"The tablet included a reference to something called "The Eye of Tiamat." It was a large jewel of some kind which supposedly endowed Marduk with great magical abilities."
Daniel Jackson[src]

The Eye of Tiamat is a jewel that the Goa'uld Marduk possessed. The eye was supposed to grant Marduk "magical powers". It was locked with him in his sarcophagus when his priests rebelled against him. Colonel Alexi Zukhov located the eye, but it was buried with him when he tossed a grenade at Marduk. The Eye was later recovered by Anubis, who used it to power the superweapon aboard his mothership. The Eye was destroyed when the Tau'ri managed to destroy the weapon's power core when Anubis attempted to destroy Vis Uban. (SG1: "The Tomb", "Full Circle")
