Nessie, the monster that supposedly inhabits Scotland's Loch Ness, was first documented in the 7th century. According to the Life of St. Columba, written by one Adomnán, an Irish monk, St. Columba, witnessed the burial of a man along the River Ness. The monk was told that the man was killed by a "water monster." He then sent one of his followers to swim into the river, and the beast reappeared,
... but Columba made the sign of the cross and commanded: "Go no further. Do not touch the man. Go back at once." The beast immediately halted as if it had been "pulled back with ropes" and fled in terror, and both Columba's men and the pagan Picts praised God for the miracle.
There were two separate sightings within a month of each other in 1933. Both of the witnesses claimed to have seen some sort of large animal crossing the road in front of them. Another sighting occurred in 1943, and a large object was detected in the loch with sonar in 1954. The most famous sighting of Nessie came when she was supposedly photographed in 1934 by Dr. Robert Wilson, but the photo was later deemed a hoax.
