Harpe (ハルペー, Harupei?) is a divine sword from Greek mythology, the snake hunter's scythe, used by Perseus to kill the Gorgon Medusa and one of the many weapons inside Gilgamesh's Gate of Babylon. It is described as a monster-killing holy sword with a special shape similar to a scythe, having the cutting edge on the inside of the blade, though it isn't actually an outstanding sword by itself. Its true strength is its trait of Refraction of Longevity (屈折延命, Kussetsu Enmei?), which is a divine ability that nullifies the "undying attribute" of immortals and inflicts wounds that cannot be restored by any methods other than healing in accordance to the natural laws. It is one of five Noble Phantasms given to Perseus, the most legendary artifacts given to a single person in Greek history, for his quest to slay Medusa. It was given by Hermes, and as it was returned to him once the task was completed, it can be called an “Anti-Medusa” weapon.
The other Noble Phantasms included a helmet of invisibility, a mirror shield, the mystical bag, Kibisis, and winged sandals capable of flight. The sandals were also given by Hermes, and the shield was given by Athena. The mirror shield is a bronze shield polished to bear a mirror-like reflection that projects information from the surrounding environment on its surface so the user can rely on that information to move around without having to move himself away from the mirror. It can also be used as a sort of detection device as it transmits the heartbeats of those in the area. He did not use it to reflect Medusa's Mystic Eyes like in the legends, but instead focused only on the projected information to find her location and avoid having to look upon her.
The sandals were quick enough to allow him to avoid her strikes for a long period of time. Kibisis (キビシス, Kibishisu?) is a anti-sealing Noble Phantasm that distorts the concept of the world, placing the inside of the pouch on the outside and the outside of the pouch on the inside. It inflated and swallowed Perseus, creating a fold in space that placed the outside world into the inside of the bag, and Breaker Gorgon, which affects only what is inside, was reflected back, making Medusa look upon herself as if reflected in a mirror, allowing him to slay her with Harpe while she was immobilized.
Fate/complete material II - Harpe English | JapaneseUser: Gilgamesh
A divine sword from Greek mythology. One of the Noble Phantasms owned by Gilgamesh. It has a special shape similar to a scythe, with the cutting edge on the inside of the blade. It also has the power to negate the “undying” attribute. The hero Perseus received the sword from Hermes, so that he could exterminate the snake-haired witch Medusa. The legend goes that Perseus approached Medusa – who would turn everybody that looked at her into stone – by using a mirrored shield, and then cut off her head with Harpe while she slept. Because Perseus returned Harpe to Hermes once the task was completed, it can be considered an “Anti-Medusa” weapon.
