Sirens, like harpies, partake of women and of birds, in various ways. In early Greek art sirens were represented as birds with large women's heads, bird feathers and scaly feet and sometimes manes of lions. 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 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 characteristic, beautiful voices. Later Sirens were sometimes also depicted as beautiful women, whose bodies, not only their voices, are seductive. The fact that in Spanish, French, Italian, Polish, Romanian or Portuguese, the word for mermaid are respectively Sirena, Sirène, Sirena, Syrena, Sirenă and Sereia creates visual confusion, so that sirens are even represented as mermaids. "The sirens, though they sing to mariners, are not sea-maidens," Harrison cautions; "they dwell on an island in a flowery meadow." 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."
