A client of
Madame Sosostris, famous
clairvoyante, in
T.S. Eliot's poem
The Waste Land.
The Greek root of her name, equus, means horse. Madame Sosostris has a bad cold, and may herself be hoarse.
The Latin root of her name, eques, means horseman or knight. Combined, we would have a knight mare.
The letters in her name, rearranged, spell "quiet one".
These insights and/or red herrings come courtesy of "Notes and Observations on T. S. Eliot's Early Poems", by Patricia Sloane.
*********************************
Gritchka says: Tell Ms. Sloane the Greek bit is an especially red herring: Greek for horse is
hippos. Latin for horse is
equus, which gives the derivative
eques,
equitis 'horseman'.
