Insular - The term derives from insula, the Latin term for "island"; in this period Britain and Ireland shared a largely common style different from that of the rest of Europe. Most Insular art originates from the Irish monastic movement or metalwork for the secular elite, and the period begins around 600 with the combining Celtic and Anglo-Saxon styles.
In Celtic Art, Celtic knots (also known as 'endless knots' or 'mystic knots') are series of overlapping or interwoven knots which have no clear start or end. However, while they may have perfected it, the Celts were knot the first to come up with the knot design. The origin of the Celtic knot may go back to the Romans but most likely has its roots even earlier in Byzantine Constantinople.
