Illustrated Companion to the Latin Dictionary, and Greek Lexicon (Rich, 1849)

COS (ἀκόνη). A hone, whetstone, or grindstone; worked with water and oil (Plin. H. N. xxxvi. 47.), and by the same sort of machinery as now employed. The illustration (Cos/1.1), from an engraved gem, represents Cupid sharpening his arrows on a grindstone, exactly as described by Horace (Od. ii. 8. 15. ardentes acuens sagittas Cote cruenta).
