After a few years the colony in Vinland were abandoned. Probably after a hostile attack by the native people. In a manuscript from the 600th century Navigato Sancti Brendani tells a story which is full of marvelous achievements and devout thinking that it for years was considered just to be a collection of tales. The story tells us that angels disguised as birds guided Brendan. He was also helped by whales to find his way on the Ocean.
Many scholars think that the voyages actually did take place.
It is supposed that Brendan set sail from Kerry on Ireland. They took a northerly course and eventually they came across an iceberg, which shows that they passed Greenland into Davis Strait. They also passed through an area of dense mist, which can be New Foundland banks where the warm Gulfstream meets the Artic current. Later Brendan and his men landed on a flat tropical island covered with exotic vegetation and surrounded by crystal-clear water. Beautiful birds and naked dark-skinned pygmies inhabited it.
