Note 1338 — BOOK XXXIV. THE NATURAL HISTORY OF METALS.
John Bostock translation
The term signum, which is applied to the Corinthian figures, may mean a medallion, or perhaps a seal-ring or brooch; we only know that it must have been something small, which might be carried about the person, or, at least, easily moved from place to place.—B. Statuette, probably.
