Frog tattoos are not exactly the prettiest or the most artful in the history of tattooing, but their unique looks make them a favorite amongst many ink enthusiasts. From the beginning of time, tattoos of frogs were worn by ancient peoples because of their deep meanings and representations. For example, the Celts adopted this tattoo style because they believed that frogs signify healing. These creatures were associated with water and rain, and the Celts believed that they had the power to cleanse an individual from his sicknesses. As for the Haidas, they believed that frog tattoos meant harmonious balance. Just like the symbol of Yin and Yang, those who have this ink believe that their lives are in a state of equilibrium.
