The Thurso Cross is found on the Skinnet cross slab in far northeast of Scotland at the Thurso Museum. The design in the middle of the cross is a variation of an ancient pictish symbol, the ramshorn. The ramshorn is a variation of the spiral. The spiral represents God with everything revolving around Him. The knotwork covering the rest of the cross is unending and thus cannot be untied. This symbolizes the knots, which bind the soul to the earth. These knots must be cut and broken for the soul to become free to begin the spiritual journey to heaven. The knotwork is also said to represent everlasting life.
