HARPE (ἅρπη). A particular kind of sword or dagger, with a hook like a thorn (hamus), projecting from the blade at a certain distance below the point (mucro); as shown by the figure on the top of the opposite page. This weapon is fabled to have been used by Jupiter (Apollodor. Bibl. i. 6.), Hercules (Eurip. Ion., 191), and more particularly by Mercury and Perseus (Ov. Met. v. 176. ib. 69.), to the last of whom it is universally assigned, as a characteristic weapon, by the ancient artists in their sculptures, paintings, and engraved gems.
