Terra Repromissionis Sanctorum (Promised Land). From 9th c. Ebstorf/Beatus maps onward charted as Saint Brendan Isle usually near Canaries-Azores (28N 23W classic) until 19th c. Charles Laughton claims off Canaries; Tim Severin 1976–77 rebuilt currach voyage proved Atlantic crossing feasible (Ballyaday? Newfoundland?), lending kernel reality to voyage but not phantom island charted. Removed after Cook.
Why it mattersKey immram informing Columbus' western thought; raises 'kernel vs literal' problem like Ys; Severin's experimental archaeology classic.
