Evidence & Historical Context
Editorially reviewedDocumented identification
An abstract Pictish motif of two opposed crescent-like forms carved on the ninth-century Ulbster Stone in Caithness.
Scholarly interpretation
“Double-crescent” describes the paired curves but does not establish that the form represents the moon or another celestial object.
Modern associations
Balance, transformation and identity are modern discovery associations suggested by the opposed curves and Pictish context.
Research warning
Do not assign lunar symbolism or modern geometric meanings as documented Pictish significance.
Provenance: This study is based on the Double-crescent Sign documented on the ninth-century Ulbster Stone in Caithness, supported by the cited Historic Environment Scotland record and scholarship on the wider Pictish symbol tradition.
Context note: "Double-crescent" is a modern geometric description and should not be treated as evidence of lunar symbolism. Balance, transformation and identity are modern discovery associations rather than documented Pictish meanings.

Double-crescent Sign
Two opposed crescent-like forms create the compact geometric motif known as the Double-crescent Sign, recorded among the carvings of the ninth-century Ulbster Stone in Caithness. Its name describes its shape rather than a known Pictish meaning.
