Oracle

"The oracle-glass was maddeningly literal, capable of answering only the question one asked, rather than that which one wanted answered."

"Ibis redibis non morieris in bello."

"A Delphic sword."

"The oracles are dumb, No voice or hideous hum Runs thro' the arched roof in words deceiving."

"I am Sir Oracle, And when I ope my lips let no dog bark!"
