Merfolk

Origin

The earliest direct attestation is Oannes, the man-fish who, according to the Hellenistic Babylonian priest Berossus in Babyloniaca (c. 290 BCE, surviving in fragments), rose daily from the Persian Gulf to teach humanity writing and agriculture, returning to the sea at sunset; seventh-century BCE Assyrian reliefs from Nineveh already depict apkallu fish-men. In Greek tradition Triton, son of Poseidon and Amphitrite, appears in Homer's Iliad book 18 alongside the fifty Nereids, while the Sirens, originally bird-women in Homer's Odyssey book 12, were gradually re-imagined as fishtailed in the medieval Latin Physiologus (2nd-4th century) and the bestiaries of the ninth through twelfth centuries. The Nihon Shoki entry for the twenty-seventh year of Empress Suiko (720 CE) records ningyo caught on the coasts of Omi and Settsu. Hans Christian Andersen's Den lille Havfrue, published in Eventyr, fortalte for Born vol. 1 no. 3 (C. A. Reitzel, Copenhagen, 1837), fixed the modern merfolk story of self-sacrifice and the longing for an immortal soul, and the Disney animated film The Little Mermaid (1989) made that image canonical. Gary Gygax introduced 'merfolk' as a standard race in the Dungeons & Dragons Greyhawk supplement (TSR, 1975) and the Monster Manual (TSR, 1977).

Features

• Human torso joined to a fish tail, usually single but sometimes twin in older art
• Enchanting song and illusion magic alongside command of ocean elements
• Underwater respiration, swimming speeds described at thirty to forty knots, pressure tolerance
• Cities in trenches, reefs, and undersea caverns: Triton's palace, Andersen's sea-king's hall, D&D Olynth, Magic: The Gathering's Atlantean realms
• Their own aquatic tongues, classically Old Greek-derived or in D&D the Aquan dialect

Stories

In antiquity merfolk were givers of civilisation (Oannes) or numinous inhabitants of the sea (the Nereids); in medieval bestiaries they served as moral symbols of vanity and temptation. After Andersen, nineteenth- and twentieth-century literature turned them into tragic voices for the gulf between the sea and humankind, the cost of love, and the question of the soul. Since Disney's 1989 film the image is broadly popular, and Dungeons & Dragons, Magic: The Gathering, and Final Fantasy treat merfolk as the standard race of an undersea kingdom and as guides or companions in submarine adventures. The older predatory mode — Homer's Sirens luring sailors to wreck — survives in horror and dark-fantasy variants.

Weakness

Out of water, merfolk weaken in breath and movement, and the bargain for legs in Andersen's tale exacts both excruciating pain at every step and the loss of voice. The gulf with land peoples produces social, reproductive, and cultural isolation, and the very song, beauty, and scales that make them remarkable make them targets for human hunters and alchemists. From the Nihon Shoki onward, catching or eating merfolk is widely treated as an ill omen across both Eastern and Western traditions.

Cultural Significance

After the industrial revolution the mermaid became a favoured Victorian subject for sea, woman, and otherness, exemplified by John William Waterhouse's A Mermaid (1900, Royal Academy of Arts, London). The Japanese legend of Yao Bikuni, a nun who lived eight hundred years after eating ningyo flesh, is commemorated at Kuin-ji temple in Obama, Fukui Prefecture. Andersen, in a letter to Henriette Hanck in 1836, explained that Den lille Havfrue mirrored his unrequited love for Edvard Collin, linking the self-sacrifice motif to his own identity. The Disney 1989 ending, which replaces Andersen's tragic dissolution into sea foam with a wedding, has been argued over ever since.

Trivia

• Berossus' Greek 'Oannes' transliterates the Sumerian Uan / Adapa, named in cuneiform tablets dating back to around 1900 BCE.
• Homer's Odyssey book 12 gives no physical description of the Sirens beyond their voice; the fishtailed Siren is first explicit in the seventh-century Latin Liber Monstrorum.
• The closing turn of Andersen's story, in which the mermaid earns a soul by three hundred years' service, was added after the 1837 draft because of religious sensitivities Andersen anticipated.
• The Little Mermaid statue in Copenhagen harbour (Edvard Eriksen, 1913) uses the face of the ballerina Ellen Price, who declined to pose nude, and the body of Eriksen's wife Eline.
