Notes on verification

Widely corroborated by UNESCO, Britannica, Spanish government heritage sources, and academic literature affirming a thousand-year tradition, typically traced to c. 960 AD. However, documented written evidence only extends to the 18th century, with earlier history resting on oral tradition and later scholarly inference; some historians explicitly caution against taking the millennium framing as documentary fact.
