Paragon comes from the Old Italian word paragone, which literally means "touchstone." A touchstone is a black stone that was formerly used to judge the purity of gold or silver. The metal was rubbed on the stone and the color of the streak it left indicated its quality. In modern English, both touchstone and paragon have come to signify a standard against which something should be judged. Ultimately, paragon comes from the Greek verb parakonan, meaning "to sharpen," from the prefix para- ("alongside of") and akonē, meaning "whetstone."
