SIRAT: the passage in the O.C. Bible that describes human life as a journey across a narrow bridge (the Sirat) with "Paradise on my right. Hell on my left, and the Angel of Death behind."
Wikipedia article about the Sirat Bridge:
As-Sirāt (Arabic: الصراط), also called Sirat al-Jahim (English: The Bridge of Hell) is, in Islam, the hair-narrow bridge, which according to Muslim belief every person must pass on the Day of Judgement to enter Paradise. It is said that it is as thin as a hair and as sharp as a sword. Below this path are the fires of Hell, which burn the sinners to make them fall. People who performed acts of goodness in their lives are transported across the path in speeds according to their deeds leading them to the Hauzu'l-Kausar (the lake of abundance).
Interestingly enough, there is an analogous concept in Zoroastrianism, where it is called the Chinvat Bridge:
The Chinvat Bridge (Avestan Cinvatô Peretûm, "bridge of judgement" or "beam-shaped bridge") in Zoroastrianism is the bridge which separates the world of the living from the world of the dead. All souls must cross the bridge upon death.
I wonder which of them emerged first though...
Another noteworthy thing is that in Zoroastrian mythology, there is a story of a giant Worm that was worshiped by a king whose people opposed the Persians (read more here and here).
