Books It Is Named Vermilion In Allusion To The Insect Or Vermes

from which it is prepared. This insect is the "coccus ilicis," which

feeds upon the leaves of the prickly oak in the south of Europe. Like

the "coccus cacti," it is covered with a whitish dust, and yields a

tinctorial matter soluble in water and alcohol. Kermes and the lac of

India doubtless afforded the lakes of the Venetians, and appear to have

been used by the earliest painters in oil of the school of Van Eyck. The

former, under the appellation [Greek: kurno kokino], is said to be

employed by the modern Greeks for dyeing their caps red.

Some old specimens of this pigment which the author obtained were in

drops of a powdery texture and crimson colour, warmer than cochineal

lakes, and having less body and brilliancy. They worked well, however,

and withstood the action of light better than the latter, though the sun

ultimately discoloured and destroyed them. In other respects, they

resembled the lakes of cochineal. As a colouring matter, kermes is only

about one-twelfth part as powerful as that substance.
