The Celts of what is now Ireland had a long history of body art, with a variety of tattoo techniques and motifs. Celtic tattoos, once nearly extinguished by history, have once again become popular, as an alternative to tribal tattoos which use imagery and techniques from the South Pacific. Celtic tattoo designs often feature the Celtic knot, a dense interconnected nest of strands that represent the totality of existence. Other Celtic tattoo ideas include the Celtic cross, the tree of life and other esoteric symbols from Celtic mythology and mysticism. Lean more about Celtic Tattoo Designs and Symbol Meanings.
