P3R-272

P3R-272 is the name the the SGC gave a planet that was once colonized by the Ancients. The Stargate was located in a room with no doors, windows, or obvious power sources. All that was visible was a small circular inscription on the floor:
 * "Noo ani Anqueetas. Hic qua videum".

After Jack O'Neill stepped over the inscription, a device appeared on a wall, which then downloaded something into O'Neill's brain. O'Neill was soon able to translate the inscription:
 * "We are the Ancients. The Place of Our Legacy."

It was soon learned that the device had downloaded the knowledge of the Ancients into his memory.
