The great menorah?........Is that like the great Pumpkin?.....
The "great menorah" was second only to the Ark of the Covenant as a mighty Hebrew relic. The Menorah was carried away by the soldiers of Titus in the destruction of Jerusalem, and actually appears in a relief on the Arch of Titus in Rome. (A soldier is carrying the Menorah in the triumphal procession; presumably the artist thought that it looked curious enough that it was memorable and worth depicting.)
The menorah is the least significant element of the story of the rededication of the altar.
Its funny how movies always seem to focus on some almost insignificant facet of the real story.
