NATURAL HISTORY OF GEMS.
" Nomen a loco : vulgus in nigra radice cœrulea facie." But the older definition, quoted from Iacchus, shows the name originally designated the Sardonyx cut across tho layers, for he makes the stone distinguished by veins (bands) of Sard and black passing across a transparent white ground, " per album sardœ nigrajque venis transeuntibus" (xxxvii. 54). Köhler supposes, with good reason, that the first-mentioned two-coloured gem is Pliny's Arabian Sardonyx, " which retained no trace of the Sard," for if the third and uppermost layer of the Sardonyx be removed, the remaining two will give us the very characters in question.
This is the Nicolo of the Italians, a corruption of
Onicolo,
" a little Onyx," still called by the Germans
Onykel :
a traditionary name affording in itself a strong testimony that this was anciently the Onyx
par eminence ;
and, as a diminutive, presenting a curious analogy with the original name
ïíý÷ùí.
A most preposterous derivation for the modern title is indeed current, that the stone was so called after a certain famous (and fabulous) artist Nicolo, who worked in it in preference to any other ; equally ridiculous with that deduced by old Camillo from
Nicolaus,
signifying in Greek the " conqueror of nations," in virtue of which designation the gem makes the wearer victorious in battle ! A remark of the Pesarese Esculapius nevertheless valuable as testifying to the existence of the name Nicolo for this gem amongst the Italians of the 15th century.
This variety, or more correctly speaking, this method of cutting the stone and giving it its characteristic appearance, was unknown in Grecian art, the intagli occurring in it being invariably in the Roman manner, and in style all posterior to the reign of Nero. Infinitely the most splendid specimen both for natural quality and for art that has come under my notice was Hertz's, the
gem,
of his cabinet, an oval nearly two inches high, of the richest blue and
