 The "thing" seen in Lagarfljót looked like either islands or humps out of water, distanced hundreds of fathoms apart, but no one saw that it had either a head or tail.The creatures were documented in annals with some frequency in subsequent times as well.The map of Iceland attributed to Bishop Guðbrandur Þorláksson, engraved in 1585 by cartographer Abraham Ortelius is another attestation.
