The Celtic Knot — No Beginning, No End
Celtic knots are single continuous interlaces—abstract eternity. They appear from roughly the 3rd century AD in Irish metalwork and reach a peak in the Book of Kells (~800 AD). Variants add corners for seasons/directions or circles for life cycles.
The Trinity Knot (Triquetra) — Unity & Eternity
Three interlocking arcs read as earth/sea/sky before Christianity and as Trinity afterward—both readings coexist. In jewelry, three points often map to love, honor, and protection or past, present, and future.
The Celtic Cross — Heritage & Faith
A Latin cross with a ring—High Crosses across Ireland (8th–12th centuries) taught Bible scenes to passersby. The ring mixes sun, structural, and theological readings at once.
The Triskele (Triple Spiral) — Motion & Growth
Newgrange's entrance stone (~3200 BC) carries triple spirals—older than Stonehenge. Unlike the static Triquetra, the Triskele reads as rotation: past/present/future or land/sea/sky cycles.
The Celtic Love Knot — Two Lives, One Bond
Two strands interwoven so neither can leave without unraveling both—sailor lore ties it to long voyages. The Motherhood Knot variant uses twin hearts plus child dots.
The Celtic Tree of Life (Crann Bethadh)
Branches and mirrored roots inside a circle map this world and the other; tribes kept a sacred grove tree. Jewelry uses it for new parents, reunions, and memorials. See Celtic Symbol for Family.
The oak was especially sacred; "druid" may derive from oak knowledge.
