Agates torn by the wintry rains from the mountains, and expe­rience attests the almost exclusive use of the Calcedony for signets by the Persians of his age.
In consequence of the abundance of this stone in Europe, almost the sole fitting material for the Glyptic Art produced by this region in as fine a quality as by the East, a larger number of modem works in relief will be found in Calcedony than in any other stone ; whereas genuine antique Camei in this single-coloured material are much rarer than upon the stratified species of the Quartz family. De Boot has (ii. 88), " In our. time (in 1609) cups, figures of princes, chaplets of beads, and an infinity of other things are made out of Calcedony. Its chief use is for seals, because the wax (i. e. the soft wax then used) does not stick to it."
