Myth and Folklore Wiki

Mermaids are legendary, aquatic creatures with the head, arms and torso of a female human and the tail of a fish. Male versions are known as "mermen." Their name originates from the word mer meaning 'sea' (In Old English it is more commonly written as mere).

Depending on the story or locale, mermaids can be portrayed as either good and helpful, mischievous and playful, or even destructive and territorial. In general, sailors are encouraged to avoid them as much as possible and be cautious should an encounter be made.

Myths and Legends[]

Mermaids enjoy singing and combing their long hair. At times, they will lure sailors to the rocks with their songs, or encourage handsome young men to their homes in the deep seas. Unsurprisingly, this usually results in the human drowning, but in some cases the men survive to see their underwater kingdoms. Mermaids live for a very long time but, according to some legends, do not have a soul.

Some of the bad things that mermaids are accused of include telling sailors their ship is doomed and enchanting sailors and causing shipwrecks. Seeing a mermaid is a sure sign of a violent storm to come.

However, on occasions, mermaids can also bring good fortune by giving humans cures or granting them wishes. In some tales, they even marry and live with humans.

It was always considered most unlucky to do anything unkind to Mermaids. As an aquatic being, they fail to thrive if brought onto land. The exception to this is the Merrow who sometimes marry humans.


Although some mermaids are described as monstrous and ugly, they are more usually very beautiful. Above the waist they appear as a lovely young woman, whilst from the waist down, they are like a fish with fins and a spreading tail. Mermen, however, are usually wilder and uglier than mermaids and have little interest in humans.

Cornish Myths[]

A peninsula in Cornwall called The Lizard has a high plateau surrounded by the sea, with numerous hidden little coves and beaches, just the sort of area for mermaid stories.

Many Cornish people, particularly sailors, have claimed to have seen or heard a mermaid and belief in them was once widespread. They hold many stories of mermaids which were seen on the rocks and of mermaids sitting weeping and wailing on the shore.

The mermaids in Cornish stories possess many of the features common among mermaids the world over. They are beautiful, often seen combing their golden hair and live for a long time without ageing. However, their mermaids are commonly more curious about humans, and sympathetic to their plight. As such, some people were said to have obtained knowledge of healing, of the future, and other supernatural abilities from them, which they could then pass down. For example, preparing a vessel of water could then show the face of a thief, which is a common means of detection that occurs in many myths.

Variations between Regions[]

All sea-faring cultures have mermaid tales. The Aegean Sea especially, it seems, was full of such creatures. In the Breton ballads there are the 'Morgan' (sea-women), and 'Morverch' (sea-daughters).

In British folklore they can be bringers of bad fortune, capable of causing storms which doom ships and their sailors. In some stories, they deliberately drag people down in the water and squeeze the life out of drowning men.

In Ireland and Scotland there are the 'Merrow', which are said to be beautiful, gentle, modest and kind. They wear a red cap and, if this is captured and hidden from them, they will shed their skins and stay on land. However, most times they eventually retrieve the cap and return to the sea. They also lure young men to follow them beneath the waves. Here they live in an enchanted state. Merrow music is often heard coming from beneath the waves.

In Greek legends there are mermaids that can sink ships and sirens that lure sailors to their doom. In a silvery cave, live the golden haired Haliads or sea nymphs that helped sailors fighting perilous storms. They are depicted as human from the head to the waist, with either a bird's body or a fishes tail. Other sea dwellers from Greek legend include the 3000 Oceanids, the daughters of the Titans Oceanus and Tethys.

Similar creatures to mermaids can also live in lakes and rivers. In Slavic mythology there are the Rusalki, the spirits of young women who have met their fate through drowning. They appear in the form of beautiful fish-women or mermaids. They have lovely hair, fine features but sad fathomless eyes which tell their tragic tale. They entrance young men, taking them to the river floor to live with them.

How did the myths arise?[]

Mermaid and merman

Mer people

Legends of half-human, half-fish creatures go back thousands of years. Everyone has seen pictures of mermaids. Sightings were made by the early Arabs and the Greek Pliny in 586 A.D. Many medieval sailors claimed to have seen them and such reports continued right into the 1900's.

Most sightings by sailors were probably normal marine creatures, such as manatees, dugongs, or sea-cows (now extinct). These appear to cradle their young much as a human would carry a baby. It is possible that sailors, seeing these unfamiliar beasts, would assume that they had stumbled across some sort of humanoid species. Mermaids described by the famous explorer, Christopher Columbus, were almost certainly manatees. He reported seeing three mermaids in the ocean off Haiti, in January of 1493. He said they "came quite high out of the water", but were "not as pretty as they are depicted, for somehow in the face they look like men." 

However such descriptions are very different from the usual portrayal of a mermaid and the idea, of a beautiful but dangerous creature, probably arose from the earlier stories of the Sirens of the Aegean Sea. The Sirens were sea-nymphs who had the power to charm by their song all who heard them, so that the unhappy mariners were irresistibly impelled to cast themselves into the sea to their destruction. The Sirens were first mentioned in Homer's Odyssey. This may have shaped the portrayal of mermaids from medieval times onwards.  

Modern Depictions[]

Mermaids are one of the most famous mythical creatures, depicted regularly in literature and film. The "Mermaid's Rock" can still be seen off the coast and you can visit Kynance cove and the beaches by the Lizard.

The modern view of mermaids has also been influenced by Hans Christian Andersen's fairytale, The Little Mermaid, written in 1836.
