Etymology : With a name literally meaning “beautiful-voiced” (from kallos, meaning “beauty,” and ops, meaning “voice”), Calliope was the most prominent of the Muses—the nine sister goddesses who in Greek mythology presided over poetry, song, and the arts and sciences. She is represented in art as holding an epic poem in one hand and a trumpet in the other. The musical instrument invented and patented in the 1850s, played by forcing steam or compressed air through a series of whistles, was named after the goddess. Because its sound could be heard for miles around, the calliope was effective in luring patrons to river showboats, circuses, and carnivals, which is why the instrument continues its association with such attractions today.
