bilunarmynstur

Bilunarmynstur is a decorative motif used in art and design to depict two crescents or lunar phases in relation to one another. The term comes from Icelandic bilunar, meaning two moons, and mynstur, meaning pattern. In typical renderings, the two crescents may mirror each other, face in the same direction, or be interlocked with geometric elements such as circles or rays. The pattern is often repeated in bands or tessellations.

Historically, bilunarmynstur has been observed in Nordic and northern European decorative traditions and has been revived in contemporary graphic and textile design. It is valued for its geometric simplicity and symbolic associations with cycles, time, and renewal. Variants exist where the crescents are stylized as arcs or split crescents, and where accompanying motifs alter the rhythm of the pattern.

In practice, bilunarmynstur appears on textiles, pottery, metalwork, architectural decoration, jewelry, and modern logos. Designers may use it to convey a northern or lunar aesthetic, or to invoke notions of balance and continuity. The motif is often contrasted with single-lune patterns or other crescent motifs to achieve variety within a restrained palette.
