I going to have to disagree with you strongly Ted on the wording. Egyption tombs have been referred to as "Time Capsules" for centuries.
In fact, "There were other time capsules 5,000 years ago as vaults of artifacts hidden inside the walls of Mesopotamian cities, along with Egyptian and other ancient tombs, which are effectively time capsules as well."~The Book of Record
Tombs hold the artifacts of past cultures, they are a living museum all within the confines of a capsule or cache. If you asked any Archaeologist or Historian, they would agree with me I'm sure.
