While many have heard of Nessie, few have heard of his 'cousin' Morag, of Loch Morar.
Some of the earliest-known writings on Nessie's less well-known cousin shed new light on the community which lived in its shadow more than 100 years ago, according to the researcher who uncovered them.
Morag, a mysterious creature supposed to inhabit the depths of Loch Morar, in the Highlands, is the subject of three separate writings from Alexander Carmichael, a prolific gatherer of folklore in his day.
The scripts, believed to date from 1902, have been uncovered by the Carmichael Watson project at the University of Edinburgh library.
Dr Donald Stewart, a senior researcher on the project, discovered the texts while leafing through a "mad mixture" of folklore collected by Carmichael over 50 years.
"We were so pleased when we found them, it was just totally unexpected," he said.
The writings paint a conflicting view of Morag. On the one hand she is presented as a mermaid-like character with flowing hair, while another description paints her as a grim reaper whose sighting was viewed as a death omen.
In the first text, Carmichael states: "Morag is always seen before a death and before a drowning."
