Of Gems. 
Part III. 
00 Lib, 7. by Pliny, (a) of Pyrrhus King of £pj/r^, in which, without 
c 11. much (train of phancy, one might imagine a reprefenta- 
tion of the Nine Mufes, and Apollo, with his Harp, in the 
middle of them. Tis ufed for Sword-Hilts, Knife-Hafts, 
Beads, Cups, and the like. There are pieces of it, fometimes 
Septal ' (b) as thick as a Mans Arm. 
The ONYX. So called, becaufe in colour not unlike the 
Nail of a Mans Finger. Ambrofinus confounds the Agate 
and the Onyx together. But the Onyx differs from the 
Agate, chiefly, in that, inftead of Veins, 'tis generally com- 
pofed, faith Boetius, of Zones. But I think rathgr of feveral 
Balls, one within another : which, when the Stone is po- 
lifh'd, do indeed reprefent a round fpot in the centre, with 
feveral Zones or Rings about it. Here are of divers

An ONYX with a white, and very broad Zone. 
ANOTHER, of a pale Blew. 
A THIRD, with Rings White and Bay. 
A FOURTH, of a light yellowifh colour, or of Citrine

A SIXTH, with the middle Spot or Pupil encompaffed 
with a grey Ms. 
A SEVENTH, with the Im party-colour d , within , 
White 3 without, brown 3 and the Pupil alfo of the fame

An EIGHTH, with an afh-colour'd Pupil, the Iris of a 
pale Amethyftine within, and white without. Thefe with 
more variety of colours, are by fome particularly called 
NICCOLI-j qu. Onyculi. 
A NINTH, which maybe narnU The BIN0CVLAR b 
as having the likenefs of two little Eyes. The Table on 
which Nature hath drawn them, is of , the colour of yellow 
Amber , and femiperfpicuous. The Eyes are white, with 
their Pupils of the colour of the paleft live Honey. 
A TENTH, dimndtly called BELI OCVLVS : the Iris 
whereof is Gr*ey 3 the Pupil, and the reft of the Eye, 
Black. 
An ELEVENTH, of the colour of yellow- Amber, with 
grey Girdles, not round, as in all the former, but angular.
