What is the name of the artifact that contains the Time Stone? The answer is the Eye of Agamotto.

In the Marvel Cinematic Universe, the Eye of Agamotto is a mystical artifact used by the Masters of the Mystic Arts. It contains the Time Stone, one of the six Infinity Stones, which gives its wielder extraordinary control over time. Doctor Stephen Strange discovers and studies the artifact at Kamar-Taj.

Strange uses the Eye during the events of Doctor Strange to manipulate time and trap Dormammu in an endless repeating bargain. This helps him defeat Dormammu without overpowering the ancient entity in direct combat. The Eye is therefore both a magical relic and a crucial tool in Strange's transformation from surgeon to sorcerer.

The Eye should not be confused with the Tesseract, which contains the Space Stone, or Loki's scepter, which contains the Mind Stone. The Aether is the name used for the Reality Stone in its fluid form. Later MCU events establish that the Time Stone is eventually surrendered and destroyed along with the other Infinity Stones.
