Note 730 — BOOK XXXIII. THE NATURAL HISTORY OF METALS.647

See B. iv. c. 23. In the Origines of Isidorus Hispalensis, B. xix. c. 32, we find mention made of “A Samothracian gold ring, with an iron bezil, so called from the place of its invention.” Pliny has already made allusion to the luxurious habits of the slaves, in B. xiii. c. 4; and B. xviii. c. 2; a subject upon which Juvenal enlarges in his Third Satire.
