"The urim and thummim was a name given to the jewelled plate which lay
upon the breast of the high priest of the Jews. They had a very
special feeling of reverence for it--something of the feeling which an
ancient Roman might have for the Sibylline books in the Capitol. There
are, as you see, twelve magnificent stones, inscribed with mystical
characters. Counting from the left-hand top corner, the stones are
carnelian, peridot, emerald, ruby, lapis lazuli, onyx, sapphire, agate,
amethyst, topaz, beryl, and jasper."
