There are many different stories about the Holy Grail.

Holy Grail as a Cup

Many stories of the Holy Grail identify it as a cup.

Cup of Jamshid

I've conjectured that likely the stories of the Holy Grail as a cup come from the stories of the: Cup of Jamshid.

A cup which is said to also gone by the names: Jam-e Jahan nama, Jam-e Jahan Ara, Jam-e Giti nama, and Jam-e Kei-khosrow.

This story was likely transmitted via the Alans through what is often called the Nart Sagas. (From what I've gathered, the cup from the Nart Sagas is called: Nartyamonga.)

(The link being that the Alans were (originally) the same people as the Iranians, with a similar culture, and thus brought this story with them.)
