Goa'uld ark
THE STARGATE OMNIPEDIA
GOA'ULD ARK
Combination-lock box of Goa'uld design, often used to hold gifts or valuable possessions. One such ark was uncovered on Earth by the Nazis during World War II, eventually ending up in the hands of rogue N.I.D. agents in a secret Los Angeles research facility. This box was adorned with a gold motif of the sun god Ra, and likely originally contained a gift to his ally, Sekhmet.

To open an ark, one must perfectly align the four scarabs on the top surface, like a combination lock. The box will immediately open, allowing access to the inside. Goa'uld crystals can also be installed at one side of the box to protect the contents, such as a Goa'uld bomb.

The System Lord Baal has been known to give exploding gifts to his enemies. It is very likely he may use arks, or something similar, to conceal such devices.

Believing that her captor, Dr. Keffler, would be able to grant her total reign over her body (the young girl Anna), Sekhmet located the ark in the L.A. lab and set the bomb within it on a count-down to detonatation, in order to persuade him to help her.
