268 THE CURIOUS LORE OF PRECIOUS STONES
The
ignorance in the Middle Ages of the art of gem-engraving often induced
the belief that engraved stones were the work of nature. A striking
instance of this was the celebrated stone over the figure of the Mother
of Jesus, on the tomb of St. Elizabeth of Marburg. On this gem appeared
two heads touching each other, and it was, according to tradition, not
a work of art, but a freak of the sculptress Nature. An oft-repeated
legend tells us that a former Elector of Mainz offered the whole
district of Amöneberg for this costly stone, which robber hands
removed at Cassel. It is in reality a fine onyx engraved with the
heads of Castor and Pollux.66
We
might be disposed to regard rather sceptically the tales regarding
wonderful stones bearing the image of Christ, or that of the Virgin
Mary, and we may be inclined to believe that the old accounts are
exaggerated or distorted by the pious imaginations of the writers.
Nevertheless, in our own time we have a well-attested case of the
discovery of such a stone.
In
1880, while visiting the village of Oberammergau, Bavaria, to witness
the Passion Play, Mrs. Eugenia Jones-Bacon, of Atlanta, Georgia, found
on Mount Kop-fel, which overlooks the village, a small stone composed
of chert and limestone, and having on its surface excrescences so
disposed that, when the stone was held at a certain angle, the shadows
cast by them formed a striking likeness of the head of Christ as
depicted in Christian art. This peculiar freak specimen has been
carefully examined by experts and has been pronounced to be entirely a
work of nature. The mineralogist is not disposed to see here anything
more than coincidence, and
