The story of the word

Theophrastus reports that the stone took its name ἀχάτης from the Sicilian river Achates where it was found, and Pliny repeats him; the river's own name is not Greek. Latin achates gave Old French agate, and English picked it up in the sixteenth century. Printers later used agate for a type size of about five and a half points, named for the smallness of the stone.
