The manuscript room at the library maintains eighteen degrees Celsius, fifty percent humidity, and illumination dim enough to humble any reader. I spent a February afternoon hunched over a high‑resolution facsimile of folio 34r, tracing a single green strand as it wove through twenty‑three crossings without ever reaching an end.
The Grammar of Interlace
What distinguishes Celtic knotwork from every other decorative tradition is its absolute commitment to the unbroken line. The knotwork line admits no beginning and no conclusion.

“Every crossing is a contract between maker and viewer that nothing here has been left unfinished.”
