Magrefah מגרפה
The Magrefah is an object or musical instrument that was used in the Temple of Jerusalem.
Its function is to produce a loud signal or sound by throwing or spinning it.
This signal activates a new sequence in the ceremony.
The descriptions of the Magrefah do not allow a clear reconstruction or definition, so this object is the subject of many discussions.
Abraham Portaleone was one of the first to publish a concrete description of the Magrefah in his book Shilte ha-Gibborim. 1612
Portaleone described a Magrefah according to his own ideas, differing from the minimal descriptions in the Talmud.
