HELICON, (anc. geog.), a mountain on the borders of Bæotia and Phocis; of fertile ſoil, covered with woods, and very extenſive, its north ſide touching Phocis, and partly its weſt ſide, quite to Mychos, its utmoſt port-town. There alſo we have the river Helicon; which ſinking in the earth riſes again at ſome diſtance under a new name, Baphyræ. This mountain is the poets' ſport and delight: Heliconius the epithet; Heliconiades, and Heliconides, the muſes.
