A flowing black-and-grey linework composition featuring a serpentine dragon coiled into a circle, its open jaws and spiked crown forming a bold silhouette. Inside the circular frame sits an ornate Celtic knot pattern, interlaced to convey continuity and protection, while a band of runic-like characters adds a mystic, ancient vibe. Executed in a clean fine line style, the piece emphasizes precise line weight, crisp edges, and deliberate negative space to maintain legibility on different body areas. The dragon’s scales, head, and open maw are shaded with careful stippling and hatching to create texture and depth, while the knotwork is designed to read as a singular motif that can stand alone or merge with larger sleeve or back pieces. This tattoo design blends mythic symbolism with geometric pattern to produce a timeless piece suitable for black-and-grey ink lovers and fans of small-to-medium scale body art. The dragon traditionally symbolizes strength, courage, and guardianship, while the circular form represents eternity, unity, and the wholeness of life; the Celtic knotwork reinforces interconnection without a beginning or end.
