Sirens

In Greek mythology, the Sirens were three dangerous bird-women, portrayed as seductresses. Roman poets placed them on an island called Sirenum scopuli. In some later, rationalized traditions the literal geography of the "flowery" island of Anthemoessa, or Anthemusa, is fixed: sometimes on Cape Pelorum and at others in the islands known as the Sirenuse, near Paestum, or in Capreae. All such locations were surrounded by cliffs and rocks. Sailors who sailed near were compelled by the Sirens' enchanting music and voices to shipwreck on the rocky coast.
When the Sirens were given a parentage they were considered the daughters of the river god Achelous, fathered upon Terpsichore, Melpomene, Sterope, or Chthon . Although they lured mariners, for the Greeks the Sirens in their "meadow starred with flowers" were not sea deities. Roman writers linked the Sirens more closely to the sea, as daughters of Phorcys.
Their number is variously reported as between two and five. In the Odyssey, Homer says nothing of their origin or names, but gives the number of the Sirens as two. Later writers mention both their names and number: some state that there were three, Peisinoe, Aglaope, and Thelxiepeia (Tzetzes, ad Lycophron 7l2) or Parthenope, Ligeia, and Leucosia (Eustathius, loc. cit.; Strabo v. §246, 252 ; Servius' commentary on Virgil's Georgics iv. 562); Eustathius (Commentaries §1709) states that they were two, Aglaopheme and Thelxiepeia. Their individual names are variously rendered in the later sources as Thelxiepeia/Thelxiope/Thelxinoe, Molpe, Aglaophonos/Aglaope/Aglaopheme, Pisinoe/Peisinoë/Peisithoe, Parthenope, Ligeia, Leucosia, Raidne, and Teles.
The Sirens of Greek mythology are sometimes portrayed in later folklore as fully aquatic and mermaid-like; the facts that in Spanish, French, Italian, Polish, Romanian and Portuguese the word for mermaid is respectively Sirena, Sirène, Sirena, Syrena, Sirenă and Sereia, and that in biology the Sirenia comprise an order of fully aquatic mammals that includes the dugong and manatee, add to the visual confusion, so that Sirens are even represented as mermaids. However, "the sirens, though they sing to mariners, are not sea-maidens," Harrison had cautioned; "they dwell on an island in a flowery meadow."
According to Ovid , the Sirens were the companions of young Persephone and were given wings by Demeter to search for Persephone when she was abducted. Their song is continually calling on Persephone. The term "siren song" refers to an appeal that is hard to resist but that, if heeded, will lead to a bad result. Later writers have inferred that the Sirens were anthropophagous, based on Circe's description of them "lolling there in their meadow, round them heaps of corpses rotting away, rags of skin shriveling on their bones."
As Jane Ellen Harrison notes of " The Ker as siren:" "It is strange and beautiful that Homer should make the Sirens appeal to the spirit, not to the flesh." For the matter of the siren song is a promise to Odysseus of mantic truths; with a false promise that he will live to tell them, they sing,
Once he hears to his heart's content, sails on, a wiser man.
We know all the pains that the Greeks and Trojans once endured
on the spreading plain of Troy when the gods willed it so—
all that comes to pass on the fertile earth, we know it all!
"They are mantic creatures like the Sphinx with whom they have much in common, knowing both the past and the future," Harrison observed. "Their song takes effect at midday, in a windless calm. The end of that song is death." That the sailors' flesh is rotting away, though, would suggest it has not been eaten. It has been suggested that, with their feathers stolen, their divine nature kept them alive, but unable to provide for their visitors, who starved to death by refusing to leave.
Sirens combine women and birds in various ways. In early Greek art Sirens were represented as birds with large women's heads, bird feathers and scaly feet. Later, they were represented as female figures with the legs of birds, with or without wings, playing a variety of musical instruments, especially harps. The tenth century Byzantine encyclopedia Suda[12] says that from their chests up Sirens had the form of sparrows, below they were women, or, alternatively, that they were little birds with women's faces. Birds were chosen because of their beautiful voices. Later Sirens were sometimes depicted as beautiful women, whose bodies, not only their voices, are seductive.
The first century Roman historian Pliny the Elder discounted Sirens as pure fable, "although Dinon, the father of Clearchus, a celebrated writer, asserts that they exist in India, and that they charm men by their song, and, having first lulled them to sleep, tear them to pieces." In his notebooks Leonardo da Vinci wrote of the Siren, "The siren sings so sweetly that she lulls the mariners to sleep; then she climbs upon the ships and kills the sleeping mariners."
In 1917, Franz Kafka wrote in The Silence of the Sirens, "Now the Sirens have a still more fatal weapon than their song, namely their silence. And though admittedly such a thing never happened, it is still conceivable that someone might possibly have escaped from their singing; but from their silence certainly never."
The so-called "Siren of Canosa" accompanied the deceased among grave goods in a burial and seems to have some psychopomp characteristics, guiding the dead on the after-life journey. The cast terracotta figure bears traces of its original white pigment. The woman bears the feet and the wings and tail of a bird. It is conserved in the National Archaeological Museum of Spain, in Madrid.
