Tim Severin - a legend of the sea
Severin was fascinated by historical travel, he set out to prove that many ancient journeys were actually possible using period-accurate boats and equipment.
His most famous expedition was the Brendan Voyage (1976-1977), where he sailed from Ireland to North America in a leather boat, proving that early Irish monks, such as St. Brendan, could have reached the New World nearly 1,000 years before Columbus.
