Odd isn't it that others who did make the journey left archaeological traces of their having passed that way. St. Brendan and his pals did not.

The writings you refer to were written how long AFTER the event?

"There is very little secure information concerning Brendan's life, although at least the approximate dates of his birth and death, and accounts of some events in his life, are found in the Irish annals and genealogies. The first mention of Brendan occurs in Adamnan's Vita Sancti Columbae, written between 679 and 704 [That is 100 years AFTER his death]. The first notice of him as a seafarer appears in the ninth-century Martyrology of Tallaght.

The principal works devoted to the saint and his legend are a 'Life of Brendan' in several Latin and Irish versions (Vita Brendani / Betha Brenainn) and the better known 'Voyage of Saint Brendan the Abbot' (Navigatio sancti Brendani abbatis).

Unfortunately, the Lives and the Voyage provide little reliable information about his life and travels; they do, however, attest to the development of his following in the centuries after his death. An additional problem is that the precise relationship between the Vita and the Navigatio traditions is uncertain.

Just when the Vita tradition began is uncertain. The surviving copies date no earlier than the end of the twelfth century, but scholars suggest that a version of the Life was composed before the year 1000 [ That is almost 500 years after his death]. The Navigatio was probably written earlier than the Vita, perhaps in the second half of the eighth century [ 200 years after his death]. St Aengus the Culdee, in his Litany composed at the close of the eighth century, invokes "the sixty who accompanied St. Brendan in his quest for the Land of Promise".

A Curragh that could carry 60 men along with their provisions eh Raggy? How many did Tim Severin take with him? Troublle with believing old stories and myths is that if you believe any of it you have to give equal credence to it all.

I still stand by my original statement:

"There is no "Evidence" at all that St Brendan crossed the Atlantic"
