Seal of the grand master of the Knights Templar
The Grand Masters of the Knights Templar during the later 12th and the 13th century used a double-sided seal which showed a representation of The Dome of the Rock on one side, and the Order's symbol of two knights on one horse on the other side.
This design is first attested as in use by Bertrand de Blanquefort, the order's sixth Grand Master, in 1158, forty years after its foundation, and it remained in use until the dissolution of the order in 1312.

A seal is a device for making an impression in wax, clay, paper, or some other medium, including an embossment on paper, and is also the impression thus made. The original purpose was to authenticate a document, or to prevent interference with a package or envelope by applying a seal which had to be broken to open the container.
