Marquesan cross is another symbol which is quite popular and widely used in many Polynesian tattoo designs. It’s often used to symbolize balance between elements and harmony. Its origin is unknown but some archeological study shows that it’s connected to turtle shell.
It’s sometimes confused with variation or style of lizard symbols. A method to distinguish them is finding out whether the symbol has “tail” and “head”.
Below are several design and photo samples of practical application of Marquesan cross in tattoos.
